1. US Route 1 Bypass of Portsmouth NH 1940 Marker

Inscription.
The Bypass was part of a major New Deal project to move U.S. Route 1 traffic away from the congested streets of downtown Portsmouth. The Bypass created a second Piscataqua River crossing into Maine via the Interstate (Sarah M. Long) Bridge. The highway’s wide divided lanes and grade separations were the first in the state, earning it the title "New Hampshire’s Most Modern Highway." Today, the U.S. Route 1 Bypass is one of the oldest signed bypasses in the country’s numbered route system.

Erected 2013 by New Hampshire Division of Historical Resources. (Marker Number 234.)
