Project Background

In 2011 the Rockingham Planning Commission (RPC), on behalf of the Town of Plaistow, performed a Traffic Calming Study for Main Street (NH Route 121A) which recommended the implementation of a comprehensive traffic calming program along Main Street, from the Library/Bittersweet Drive north to Dunston Avenue. As defined by the Federal Highway Administration, the primary purpose of traffic calming is to support the livability and vitality of residential and commercial areas through improvements in non-motorist safety, mobility, and comfort.


In 2021, the New Hampshire Department of Transportation (NHDOT) in partnership with the Town and the RPC conducted an online survey to better understand the issues and priorities that currently exist along Main Street. The information collected has assisted in the development of traffic calming measures that could be implemented throughout the corridor to slow traffic, discourage heavy vehicles cutting through, and improve mobility for non-motorized travel, with the ultimate goal of improving the safety along Main Street.


NHDOT has developed a project page in their Project Information Center where you can find additional project details, available files, and schedule information. Visit to learn more about this project.
