This intersection that connects New Hampshire and Maine between Conway, New Hampshire and Fryeburg, Maine is ranked as a high-crash location. Utilizing Highway Safety Improvement Program (HSIP) funding, NHDOT partnered with Hoyle Tanner to make improvements to the intersection improve safety and reduce crashes. With a consideration for available Right-of-Way, environmental impacts, and project cost, our team helped NHDOT determine which alternative best improved safety while minimizing delay along the corridor. Two significant challenges were identified during preliminary NEPA review: a historically contaminated site on the northeast corner of the intersection that will need further soil and water sampling should there be impacts near that area; and the presence of a stone marker identifying the original location of the Town’s burial ground, which prompted the need for a Phase IA and IB archaeologic assessment that included Ground Penetrating Radar (GPR) to clear the area of any human remains from the relocation of the cemetery in the early 1950s – this is only the second time GPR has been used on a NHDOT project in New Hampshire. Hoyle Tanner’s highly professional coordination between NHDHR, NHDOT, the Town and the subconsultants was instrumental is making sure these efforts proceeded in a manner that allowed the project to remain on schedule and within budget.
