NH 132 serves as a local route closely paralleling I-93 for its entire length. This is a role usually held by US 3, however in the Lakes Region, US 3 takes a more easterly route and deviates some distance from I-93.
The route's southern terminus is at NH 9 in Concord and is known locally as East Side Drive. In East Concord village, a traffic circle provides access to Shawmut Street, West Portsmouth Street, and I-93, while NH 132 exits the traffic circle on Mountain Road. Near the northern boundary of Concord, Hoit Road provides access to I-93 and US 4. Entering Canterbury the local name changes to Southwest Road, and then at Center Road (which provides access to the Canterbury town center) changes again to Northwest Road. Entering Northfield the local name becomes Concord Road, and NH 132 crosses under I-93 without interchanging. Closely paralleling the southbound lanes of I-93, it crosses under it again without an interchange, doubles back over the freeway, and has a half interchange with it just south of the twin villages of Tilton Northfield. Here the local name changes to Park Street, and after crossing a bridge over the Winnipesaukee River and entering the town of Tilton, it immediately joins US 3 along Main Street. Another interchange with I-93 occurs in the main commercial district of Tilton, and immediately after the interchange, NH 132 leaves its concurrency with US 3 to turn northbound along Sanborn Road entering the town of Sanbornton.
After passing the main village of Sanbornton, NH 127 has its eastern terminus at NH 132 in the village of Gaza, at which point the name changes to Stage Road. Passing between I-93 and Hermit Lake, NH 132 crosses under the freeway again briefly entering the town of Meredith before entering New Hampton without intersecting any other roads. Intersecting with NH 104 near New Hampton School, NH 132 merges with NH 104 and goes east to have another interchange with I-93. Just east of the interchange, NH 132 leaves the concurrency and turns north on an unnamed road. NH 132 passes under I-93 twice more before leaving New Hampton and entering Ashland, just south of the main village of that town. In Ashland, the route follows Depot Street before reaching its northern terminus at US 3/NH 25 (Daniel Webster Highway) at the center of the village.
History
This section needs expansion. You can help by adding to it. (June 2012)
NH 132 was once known as New Hampshire Route 3B, a designation derived from U.S. Route 3, as there is no state route numbered "3" in New Hampshire. The Route 3B designation was in use circa 1941 through 1971, per newspapers of the era.[2][3]
