Learn More



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.

The next phase of this project will consist of bridge demolishing utilizing cranes. This work will begin on March 10, 2018 and extend through March 23, 2018, weather permitting.

Since it is completely unsafe to perform bridge demolition when CSX and Metro trains are running, DDOT’s contractor must demolish the bridge during night hours. Demolition will begin on Saturday, March 10th between the hours of 7 AM to 7 PM. During the period of Monday, March 12th to Friday, March 23rd, demolition will take place from 12 AM to 5 AM. During these times, only one lane of traffic will be open over Monroe Street Bridge; and during lifting of existing girders, there will be a complete road closure at the bridge for 15-minute intervals. DDOT will provide detours and there will be flaggers on both sides of 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 when traveling through this area.

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.


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.
