Permanent Work to restore bridges is eligible unless restoration is under the specific authority of another Federal Agency such as the Federal Highway Administration.

Work to repair scour or erosion damage to a channel or stream bank is eligible if the repair is necessary to restore the structural integrity of an eligible road, culvert, or bridge.

Hydrologic and hydraulic studies, used to evaluate upstream and downstream impacts, may be necessary if replacing culverts or bridges with larger culverts or bridges.
