In the 2020 budget, the provincial government allocated $200,000 for a pre-feasibility study for a road to connect the north coast of Labrador to the Trans-Labrador Highway.
Construction and development
Phase I, upgrading Labrador West to Happy Valley-Goose Bay
The original TLH from Labrador West (Labrador City/Wabush) to Happy Valley-Goose Bay was completed in 1992. Some sections were poorly built or in need of upgrades due to increased traffic use, particularly the section between Churchill Falls and Happy Valley-Goose Bay. In the summer of 1999, $60 million was allocated to upgrade the highway as part of the "Labrador Transportation Initiative".

Why this record matters
“Trans-Labrador Highway” is worth following because a concise public description often conceals a longer documentary argument. Here, Trans-Labrador, Highway and highway provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 22, 2026. The linked authority identifier is Q3443909. The first chronological checks are 2022, 2020, 1992 and 1999.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
