Route 389 links the city of Baie-Comeau and the Newfoundland-Labrador border over 570 kilometres. The road was built in several steps by various contractors. It has a very uneven, winding profile that needs several corrections. The entire improvement program for route 389 between Fermont and Baie-Comeau chiefly aims to improve road safety for all users while promoting the development of northern Québec.
