Quebec Route 143
highway in Quebec, Canada

Route 143 is a north/south highway on the south shore of the Saint Lawrence River, in the Centre-du-Québec and Estrie regions of Quebec. Until the mid-1970s when the province decided to renumber all highways other than 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 past the Derby Line–Stanstead Border Crossing as U.S. Route 5 through Derby Line to New Haven, Connecticut.
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 and takes 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, since its original cement was laid directly on a gravel road in the mid-1920s. It has been extensively resurfaced to the point the pavement is now more than three feet thick in places, but it heaves extensively at every spring thaw.
This brief starts where responsible research should: with the source description of “Quebec Route 143” as highway in Quebec, Canada. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as highway in Quebec, Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 29, 2026. The linked authority identifier is Q3443582. VIAF identifies the subject as 316991135. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
