SNZP/Rock Creek Harvard Street Bridge Rehabilitation & Repairs

Located just upstream of the Old Harvard Street bridge, the New Harvard Street Bridge was completed in 1965 at a cost of approximately $307,000. Designed by the Bureau of Public Roads and National Park Service, this bridge was one of the few bridges of its type in the world; its structure is a concrete box girder with a trapezoidal section and sides angling down.

Though the span does not conform to the appearance of other park bridges, its design continues the tradition of experimentation and engineering firsts in national park road construction. Both the abutments and the deck needed extensive repairs including waterproofing. All work was performed in accordance with the District of Columbia Department of Transportation requirements.
