Project Updates
Summer 2022 Project Update
Final design of the first construction project, the 13065A project, Exit 4A Interchange and Old Rum Trail, commenced in the spring of 2021. Design of the new interchange advanced rapidly, and the ROW acquisition process was progressed concurrently. Design was completed in April of 2022 and the project was advertised for construction bids. Weaver Brothers Construction Company, of Bow NH, was the low bidder with a bid of $45.5M. Construction is expected to begin in Summer 2022, with Construction anticipated to be complete in Fall of 2024. The total project cost is $61.6M, which includes design, construction oversight, environmental mitigation ($3.9M), and utility relocations ($2.1M).
Design was also completed on the 13065D project for the demolition of buildings on 7 NHDOT owned parcels. This project was advertised in January 2022 with demolitions expected to be completed during the Summer of 2022. Spears Brothers Building Salvage and Wrecking was the low bidder with a bid of $322,000. The total project cost is $350,000 which includes construction oversight. Once these buildings are removed, construction of the interchange can advance more rapidly. A similar project, 13065E, will demolish additional buildings on 3 other NHDOT owned parcels, which is expected to be completed late 2023 to prepare for construction of the middle construction project, 13065B.
Final design of the middle construction project, 13065B, continues to advance. In February 2022 the 60% design milestone was reached. This milestone is referred to as the Slope and Drain Submittal – meaning the slope impacts are set, the traffic control plan is finalized, and drainage design is substantially complete. This milestone begins the ROW Plan phase for the approximately 65 impacted parcels associated with this project. This project is expected to be advertised in Fall 2023 with construction beginning early in 2024 as the interchange project construction nears completion.
The third and final major construction project, 13065C, is in the early stages of final design. The design schedule is set to follow the ROW acquisition schedule for the corridor. This project is expected to advertise in early 2025.
