Quebec provincial highways < Route 141 Route 147 >

Route 143 is a north/south highway on the south shore of the Saint Lawrence River. Until the mid 1970s when the province decided to renumber all highways, less autoroutes, it was known as Route/Highway 5. Its northern terminus is in Saint-François-du-Lac at the junction of Route 132, and the southern terminus is in Stanstead at the border with Vermont where the road continues as U.S. Route 5 in Derby Line.

Since Autoroute 55 closely parallels Route 143 for most of its length,much commercial traffic chooses the former. However it is a very busy route, taking much traffic from the border to the Sherbrooke local area. Route 143 closely follows the Saint-François River between Sherbrooke and Ulverton.

The road is often in notoriously poor condition, given its original cement was laid directly on a gravel road in the mid 1920s. In the years since it has been extensively resurfaced to the point the pavement is now more than three feet thick in places. Nonetheless it heaves extensively each spring thaw.
