Abstract:

As a part of the Highways for LIFE initiative, the Federal Highway Administration provided a grant of $104,000 in support of the District of Columbia Department of Transportation (DDOT) project to replace the 27th Street, NW Bridge over the Broad Branch Stream. The existing substructure was constructed before 1950 and is structurally deficient, as indicated by the current structural rating of 2 based on the National Bridge Inventory (NBI). In addition, the existing bridge does not meet the current standards for lane and shoulder widths. The key innovation on the project was the use of a geosynthetic reinforced soil-integrated bridge system (GRS-IBS) for the construction of the bridge abutments. This is DDOT’s first GRS-IBS project. The construction for this project began on July 20, 2015, and the existing bridge is currently being demolished.
