Construction begins on new NWT all-season highway

The Tłı̨chǫ All-Season Road is a new 97km gravel road that is expected to take up to three years to complete.


The official groundbreaking ceremony was held August 24th in Whatì, Northwest Territories for the Tłı̨chǫ All-Season Road (TASR) – a new 97km gravel all-season road to Whatì from Highway 3 west of Behchokǫ̀.

Replacing the winter road to Whatì with an all-season road will make the highway system more resilient to the impacts of climate change.

Construction is expected to take up to three years.

The P3 project, with a total contract value of $411.8 million over 28 years, was awarded in November 2018 to North Star Infrastructure, a consortium made up of Kiewit Canada Development Corp., and the Tłı̨chǫ Government, with Peter Kiewit Sons ULC, Hatch Corp. and Thurber Engineering Ltd.

The road is expected to officially open to traffic in 2022.

“Less than three years after the official opening of the Inuvik Tuktoyaktuk Highway, the Government of the Northwest Territories, with our partners, is preparing to start yet another transformative highway project: the Tłı̨chǫ All-Season Road. This 97-kilometre road will bring many positive benefits to residents of the Tłı̨chǫ region and residents across the NWT for generations to come. Our government will continue to work closely with our public and private sector partners to advance strategic infrastructure projects across the Northwest Territories,” said Wally Schumann, Minister of Infrastructure and Industry, Tourism and Investment, in a media release.
