The structural and operational characteristics of all highway bridge and tunnel structures should be preserved as near as practical to the originally constructed or subsequently modified conditions.

The area below bridges and within tunnels or near their openings (portals) should be maintained free of flammable or explosive material. Flammable materials may include any number of items including construction materials and homeless encampments. Fuel tanks and cylinders of compressed gases should not be stored within 100 feet of a bridge or tunnel.

Maintaining bridge joints, keeping debris from accumulating around bearing devices, and addressing issues with drainage to prevent undermining of approaches and slope protection is critical. Such objectives are accomplished by timely performance of preventive maintenance and repair as determined by constant alertness and deliberate inspection.

Documentation of all work performed on a bridge is to be provided to the district bridge inspection coordinator to ensure all relevant information regarding bridge maintenance is retained and uploaded to AssetWise for each structure worked on.

Documentation includes what work was done, when it was completed, who performed the work (contract or in-house), and the cost.

Include photos of the completed work to help with the documentation. The district bridge inspection coordinator will add all documentation provided to the permanent bridge record for each bridge.
