Main Street Bridge Replacement & US 202 Reconstruction, Peterborough, NH

Hoyle Tanner partnered with the Town of Peterborough and NHDOT on this federally-funded Local Public Agency (LPA) project from the Engineering Study through final design, bidding and construction phases, including the environmental permitting and NEPA processes. Replacement of the historic, but structurally deficient, Main Street Bridge over the Contoocook River in downtown Peterborough was the catalyst for this comprehensive and complex transportation project with a total construction cost of nearly $15 million that also included realignment, widening, and reconstruction of approximately 850′ of US Route 202 including both sidewalks; construction of a new stone-faced steel King-pile and sheeting retaining wall; in-situ stabilization of an historic boulder retaining wall; reconstruction of a portion of the Transcript Dam; lining of an historic granite canal; and extensive utility coordination and relocation work. As the prime consultant, Hoyle Tanner assembled and managed an extensive team of specialized subconsultants to complete the project. Close coordination with stakeholders, including the New Hampshire Division of Historical Resources and the Peterborough Heritage Commission, was required throughout the project development process.
