McMahon provided traffic analysis and design services through construction of the roadway improvements on High Plain Street (Route 27) and intersection modifications at Boston Providence Highway (Route 1) and the Walmart site driveway. Proposed modifications included roadway widening to accommodate an exclusive left-turn lane for the westbound approach at Boston Providence Highway (Route 1) and the eastbound approach at the Walmart site driveway. Proposed intersection improvements also included the installation of a fully actuated traffic signal at the High Plain Street (Route 27)/Walmart site driveway intersection. McMahon completed a Functional Design Report and concept design, subsequently leading the preliminary and final roadway and intersection improvement design. We also prepared the construction plans and contract documents. As part of the project a road safety audit was completed with attendees from the Town of Walpole, MassDOT and other agencies.
