King's Highway 148, commonly referred to as Highway 148, is a provincially maintained highway in Ontario, Canada. The highway acts as an extension of Route 148 in Quebec, once connecting it with Highway 17, the Trans-Canada Highway, near Pembroke. It was shortened to its present terminus in 1997, and now connects downtown Pembroke to the provincial border. Highway 148 follows a route that was once part of Highway 17 and Highway 62 until the Pembroke Bypass opened in 1982.
