Clark Pond Road Bridge
The Clark Pond Road Bridge in Haverhill, New Hampshire, which consisted of a 9-foot diameter sliplined culvert, was damaged and subsequently closed as a result of severe storms in October 2017. Shortly thereafter, HEB Engineers began working with the Town of Haverhill to procure and utilize FEMA Public Assistance Hazard Mitigation and NHDOT State Bridge Aid funding. In addition, HEB recognized the opportunity to complement dam removal and fish passage restoration work upstream by working with the Connecticut River Conservancy to incorporate additional stream restoration components.
While assisting the Town in its generation of funding for the project, HEB began existing-features analysis including topographic survey, geotechnical investigations, hydrologic/hydraulic assessment, and an engineering study. This information provided the Town with valuable decision-making criteria such as project cost, complexity, and permitting considerations for multiple culvert replacement alternatives. Design was then carried out for a successful NHDES Wetlands Permit application.
With funding received, and design and permitting complete, HEB produced necessary construction documents and also assisted with the public bidding process. Construction of the new Clark Pond Road Bridge was completed in the fall of 2020. HEB Engineers provided Construction Administration services to ensure quality implementation of the project documents. Ultimately, the Town’s share of the project was 5% after the federal and state reimbursements.
