903.9.2 General Information Signs (I Series) (MUTCD Section 2H.02)

Support. Of interest to the traveler, though not directly necessary for guidance, are numerous kinds of information that can properly be conveyed by General Information signs or miscellaneous information signs. They include such items as Missouri State line (I2-1), City limit (I4-1, I4-2), town signs (I5-1), County line (I6-1)and stream names (I3-1).

Option. The pictograph of a political jurisdiction (such as a state, county, or municipal corporation) may be displayed on a political boundary General Information sign.

Standard. If used, the height of a pictograph on a political boundary General Information sign shall not exceed two times the height of the upper-case letters of the principal legend on the sign. The pictograph shall comply with the provisions of EPG 903.2.14.

903.9.3 Miscellaneous Information Signs (MUTCD Section 2H.04)

Support. Miscellaneous information signs are used to point out geographical features, such as rivers and summits and other jurisdictional boundaries.

Option. Miscellaneous information signs may be used if they do not interfere with signing for interchanges or other critical points.

Guidance. Miscellaneous information signs should not to be installed unless there are specific reasons for orienting the travelers or identifying control points for activities that are clearly in the public interest. If Miscellaneous information signs are to be of value to the traveler, they should be consistent with other guide signs in design and legibility. On all such signs, the design should be simple and dignified, without any tendency toward flamboyant advertising and in general compliance with other signing.

903.9.4 Emergency Reference Markers (D10-5)

D10-5
D10-5

Support. Emergency Reference Markers (D10-5) are used to assist travelers in estimating their progress, provide a means for identifying the location of emergency incidents and traffic crashes, and to aid in highway maintenance and servicing.

Standard. Emergency Reference Markers (D10-5) shall be placed on Interstates (instead of traditional mile marker signs) at two tenth of a mile intervals. An Emergency Reference Marker shall not be installed if it cannot be set within 200 ft. of its exact location.

Every attempt shall be made to install Emergency Reference Markers, even if this requires special mounting designs on walls, bridges or concrete median barrier.

Emergency Reference Markers shall be vertical panels having green backgrounds with white numerals, letters and borders, except for the route shield, which shall be the standard color and shape. The top line shall consist of the cardinal direction for the roadway. The second line shall consist of the applicable route shield for the roadway. The third line shall identify the mile reference for the location and the bottom line of the Emergency Reference Marker shall give the tenth of a mile reference for the location displaying the decimal point.

Emergency Reference Markers shall have a minimum mounting height of 4 ft. to the bottom of the sign according to the mounting height requirements of EPG 903.2.26 Location Standardization and per details found in Standard Plan 903.03.

The distance numbering shall be continuous for each route within the state, except where overlaps occur (see EPG 903.8.32). Where routes overlap, Emergency Reference Marker continuity shall be established for the route of higher classification. If two routes of the same class overlap each other, the route with the lower designation takes precedent unless that route overlaps for a only short segment.

Guidance. The route selected for continuity of distance numbering should also have continuity in interchange exit numbering (see EPG 903.8.32). On a route without Emergency Reference Marker continuity, the first Emergency Reference Marker beyond the overlap should indicate the total distance traveled on the route so that travelers will have a means of correlating their travel distance between Emergency Reference Markers with that shown on their odometer.

Standard. The distance measurement shall increase in the northbound and eastbound directions of travel. Emergency Reference Markers for southbound or westbound roadways shall be set at locations directly opposite to and displaying the same distance measurement as the Emergency Reference Marker for the northbound or eastbound roadways.

Guidance. The zero-distance should begin at the south and west state lines, or at the south and west terminus points where routes begin within a state.

Standard. Except as provided in the option below Emergency Reference Markers shall be installed on the right side of the roadway.

