About this Project

The Town of Merrimack retained FST in a partnership agreement with the Nashua Regional Planning Commission (NRPC) to develop a Roadway Infrastructure Master Plan. The Plan provides a short- and long-term guide to the Town in anticipating and accommodating growth in a way that maintains an acceptable quality of life for Merrimack residents and visitors alike.

The Plan identifies Merrimack’s existing and future roadway infrastructure problem areas and potential solutions to these problems. Short and Long Range infrastructure phasing forecasts were conducted by NRPC and evaluated by FST highlighting years 2017 and 2027. Combinations of public and private infrastructure investments are assumed to fund conceptual solutions.
FST’s summarized potential short- and long-range improvement strategies. In cooperation with NRPC and the Town, FST analyzed traffic operations for the two forecast years. By 2027, overall traffic volumes will, be as much as 63-65% higher than they were in 2007. New development and increases in population and regional travel through Merrimack, primarily on the arterial systems of FE Everett Turnpike and the DWH, is expected to spur this growth.

Owner: Nashua Regional Planning Commission

Location: Merrimack, NH

Highlights: Because much of DWH through Merrimack is under the jurisdiction of NHDOT, the DWH needs to continue accommodate through traffic to the maximum extent possible, while concurrently accommodating access to abutting properties, including those where redevelopment or development is contemplated. FST recommended that the Town work closely with NHDOT and with development property owners adjacent to DWH to consolidate their driveway access demands with new parallel service/distribution roads providing access to existing traffic signals on both sides of DWH where it makes sense to do so.
