Design for Launching Great Bear River Bridge near the Arctic Circle

The Great Bear River Bridge (GBRB) was designed as a 5-span (80m-100m-100m-100m-80m) steel plate girder bridge. It is an important river crossing located on the annually constructed winter road along the Mackenzie Valley, near the community of Tulita, Northwest Territories of Canada, just south of the Arctic Circle. The site is located 800 meters upstream from the confluence of the Great Bear River and the Mackenzie River. The high ice level from both upstream and downstream, the unstable hydrology conditions, and the Northern harsh climate put great challenges to the bridge designers. This paper presents the methodologies employed to overcome these challenges, including the incremental launching for the steel plate girder erection.