Option. Where conditions limit or restrict the use of Emergency Reference Markers on the right side of the roadway, they may be installed in the median. Emergency Reference Markers may be installed back-to-back if the median location is warranted. Emergency Reference Markers may be installed on non-interstate freeways and expressways under the following conditions:

1. Written support from the local response agency must first be obtained.
2. A logical beginning and ending point must be chosen. Examples of logical beginning or ending points include state boundaries, transitions from two to four lanes, or major intersections. District borders, county lines or construction project limits are not logical beginning and ending points.
3. All districts along the route must be involved in the decision to install Emergency Reference Markers on a route to ensure consistency of application.

Guidance. Emergency Reference markers should not be installed on routes which are likely to change in length due to future realignments. Roadway realignments would require the replacement of Emergency Reference Markers in the future to correct the distance measurement displayed on these signs.

Support. At times individuals or groups who want historic recognition for a road or section of a road approach MoDOT. This policy defines what is needed and by whom before consideration can be given to signing an historic route.

Standard. The Commission will consider marking of an historic road when the following provisions have been met:

A. The road has been recognized by an organized federal or state group as a road having significant historical importance to the transportation system.

B. There shall be an organized group that sponsors and determines the exact route of the historical road.

C. There shall be a minimum length of 50 miles required for a historic road. Short disconnected segments are discouraged.

D. Any part of the Commission-maintained system shall be limited to a maximum of three concurrent historic route and/or trail designations.

E. There shall be an agreement between the sponsoring group and the Commission to define the responsibilities of each.

The agreement shall contain the following provisions:

A. The Commission shall coordinate the fabrication of the approved historic route signs and install and maintain these signs on the approved segments of the historic route within the Commission's current highway system.

B. The sponsoring group shall install and maintain the approved historic route signs on those portions of the approved historic route, which are not a part of the Commission's current highway system. These installations will be at no cost to the Commission.

C. The sponsoring group shall reimburse the Commission for the cost of fabricating the approved historic route signs regardless of where the signs are placed. The sponsoring group shall also reimburse the Commission for the cost of installing and maintaining those signs, which are placed on the Commission's current highway system.

D. The approved historic signs shall be mounted as an independent confirmation marker at locations agreed upon by the Commission and the sponsoring group.

If the historic road crosses a state line, there must be agreement with the adjoining state or states on the signing and the routing of the historic route. If agreements with the other states cannot be reached the historic signing shall end at the last intersection in Missouri.

If approved, Auto Tour Route signs shall not be installed on freeways or expressways, except as necessary to provide continuity between discontinuous segments of conventional roadways that are designated as auto tour routes, for which the freeway or expressway provides the only connection between the segments. If installed on freeways or expressways, Auto Tour Route signs shall be installed as independent trailblazer assemblies and shall not be installed with other Route signs or confirmation assemblies or on guide signs. If installed on freeways or expressways, Auto Tour Route trailblazer assemblies shall be installed at less frequent intervals than route confirmation assemblies.

Support. Auto Tour Route signs are informational signs, plaques, or shields designed to provide travelers with guidance in following an auto tour route of particular cultural, historical or educational significance.

Signed auto tour routes are used to generally follow the historical route of a trail. There are several approved trails or overlays that follow state maintained routes. Approved trail overlays are:

A. Lewis and Clark Trail (M17-2)

B. Great River Road (M17-6)

C. Historic 66 (M17-8, M17-8a)

D. Santa Fe Trail (M17-4)

E. Oregon Trail (M17-3)

F. Trail of Tears (M17-5)

G. Avenue of the Saints (M17-9)

H. Mississippi River Trail (MRT) or bike trail (M17-7)

I. Pony Express (M17-10)

J. California Trail (M17-11)

Standard. The State Traffic Engineer shall approve signing for any additional trails. The general principles for signing trail or overlays are:

A. Where the Trail or overlay continues over a marked route at a junction with another numbered or lettered route and no turn is involved, the Trail Route Marker shall be mounted at the lower-most portion of the confirmation assembly on the far side of the intersection. This will require a total of two markers per intersection with numbered or lettered routes.

