Route description

The southern terminus of SR 236 is at the intersection of SR 103 (Whipple Road), Woodlawn Avenue, and Shapleigh Road in Kittery, near the Portsmouth Naval Shipyard. It follows Shapleigh Road and Rogers Road to the Kittery Traffic Circle, where it connects to US 1, US 1 Bypass, and Old Post Road. The rotary marks the southern end of the Dow Highway. SR 236 has partial interchanges with US 1 Bypass and I-95, then continues northwest along the former right-of-way of the B&M Railroad until intersecting SR 4 in South Berwick at the northern end of the Dow Highway. SR 236 is cosigned with SR 4 in downtown South Berwick, then splits off to follow Berwick Road into downtown Berwick along Allen Street to its northern terminus at SR 9 (School Street), approximately 1,200 feet (370 m) east of the New Hampshire state line. To the west, SR 9 crosses the Salmon Falls River into Somersworth, New Hampshire and continues west as NH 9 / NH 236.

NH 236 (which terminates at the state border) is a westward extension of SR 236 through downtown Somersworth to NH 108 south of Rochester. Though it does not directly connect to SR 236 as signed, the two routes are connected by SR 9.

History

The northern section of SR 236, from Gould's Corner (near SR 103 and SR 101) in Eliot to downtown Berwick, was originally designated in 1929 as part of SR 103. That route was truncated to its current terminus in 1957, and its northern segment was re-designated as SR 236. Both SR 103 and SR 236 have a terminus at the other route. Most of the southern part of SR 236 between I-95 in Kittery and SR 91 in South Berwick was built in 1956 on the former right-of-way of the B&M Railroad after service was discontinued and the tracks removed four years earlier.[2] While railroad service has disappeared, SR 236 is a busy commuter corridor connecting to I-95, the Portsmouth Naval Shipyard, and downtown Portsmouth.[3]
