Monroe Street Bridge, NE
Reconstruction of Monroe Street NE Bridge
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.
As presented in the public meeting held on June 4, 2018, although there will not be a long-term full bridge closure in coordination with the 45-day WMATA shut-down, it may be necessary to have periodic short-term daytime and overnight bridge closures to complete specific construction activities.
Traffic advisories will be posted on the website and shared with the community when these closures occur. 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.
We realize that closures and the noise levels during demolition and reconstruction can cause some inconvenience to the neighboring community, and we sincerely apologize for this inconvenience. The project team is working to complete this project as quickly and as safely as possible and we thank you for your patience and understanding, as we reconstruct a safer 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.
ANTICIPATED CONSTRUCTION SCHEDULE
Project Start: End of July/early August 2017
Due to scheduling conflicts with WMATA and CSX, the current completion date has not been finalized. DDOT is currently working to resolve these scheduling conflicts and provide an updated completion date. This information will be provided here as soon as possible. DDOT thanks you for your patience as we reconstruct a safer Monroe Street NE Bridge.