B. Where the Trail or overlay makes a turn at a junction, there shall be a separate advance turn assembly consisting of the Trail Route Marker and Advance Turn Arrow black on white series sign beneath it. The Trail Route Marker shall be added to the confirmation assembly beyond the junction. The advance turn assembly shall be located between the junction assembly and destination sign.

C. If two or more trails or overlays run concurrently on a route, the trail or overlay confirmation assemblies shall be erected on a separate post after the route confirmation. Cardinal Direction plaques shall not be used with trails or overlay route markers. The AUTO TOUR (M17-1) auxiliary sign shall be used in combination with the Santa Fe (M17-4), Trail of Tears (M17-5), and Oregon Trail (M17-3) markers.

Guidance. If shields or other similar signs are used to provide route guidance in following an auto tour route, they should be designed in accordance with the sizes and other design principles for route signs, such as those described in EPG 903.7.10 through EPG 903.7.12.

Typically exclusive to the Lewis and Clark Trail (M17-2) marker, signing should be placed on the Advance Guide Sign where the Lewis and Clark trail crosses an expressway or freeway.

Option. The Lewis and Clark Trail marker may be placed either on the Advance Guide sign if there is adequate green space at the top of the sign or mounted to hang below the Advance Guide Sign.

Support. Acknowledgment signs are a way of recognizing a company, business, or volunteer group that provides a highway-related service. Acknowledgment signs include, but are not limited to, sponsorship signs for adopt-a-highway litter removal programs, maintenance of a parkway or interchange, and other highway maintenance or beautification sponsorship programs.

Refer to EPG 141.8 Sponsorship Programs for more information on MoDOT's Sponsorship Policy.

Guidance. Refer to EPG 171 Maintenance Policy and Operations for acknowledgment sign program policy.

Standard. Because regulatory, warning, and guide signs have a higher priority, acknowledgment signs shall only be installed where adequate spacing is available between the acknowledgment sign and other higher priority signs. Acknowledgment signs shall not be installed in a position where they would obscure the road users’ view of other traffic control devices.

Acknowledgment signs shall not be installed at any of the following locations:

A. On the front or back of, adjacent to, or around any other traffic control device, including traffic signs, highway traffic signals and changeable message signs;

B. On the front or back of, adjacent to, or around the supports or structures of other traffic control devices, or bridge piers; or

C. At key decision points where a road user’s attention is more appropriately focused on other traffic control devices, roadway geometry or traffic conditions, including exit and entrance ramps, intersections, grade crossings, toll plazas, temporary traffic control zones and areas of limited sight distance.

Guidance. The minimum spacing between acknowledgment signs and any other traffic control signs, except parking regulation signs, should be:

A. 150 ft. on roadways with speed limits of less than 30 mph,

B. 200 ft. on roadways with speed limits of 30 to 45 mph, and

C. 500 ft. on roadways with speed limits greater than 45 mph.

If the placement of a newly-installed higher-priority traffic control device, such as a higher-priority sign, a highway traffic signal or a temporary traffic control device, conflicts with an existing acknowledgment sign, the acknowledgment sign should be relocated, covered or removed.

Option. Acknowledgment signs may have their own designs and may also use their own pictograph and/or a brief jurisdiction-wide program slogan as part of any portion of the acknowledgment sign, provided that the signs comply with the provisions for shape, color, and lettering style in this article and in EPG 903.2 Extent of Signing.

Guidance. Acknowledgment signs should clearly indicate the type of highway services provided by the sponsor.

Standard. Acknowledgment signs shall comply with the following provisions:

A. Neither the sign design nor the sponsor acknowledgment logo shall contain any contact information, directions, slogans (other than a brief jurisdiction-wide program slogan, if used), telephone numbers, or internet addresses, including domain names and uniform resource locators (URL);

B. Except for the lettering, if any, on the sponsor acknowledgment logo, all of the lettering shall be in upper-case letters;

C. In order to keep the main focus on the highway-related service and not on the sponsor acknowledgment logo, the area reserved for the sponsor acknowledgment logo shall not exceed 1/3 of the total area of the sign and shall be a maximum of 8 sq. ft., and shall not be located at the top of the sign;

