2025 ACEC-NH & NHDOT Technical Exchange Conference

Session 14A: Dummer-Cambridge-Errol 16304B (NH 16) Design and Construction
Speaker: Tim Dunn, NHDOT; Chuck Flanders, NHDOT
- The Dummer-Cambridge-Errol 16304B project reconstructs one mile of NH Route 16 in Cambridge, NH. The project is the second of four planned in Thirteen Mile Woods, from Dummer to Errol, that when complete would allow the road to not require load posting in the spring. The project was complicated by the proximity of the Androscoggin River to the east and extensive wetlands and multiple conservation easements to the west along with challenging construction conditions. All aspects of the project’s development will be discussed from design and mitigation to ROW acquisition and construction.
