Highway 20, also known as the Chilcotin Highway, and officially dubbed the Alexander MacKenzie Highway, is one of the two main East-West routes in the Central Interior of British Columbia (the other being Highway 16 (the Yellowhead Highway)). The Chilcotin Highway runs 457 km (284 mi) from Williams Lake westward through the Chilcotin region to North Bentinck Arm, an inlet from the Pacific Ocean where the town of Bella Coola is located. As of 2006, all but 57 km (35 mi) has been paved, mostly for expediting the removal of timber from the region, which, like most of British Columbia, is afflicted with pine beetle infestations. Logging traffic and ranch-related traffic on the route can be expected.
