The populous Fraser Valley and Lower Mainland is linked to the rest of the province by Highway 1 (Fraser Canyon Highway), Highway 5 (Coquihalla Freeway), Highway 3 (Crowsnest Highway) and Highway 99 (Sea to Sky Highway). The Lower Mainland is also connected to the U.S by four highway border crossings with the Peace Arch on Interstate 5 being the largest. Several freeways connect lower mainland communities together.
