This Accelerated Bridge Construction (ABC) Design Build project in Durham, New Hampshire consisted of the replacement of an existing 15’ concrete slab bridge built in 1933 on Route 4 over Bunker Creek. Route 4 is one of two major East-West corridors in New Hampshire and carries 17,000 vehicles per day, so it was imperative to limit the impact to the public. Further to these challenges, the existing roadway consists of a causeway through a tidal marsh which the design-build team, consisting of SPS New England Inc. as the contractor and WSP USA Inc. as the designer, was tasked with ensuring that minimal future settlement would not occur.