D. The entire sign display area shall not exceed 24 sq. ft.;

E. The sign shall not contain any messages, lights, symbols or trademarks that resemble any official traffic control devices;

F. The sign shall not contain any external or internal illumination, light-emitting diodes, luminous tubing, fiber optics, luminescent panels, or other flashing, moving or animated features; and

G. The sign shall not distract from official traffic control messages such as regulatory, warning, or guidance messages.

Guidance. In spring of 2012 the design of Adopt-A-Highway signs changed from an all blue background (I9-1) to a blue and white background with an interchangeable plaque system (I9-1a and I9-1aP). This plaque system is designed to allow Adopt-A-Highway signs to remain standing when adopters enter and leave the program. For new adoptions, the basic sign has a message of “AVAILABLE 888-ASK-MODOT” (I9-1a) and the plaque bearing the adopter’s name or message (I9-1aP) is installed over this message. When an adopter ceases participation in the program, the plaque should be removed, revealing the “available” message.

Additionally, “AVAILABLE 888-ASK-MODOT” plaques (I9-1P) may be placed on the older style signs (I9-1) when an adopter stops participating if the existing sign still has some remaining service life. Once a new adopter chooses this section of roadway, the “available” plaque (I9-1P) may be changed out with a new plaque bearing the adopters name or message (I9-1aP).

903.9.7 Airport Sign (D4-10)

D4-10
D4-10

Support. The D4-10 airport signs are intended for small public airfields or airports.

Option. The Airport (D4-10) signs may be mounted back-to-back on the same post(s) or erected separately.

Third order signing may be provided for small airports that provide limited, regularly scheduled commercial service.

Standard. First order signing shall only be provided for public airports or flying fields that do not offer commercial flights. If the first order signing location is at an interchange, only ramp terminal signing will be provided. Airport signing shall not be provided for privately owned airports or flying fields.

Use of the Airport (I-5) Symbol sign is reserved for guidance to airports offering commercial service and shall not be used to provide guidance for airports that do not provide commercial flights.

903.9.8 BUSINESS DISTRICT and INDUSTRIAL PARK Signs (D4-15, D4-16)

D4-15
D4-15
D4-16
D4-16

Option. The BUSINESS DISTRICT (D4-15) sign may be erected on a highway within the city limits at the principal intersection leading to the central business district.

Standard. If a route passes through the central business district, this sign shall not be used.

Option. The INDUSTRIAL PARK (D4-16) sign may be erected on a highway within the city limits at the principal intersection leading to the central industrial park when truck traffic tends to get lost or miss turns.

Guidance. If used, the INDUSTRIAL PARK sign should be installed at first order signing for the most direct path.

Standard. If a route passes through the industrial park, this sign shall not be used.

903.9.9 City/County Limit Signs (I4, I5, I6 Series)

I4-1
I4-1
I4-2

Standard. The City Limit (I4 series) signs shall be erected at the city limit of each incorporated area, at the point where the city limit crosses the right of way.

The population of the I4 series signs shall be according to the latest U.S. Census published by the United States Department of Commerce or in accordance with a special census by the governor.

The population shall not be shown on a Town sign.

The County Line (I6 series) signs shall be erected on all routes at county lines.

Guidance. The County Line sign should not be erected at the state line.

Support. See EPG 903.17 Typical Signing Applications of City Limit signs.

Option. The Town sign may be erected at the entrance to an unincorporated area.

A Speed Limit sign may be mounted above the Town sign.

Town Signs (I5-1) may be installed at the approximate entrance of an unincorporated town, similar to a city limit sign. Towns eligible for signing are those that the traveling public would view or recognize as an organized town as they pass through the area. These towns would typically have businesses, community centers or other non-residential structures that are visible from the highway, in addition to their residential areas. They would also be significant enough to typically justify a reduction in the posted speed limit and/or be considered as a destination on highway signs. Eligible towns are typically structured enough to also have some form of governing board or council.

