Reconstruction of

Monroe Street Bridge, NE

IMPORTANT UPDATE

The District Department of Transportation (DDOT) would like to extend its appreciation for your patience and understanding, while we continue working on the Reconstruction of the Monroe Street Bridge over WMATA & CSX tracks. As part of this project, DDOT will demolish the existing three span Monroe Street Bridge, and will construct a new three span bridge, including the associated roadway improvement. This reconstruction project is necessary to eliminate the existing bridge conditions deficiencies and increase safety for vehicles, bicyclists and pedestrians using the bridge.

Since it is completely unsafe to perform bridge demolition when CSX and Metro trains are running, DDOT’s contractor may be doing work during the hours of 12 AM to 5 AM. During these times when work is being done, the bridge may be closed to traffic.  Detours will be provided and there will be flaggers at the bridge to direct vehicles, bicyclists and pedestrians safely through the construction zone. DDOT encourages all to stay alert and obey flaggers and construction signage.

Unfortunately, during the demolition phase of this project, this work can be a little noisy. We realize this may cause some inconvenience to the neighboring community, and we sincerely apologize for the noise levels. The project team is working to minimize the noise level as much as possible, and to complete the demolition phase as quickly and as safely as possible.

Thank you again for your patience and understanding, as we reconstruct a safer Monroe Street NE Bridge.

Reconstruction of Monroe Street NE Bridge

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 structure 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.

This project involves the reconstruction of the existing three-span Monroe Street NE concrete bridge over CSX Railroad tracks, WMATA tracks and Brookland-CUA Metro Station and associated roadway improvement. The aging and severely deteriorated superstructure will be replaced with a new superstructure. The top portion of the piers above the crash wall will be removed and reconstructed. The existing approach slabs will be removed and reconstructed.


PROJECT LIMITS

The project limits extend along Monroe Street from 7th Street to 10th Street. The majority of construction will take place between 8th and 9th Streets where the bridge spans the WMATA and CSX tracks. The new bridge will be a three-span steel superstructure.
