King's Highway 138, commonly referred to as Highway 138, is a provincially maintained highway in eastern Ontario. It extends from the former Highway 2 in Cornwall, north to Highway 417 east of Casselman. Highway 138 provides access to the Seaway International Bridge, connecting Cornwall with Massena, New York. The highway is 38.7 km (24.0 mi) in length.

Highway 138 was first established in 1967, connecting Highway 2, now Vincent Massey Drive, with Highway 43 in Monkland. By the mid-1970s, the route had been extended north to meet with the newly opened Highway 417. Since then it has remained unchanged.

Route description

Highway 138 through St. Andrews West.

Highway 138 is a 36.0-kilometre (22.4 mi) highway that crosses the Laurentian Valley in eastern Ontario, connecting Highway 401 in Cornwall with Highway 417 east of Casselman.^[3]

The route begins at 9th Street West, which was Highway 2 until the late 90s, and proceeds north along the western side of Cornwall; this section is maintained under a Connecting Link agreement and is locally known as Brookdale Avenue.^[4] After crossing Highway 401, at which there is an interchange, the route encounters Cornwall Centre Road, onto which it turns east. After following it for a brief distance, the highway turns north onto St. Andrews Road; the Connecting Link agreement ends at this junction.^[4]

Over the next two kilometres (1.25 mi), the highway exits the fringes of Cornwall, passing through the neighbourhood of Churchill Heights. After passing Headline Road (County Road 44), the route divides a forest and then enters an agricultural area before coming upon the community of St. Andrews West. It crosses the Raisin River and continues north through a mix of farmland and forests.

History

Highway 138 was established by the Department of Highways on May 1, 1967, following existing Stormont County roads between Highway 2 at the Seaway International Bridge and Highway 43.^[1] With the construction of Highway 417 planned and progressing eastward from Ottawa, Highway 138 was extended north to its present terminus east of Casselman in 1971 or 1972.^[5][6] Its route remained unchanged from then until the mass downloading of highways, during which the southern end was truncated to Highway 401.

Major intersections

The entirety of Highway 138 is located in Stormont, Dundas and Glengarry United Counties.^[3]
