PROJECT BACKGROUND
The Monroe Street Bridge is a three-span prestressed concrete bridge supported by two concrete abutments and two reinforced concrete piers, all supported by shallow foundations. The bridge struc-ture carries Monroe Street NE over the Washington Metropolitan Area Transit Authority (WMATA) and CSX tracks as well as the Brookland-CUA Metro platform. The existing bridge is approximately 122 feet long and 66 feet wide.
The existing Monroe Street Bridge was built in 1931 and underwent a major rehabilitation in 1974. However the bridge’s deteriorated condition is such that it must be reconstructed rather than be repaired. The proposed design solution for reconstructing the bridge involves replacement of the aging and severely deteriorated superstructure with a new superstructure as well as rehabilitation of the existing substructure.
