加拿大的育空地区授予了16000万加元的尼苏特林湾桥梁替代项目 -the largest-ever capital project forthe territory—to Calgary-based Graham Infrastructure LP.

“The Nisutlin Bay Bridge is an important landmark for Teslin, a key gateway to the Yukon and a critical transportation link along the Alaska Highway that keeps our communities connected,” said Canada's Minister of Highways and Public Works, Nils Clarke, in a statement. “This project is an excellent example of the benefits provided by the Yukon First Nations Procurement Policy and will create jobs for Teslin Tlingit community members and Yukoners.”

The existingAlaska Highwaybridge crosses Teslin Lake, Yukon, at the narrowest point of the bay. At 1,917 ft in length, it is the longest bridge on the Alaska Highway and serves as a critical transportation link for the territory. Originally built in 1953 by Canada’s Dept. of National Defense, the span is nearing the end of its service life.

新的桥梁将与现有桥一起建造，并计划在2026年完成。原始跨度将在新的桥梁进行服务时退役。

This area is home to a First Nations group, the Inland Tlingit. The Government of Yukon developed the design working in collaboration with the Teslin Tlingit Council. The two signed a project charter for the bridge in 2019.

“Replacing the iconic Nisutlin Bay Bridge is a major project for our community, the largest in recent memory,” said Naa Shaáde Háni of Teslin Tlingit Council Eric Morris in a statement. “We look forward to continuing to work with the Yukon government and Graham Infrastructure LP to maximize the economic benefits for the community while minimizing the social impacts of the project.”

新的bridge will improve safety for drivers, while allowing for increased traffic volume that will accommodate larger loads of commercial and strategic goods to supply the Yukon and Alaska.

The bridge also will include a pedestrian walkway and be lined by 30-ft-tall street lamps. And the span is designed for the seismic resistance required for the earthquake zone.
