Ontario Highway 148

Highway 148 within Pembroke

Highway 148 connects Pembroke to the Quebec border at L'Isle-aux-Allumettes, a distance of 5 km (3.1 mi). It originally connected to Highway 17 west of Pembroke, and was 15.1 km (9.4 mi) long.[3] However, its length was truncated on April 1, 1997 when the province downloaded responsibility for the portion from Highway 17 to Boundary Street.[4] At that time, the connecting link status of Highway 148 through Pembroke itself was revised, and the current signed terminus of the highway is now Mackay Street, which was formerly Highway 41.[3][5] Approximately 11,400 vehicles drive along Highway 148 on an average day, with just under half that many crossing from or into Quebec.[1]

Provincial control of Highway 148 begins at the Pembroke boundary, approximately 60 m (200 ft) northwest of Angus Campbell Drive. From there, the route travels southeast through the urban-rural fringe of the city, passing east of two large shopping complexes. After passing west of the community of Pleasant View, the route enters a rural area and curves south alongside farmland.[6]

At a four-way stop with channelized right turn lanes, drivers must turn to remain on the highway. To the south is Renfrew County Road 40, which continues to Highway 17 at the southern end of the Pembroke Bypass. Highway 148 continues east, crossing the Ottawa Valley Railway and the entrance to Hazley Bay before entering the community of Cotnam Island. The highway curves northeast and crosses the Ottawa River, entering Quebec midspan.[6]

Highway 148 follows the route of what was the northernmost section of Highway 62, prior to the opening of the Pembroke Bypass. Highway 17 was also signed concurrently with Highway 62 between Trafalgar Road and Renfrew County Road 40, as it followed the Ottawa River in the Pembroke area at that time.[7] On September 10, 1982, the Pembroke Bypass was ceremoniously opened to traffic, diverting Highway 17 to the west.[2][8] In the process, Highway 62 was truncated at the new bypass; the removed section was redesignated Highway 148, giving it the same number as the route in Quebec that it served to connect with the Trans-Canada Highway.[9] Highway 148 was 14.4 km (8.9 mi) long. However, its length was truncated on April 1, 1997 when the province downloaded responsibility for the portions between Highway 17 and Highway 41 to the Town of Pembroke and County of Renfrew.[4] The Pembroke Connecting Link agreement shares the responsibility for Highway 41 northeast of Highway 17 and for Highway 148 from Highway 41 to Cedar Lane between the province and the town.[10]
