See [[:Category:235_Preliminary_Plans#235.8_Airports\| EPG 235.8 Airports]] for determining whether an improvement must be filed with the FAA.

	~~The notice and submittal requirements of Federal Aviation Regulation Part 77 shall be followed if any highway~~ improvement is located near an airport. Notice criteria can be found online at [http://www.faa.gov/airports_airtraffic/airports/regional_guidance/central/construction/part77/#who http://www.faa.gov/airports_airtraffic/airports/regional_guidance/central/construction/part77/#who]. Highway improvements located near airports shall also be ~~coordinated~~ with the ~~Aviation Section in Multimodal Operations. The airspace filings can be submitted electronically through FAA’s website at https://oeaaa.faa.gov/oeaaaEXT/portal.jsp.~~

	Particular attention is given to all types of signs, light poles, cranes, and large equipment that may require notice as outlined in F.A.R. Part 77. The names and locations of civil and private airports in Missouri can be obtained from the "Missouri Aeronautical Chart" available from the Aviation Section in Multimodal Operations.

	Although 1R and 2R projects are eligible for federal funding, no conceptual study report is required. However, since there may be no additional activity in the project area for a number of years, the preventive maintenance project core team should audit the corridor to identify any safety concerns involving alignment, intersection sight distance ~~and~~ roadside obstacles.

However, since there may be no additional activity in the project area for a number of years, the preventive maintenance project core team should audit the corridor to identify any safety concerns involving alignment, intersection sight distance, roadside obstacles, and other concerns outlined in SAFER. The findings of the project core team should be documented but need not be in a formal report.

	If a safety concern is identified during the corridor audit, then the safety concern should be addressed if the project budget and scope can reasonably accommodate it. During the scoping of 1R and 2R projects, in evaluating whether a physical condition constitutes a safety concern, the designer should consider guidance provided in the ''Roadside Design Guide'' (RDG), if any, and the site specific characteristics of the roadway at issue, including the location of the object or area in relation to the roadway, traffic volume, traffic speed, geometry, and the crash history (including severity) involving the roadside object or area.
