| − | ===Performance Expectation===
| |
| − | Mainline bridge deck and approach slabs shall be maintained to provide a smooth riding transition from one pavement segment to the next.
| |
| − | | |
| − | ===Performance Measures===
| |
| − | Randomly selected mainline bridge deck and approach slabs will be annually measured in the fall with the ARAN van to determine the average IRI. Visual inspections will be conducted on the same bridges in the spring to determine the deck rating and percent repaired surface area.
| |
| − | | |
| − | ===Performance Objectives===
| |
| − | Mainline bridge deck and approach slabs shall have an average IRI of less than 140 within 0.1 miles of the bridge, a deck rating of at least 6 and no more than 10% visible patching by surface area.

| − | ===Performance Expectation===
| |
| − | Superstructure elements of overpass bridges shall be in good repair with an acceptable aesthetic appearance and superstructure elements of mainline bridges shall be in good condition.
| |
| − | | |
| − | ===Performance Measures===
| |
| − | Visual inspections will be conducted on randomly selected mainline bridges and overpass bridges located within the roadway segment in the spring to identify exposed reinforcing steel, loose concrete and graffiti visible from the interstate roadway. Visual inspections will be conducted on all mainline and overpass bridges in the fall to determine the superstructure rating and paint condition.
| |
| − | | |
| − | ===Performance Objectives===
| |
| − | Mainline bridges and overpass bridges shall be free of visible exposed reinforcing steel, loose concrete and graffiti. Mainline bridges shall have a superstructure rating of at least 5. Mainline bridges and overpass bridges shall have a paint rating of at least fair. Graffiti shall be removed within 30 days of detection.

| − | ===Performance Expectation===
| |
| − | Slope protection shall be maintained in order to prevent the spill fills of the structure from eroding and to provide protection from undermining of the bridge abutments.
| |
| − | | |
| − | ===Performance Measures===
| |
| − | Visual inspections will be conducted on randomly selected mainline bridges and overpass bridges located within the roadway segment in the spring to determine if the slope protection on the bridge looks good and is performing as intended.
| |
| − | | |
| − | ===Performance Objectives===
| |
| − | 90% of the concrete slope protection shall be structurally sound without any broken or misaligned slabs. 100% of slope protection visible from mainline shall be free of vegetation.
