Rehabilitation of Parkway Bridge

Using the Federal Highway Administration as the procuring agency, the Goddard Space Flight Center entered into a contract with Martins Construction Corporation on January 18, 2003, for the rehabilitation of the bridge and ramps to the Baltimore-Washington Parkway (Rt 295). Work on this contract will begin shortly, and should be complete in approximately 18 months. During construction, the bridge will remain in service, although lanes will be narrowed and moderated at times. Employees passing over the bridge by exiting from or to the southbound Parkway are encouraged to use alternative entrances. The Facilities Management Division will continue to provide updates to the Goddard community at http://gsfc-artemis.gsfc.nasa.gov/220/fmdproj.html.

The bridge was originally built in 1966 and needs a major restoration to extend its useful life. This contract marks the first major repair of the bridge in its 37year life. The project includes the complete removal and replacement of the concrete deck and parapet sidewalls across the 177 meter length of the bridge; removal of the paint for the supporting steel girders and beams and repainting; repairing the concrete piers that support the steel girders; and miscellaneous work at each abutment and approach.
