The Federal Highway Administration, Eastern Federal Lands Highway Division (EFLHD) as the representative for the owner, the District of Columbia, District Department of Transportation (DDOT), selected Cherry Hill Construction, Inc. (CHC) and Johnson, Mirmiran & Thompson (JMT) for this challenging design/build project in the northeastern portion of Washington, D.C. in Ward 5. The project consists of the demolition of and removal of the existing structure and the design and replacement of the 9th Street Bridge over New York Avenue, Amtrak & CSXT Rail Facilities. The existing bridge is a seven-span structure originally constructed in 1941. The bridge carries four lanes of traffic, minimal width sidewalks and ramp structures to and from New York Avenue. The new 9th Street Bridge will be a four span 643 foot long steel plate girder structure. The new bridge will also carry four lanes of traffic and provide two 9 foot wide sidewalks. The Aesthetic features include granite faced curbs, new brick medians along New York Avenue, ornamental light poles and fixtures, fencing and railings, landscaping and a running bond finish on bridge wing-walls. Additional work includes the reconstruction and widening of New York Avenue from Fairview Avenue to just east of the existing 9th Street Bridge, realignment of the 9th Street Intersection with T Street, newly configured intersection at the 9th Street-Brentwood Parkway-Mount Olivet Road Intersection and minor approach work along Mount Olivet Road and Brentwood Parkway.
