Trans-Labrador Highway

The Trans-Labrador Highway (TLH) is the primary public road in Labrador, the mainland portion of the province of Newfoundland and Labrador, Canada. The highway's total length is 1,149 km (714 mi). The paving of the entire highway was completed in July 2022.

The original western/central portion of the TLH is designated as Route 500 and measures 543 km (337 mi) divided as follows:

Quebec - Labrador boundary to Labrador City/Wabush (18 km (11 mi), asphalt surface)

Labrador City/Wabush to Churchill Falls (244 km (152 mi), asphalt surface)

Churchill Falls to Happy Valley-Goose Bay (281 km (175 mi), asphalt surface)

Heading southeast is Route 510, the north portion of the TLH that has been designated Labrador Coastal Drive and measures 606 km (377 mi) divided as follows:

Happy Valley-Goose Bay to Cartwright Junction (287 km (178 mi), asphalt surface)

Cartwright Junction to Port Hope Simpson (103 km (64 mi), asphalt surface)

Port Hope Simpson to Mary's Harbour (51 km (32 mi), asphalt surface)

Mary's Harbour to Lodge Bay (12 km (7.5 mi), asphalt surface)

Lodge Bay to Red Bay (78 km (48 mi), asphalt surface)

Red Bay to Quebec - Labrador boundary via Blanc-Sablon (77 km (48 mi), asphalt surface)

The TLH runs through dense wilderness for most of its length with no roadside services between communities.

Route 500 connects with Quebec Route 389, which runs 567 km (352 mi) through wilderness north from Baie-Comeau to the Quebec - Labrador boundary. Cell phone reception along the Trans-Labrador Highway is limited.

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.
