Trans-Labrador Highway

The Trans-Labrador Highway (TLH) is a Canadian highway located in the province of Newfoundland and Labrador. It is the primary public road in Labrador and one of the few in that part of the province.

The original western/central portion of the TLH is designated as Route 500 and measures 549 km (341 mi) divided as follows:

• Quebec - Labrador boundary to Labrador City/Wabush (23 km, asphalt surface)
• Labrador City/Wabush to Churchill Falls (238 km, asphalt and gravel surface)
• Churchill Falls to Happy Valley-Goose Bay (288 km, asphalt and gravel surface)

Heading Southeast is Route 510, the north portion of the TLH that has been designated Labrador Coastal Drive:

• Lake Melville/Hamilton Inlet/Happy Valley-Goose Bay, to connect Cartwright Junction (87 km south of Cartwright) (250 km, gravel surface).

The remaining portion of Labrador Coastal Drive runs 409 km, divided as follows (Route 530):

• Cartwright to Port Hope Simpson (179 km, gravel and asphalt surface, of which 87 km is paved).
• Port Hope Simpson to Mary's Harbour (58 km, gravel surface).
• Mary's Harbour to Lodge Bay (12 km, gravel surface).
• Lodge Bay to Red Bay (74 km, gravel surface).
• Red Bay to Quebec - Labrador boundary via Blanc Sablon (86 km, asphalt surface).

The TLH runs through dense wilderness for most of its length with no roadside services between communities. Travelers attempting to drive the TLH in winter months should plan for unpredictable and extreme weather and road conditions.

The TLH/Labrador Coastal Drive connects with Quebec Route 389, which runs 570 km through wilderness north from Baie-Comeau to the Quebec - Labrador boundary.
