New Hampshire DOT Spaulding Turnpike Open Road Tolling
HMMH is performing noise analyses for the conversion of two toll plazas on New Hampshire's Spaulding Turnpike (Route 16) to high-speed Open Road Tolling (ORT). Located in Dover and Rochester, the existing toll plazas will remain in operation while new ORT plazas are constructed at a new location along the Turnpike nearby. HMMH is conducting a full noise impact analysis and will evaluate existing and future noise conditions based on traffic projections and proposed roadway changes. Where future noise impact is predicted, we will determine whether noise abatement by barriers would be feasible and reasonable.
