King's Highway 135, commonly referred to as Highway 135, was a provincially maintained highway in the Canadian province of Ontario on the southern edge of London, following Exeter Road, which it is better known as. The road's main purpose was to link Highway 401 in London with Highway 2 in Lambeth, at a time when the London-area section of Highway 401 was only completed to the interchange with Highway 4 (Colonel Talbot Road).
