Newfoundland and Labrador Route 510

The Trans-Labrador Highway (TLH) is a highway located in the province of Newfoundland and Labrador, Canada. It is the primary public road in Labrador. Its total length is 774.66 mi (1,246.69 km). Due to the harsh winters and sparse population in most of Labrador, long parts of the road are a well-packed asphalt/gravel surface that is re-graded annually (usually in mid to late May). There are plans to complete the paving of the highway within the next years.

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

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:

The TLH runs through dense wilderness for most of its length with no roadside services between communities. The TLH/Labrador Coastal Drive connects with Quebec Route 389, which runs 567 km (352 mi) through wilderness north from Baie-Comeau to the Quebec - Labrador boundary.

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".

The Phase I section of the TLH began undergoing paving operations in 2009; by October 2011, a stretch of approximately 140 km (87 mi) leading east from Labrador West had been paved, as well approximately 100 km (62 mi) heading west from Goose Bay towards Churchill Falls. The entire Phase I section of the TLH was completed in 2014.

In 1997 the Government of Newfoundland and Labrador committed to building an extension of the TLH, connecting Happy Valley-Goose Bay with an existing isolated road network serving coastal communities on the Strait of Belle Isle. The impetus for this project was the federal government's desire to cut costs and remove itself from subsidizing coastal ferry service to Labrador outports which was being provided by the federal Crown corporation Marine Atlantic.
