The numbered roads in Kawartha Lakes account for 907.3 kilometres (563.8 mi) of roads in the Canadian province of Ontario. These roads include King's Highways that are signed and maintained by the province, as well as the city roads under the jurisdiction of the city. The 49 numbered highways provide year-round access to the mostly rural single-tier municipality of Kawartha Lakes. The longest of these roads is Highway 35, which stretches 86.7 kilometres (53.9 mi) across the municipality from the south to the north. The shortest numbered road is Kawartha Lakes Road 3, Hartley Road, a causeway just less than a kilometre long crossing Mitchell Lake. As in the rest of Ontario, the provincially maintained highways in Kawartha Lakes are designated with a shield-shaped sign topped with a crown (example pictured). These signs are known as shields, but may be referred to as reassurance markers. Highway 7, which is part of the Trans-Canada Highway, is also marked with a green maple leaf shield. (Full list...)