Residential neighbor developments or subdivisions are not to be considered towns that would qualify for highway signing. Regions that once were recognized by the traveling public as a town but now have very little or no community recognizable features would no longer be eligible for signing. Existing Community boards installed for regions that are no longer eligible for signing shall remain in place until the end of their service life.

903.9.10 Special Supplemental Signing

Support. Special supplemental signing policies contained in EPG 903.9.11 and EPG 903.9.12 refer to signs that are either modifications of existing MoDOT signs or special guide signs that have been approved for use. In many cases these signs are provided by MoDOT and have a participation fee associated with the fabrication, installation and maintenance of these special supplementary signs.

Guidance. Care should be taken when considering adding supplemental signs to make sure they do not interfere with or distract from regulatory, warning or guide signs. Sufficient spacing, at least 800 ft. on freeways or expressways, should be allowed for drivers to be able to read and comprehend the sign messages.

903.9.11 Custom City Limit and Custom County Line Signs (I4-1a, I4-2b, I4-2c, I6-1a)

Support. Many cities and counties want to enhance their identity and presence to the traveling public. A way to do this is by placing customized city or county limit signs in lieu of the MoDOT standard sign. Standards have been developed, according to the MUTCD, as to what the signs will look like and what is allowed to be added to customize the signs. Custom signs are not required at city or county limits on the state system.

Incorporated communities are permitted to request that custom city limit signs be installed on the state system.

Standard. Any custom sign not conforming to this policy shall be removed.

MoDOT shall fabricate customized signs, for consistency, according to the standards described below. Graphics or messages requested by the city or county shall have the approval of the department prior to fabrication.

The signs shall be white legend on a green background. The signs shall be made of reflectorized material according to MoDOT standards. Lettering on the signs shall be of the approved size and style as contained in the MUTCD for the type of facility where the signs will go.

The left side of the signs shall be the standard message used on MoDOT-supplied city or county limit signs that is the wording “City Limit”, the name of the city and the population or “Entering” and name of county. The right side of the sign, in a square area, dependent on the height of the sign, shall be where the city or county will be allowed to put their custom legend. The use of a city or county logo or emblem shall be allowed. Logos of individual organizations shall not be allowed.

When a city or county elects to use a customized limit sign, MoDOT shall replace the standard sign with the custom sign. If there is a need for a speed limit sign, the speed limit sign shall be installed the same as if a standard city limit sign were used.

A participation fee shall be paid for by the city/county which will include all cost for fabrication, installation, and maintenance of the signs. Refer to EPG 903.16 for contract process.

Lighting of these signs shall not be allowed.

Guidance. The TR-15 contract should be executed between the city or county and MoDOT before the sign is installed.

The legend of the sign should be simple, dignified and void of any commercial advertising.

Landscaping around any of these signs should be coordinated and reviewed by the department’s roadside management personnel.

903.9.12 City and County Accomplishment Plaques (I4-1P, I4-2P, I5-1P, I6-1P)

Support. Many cities and counties want to announce the academic and/or athletic accomplishments of their local schools.

Option. A city may elect to recognize the academic and athletic accomplishments of their schools by placing a maximum of three supplemental plaques, 1 ft. tall, under the custom or standard city limit sign and a county may place a maximum of two supplemental plaques, 1 ft. tall under the custom or standard county line sign.

In order to accommodate legends with a sizeable amount of text, several plaques may be used for the message. See Fig. 903.9.12.

Fig. 903.9.12
Fig. 903.9.12

Standard. Supplemental plaques shall be allowed under city/county limit or custom city/county signs. The city or county shall select the accomplishments to be displayed with MoDOT’s concurrence.

One accomplishment shall be displayed on one plaque, except as provided herein.

Each plaque shall be variable by 12 in. with a maximum width of 60 in. for flat sheet and 120 in. for structural.

If a new accomplishment plaque is requested and the maximum amount already exists, the city or county shall determine which existing plaque gets removed, if any.

