Historic Stone Arch Bridge Rehabilitation
Historic Stone Arch Bridge Rehabilitation
The Hillsborough Stone Arch bridge, also known as Sawyer Bridge, was built in 1866 by Rueben Loverin. The bridge carried US Route 202 until 1988 when it was bypassed with a new bridge upstream. As part of the new bridge construction, the third span of the bridge was removed due to its poor condition and to improve hydraulics in the area. After years of little use, the bridge was in need of a rehabilitation as it was experiencing bulging and leaning of its parapet walls.
Hoyle Tanner provided full inspection, rehabilitation design and construction phase services for this historic bridge. The bridge pavement and part of the roadway fill was removed and a buried membrane and drainage system installed to collect water and direct it away from the arches and parapets. Each bridge parapet was then partially reconstructed and a new pedestrian railing installed. Hoyle Tanner provided near full-time inspection and construction administration for this project which was partially funded by Transportation Enhancement and ARRA-related funding.
