New York Avenue

Delon Hampton & Associates provided full construction management and inspection services on this $25 million project. Work under this contract consisted of the demolition of portions of the existing superstructure and substructure, the reconstruction and widening of two bridges (Bridges 242 and 563), and approximately one-mile of roadway from the DC-Maryland State line to Bladensburg Road, a major entrance corridor into the District. The work to the bridges included removal and disposal of existing sidewalks, parapet walls/railings on each side of the superstructure, deteriorated concrete and asphalt from the existing rigid frames in both the eastbound and westbound lanes, and replacement with micro-silica concrete overlay. The bridge widening involved the construction of reinforced concrete rigid frames, piers, abutments, wingwalls, pile foundations, approach slabs, parapet walls, railings, and a single slope concrete barrier in the median.

Extensive and effective maintenance of traffic and close coordination with tenants adjacent to the site was required to mitigate impacts to the traveling public on this major commuter corridor.
