State Route 236, also known as the Harold L. Dow Highway, is a 15.8-mile (25.4 km) long state highway in southwestern Maine. It runs from an intersection with State Route 103 in Kittery to an intersection with State Route 9 in Berwick, just east of the border with New Hampshire. SR 236 is signed as a north-south route, but follows a roughly southeast-to-northwest alignment.
The southern terminus of SR 236 is at the intersection of Whipple Road (SR 103), Woodlawn Avenue, and Shapleigh Road in Kittery, near the main entrance to the Portsmouth Naval Shipyard. It follows Shapleigh Road, then Rogers Road, to the Kittery Traffic Circle, where it connects to U.S. Route 1, US 1 Bypass, and Old Post Road. The rotary marks the beginning of the Dow Highway. Passing under US 1 Bypass and over Interstate 95, the route heads along the former right-of-way of the B&M Railroad until a T-intersection with SR 4 in South Berwick, the end of the Dow Highway. Route 236 runs briefly with Route 4 through downtown South Berwick, then splits off to follow Berwick Road into downtown Berwick, along Allen St to its northern terminus at SR 9 near the New Hampshire state line. Less than a quarter mile west, SR 9 crosses into Somersworth, New Hampshire and becomes New Hampshire Routes 9 and 236.
NH 236, which terminates at the state border, is effectively a westward extension of SR 236 through downtown Somersworth which connects to NH 108 south of Rochester. Though it does not directly connect to SR 236, the two routes are connected via SR 9.
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. Interestingly, both SR 103 and SR 236 have a terminus at the other route.
Most of the southern part of the route, 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. While railroad service has disappeared, SR 236 is a service corridor for commuter bus service to the Portsmouth Naval Shipyard in Kittery and Market Square in Portsmouth.
The entire route is in York County.