The plaques shall be white legend on green background. All minimum ground clearance and breakaway requirements shall be followed. No commercial advertising or business logos shall be permitted.

The participation fee shall be paid for by the city or county. Department forces shall fabricate, install and maintain these plaques.

Guidance. When several plaques are used to accommodate legends with a sizeable amount of text the sum of square footage of 3 supplemental plaques is not to be exceeded for cities and 2 supplemental plaques for counties.

903.9.13 Welcome To Signs for Cities

Option. Cities may place Welcome To signs on MoDOT right of way to welcome visitors to their city when their city limits encompass the intersection.

Welcome To signs may be made retroreflective.

"Welcome To" Sign
"Welcome To" Sign

Standard. Welcome To signs shall fit on one or two MoDOT breakaway sign posts (wood, PSST, pipe, structural) as a ground mounted sign only. Welcome To signs shall not be mounted overhead or on bridge structures, i.e. girders, columns abutment walls, etc.

Welcome To signs shall not be illuminated electrically.

Welcome To signs shall not contain advertisement of any kind.

Welcome To signs shall not provide directional guidance by displaying destinations with or without arrows.

A TR-42 agreement shall be executed before a Welcome To sign is installed.

Guidance. Welcome To signs should be installed in a location that does not interfere with normal highway signs and possess the least possible threat to the motorist should they leave the roadway.

The district should consider issuing a permit that would be tied to the installation of Welcome To signs so as to address details that are not covered in the TR-42 (such as locating utilities and traffic control responsibilities).

Support. The content and design of the sign face is up to the city. It is recommended the signs be retroreflective so they are visible at night and have the same appearance at night as they do during the day.

Guidance for Welcome To monuments can be found in EPG 941.5.

903.9.14 State Line Signs (I2-1, I2-2, I2-3, I2-3P)

I2-1
I2-1
I2-2
I2-2
I2-3
I2-3
I2-3P
I2-3P

Standard. The MISSOURI STATE LINE (I2-1) sign shall be erected at the state line on all lettered routes.

The large Welcome to Missouri (I2-3) sign shall be erected at or near the state line on numbered routes where the traffic volume is 1,000 AADT or greater. The Welcome to Missouri Welcome Center (I2-3P) plaque shall be installed below a Welcome to Missouri (I2-3) sign on interstates when there is a welcome center located downstream from the state line.

The smaller sign (I2-2) shall be erected at or near the state line on numbered routes where the traffic volume is less than 1,000 AADT.

Guidance. At locations where it may be impractical to erect the Welcome to Missouri sign at or near the state line, the MISSOURI STATE LINE sign should be used. At such locations the Welcome to Missouri sign shall be erected in addition to the MISSOURI STATE LINE sign, preferable within ¼ mile of the state line.

Option. The MISSOURI STATE LINE sign may be erected on other routes where it is impractical to use the Welcome to Missouri sign.

903.9.15 Stream Name Signs (I3-1)

I3-1
I3-1

Guidance. Stream Name (I3-1) signs should be erected at all bridge type structures, excluding box culverts, on the interstate and all numbered routes where the official name can be determined. If the name of the stream cannot be determined, the Stream Name sign should be omitted.

Standard. Stream Name signs shall not be installed on letter routes.

In those cases where signing for a body of water, which is a part of or connected to a lake, names (such as branch, river, creek, etc.) shall be incorporated in the sign as required. A typical example of this type of signing would be “LAKE OF THE OZARKS-OSAGE RIVER”.

903.9.16 Transportation Signs (I-5, I-7, E11-1)

I-5
I-5
I-7
I-7
E11-1

Option. Guide signs for commercial service airports may be provided from the nearest Interstate, or other freeway intersection directly to the airport, normally not to exceed 15 miles. The Airport (I-5) symbol sign along with a supplemental plaque may be used to indicate the specific name of the airport. An Airport symbol sign, with or without a supplemental name plaque or the word AIRPORT, and an arrow may be used as a trailblazer.
