Project Description

These projects improvement of bridges and the rehabilitation of retaining walls at various locations on the Rock island District to prevent structural issues. Project funds proactively address deterioration that can result in the destabilization of the roadbed, track shifting, and slow orders. Bridge improvements may include but are not limited to the rehabilitation of wing walls, addressing cracked bearing blocks, renewing bridge seats on abutments, and protective coating. Project funds may be used for engineering design services, installation of outer-track fencing, the addition of concrete panels or bin walls, or reconstruction of retaining wall sections with steel sheet piling as needed. Specific improvements will be determined based on a survey of field conditions.
