Alaskan bridge uses innovation in harsh climate

The Federal Highway Administration (FHWA), in cooperation with the Gwichyaa Zhee Gwich’in tribal nation, is building Alaska’s first geosynthetic reinforced soil–integrated bridge system (GRS–IBS) project.

The project to replace a bridge over the Sucker River in Fort Yukon, 11 miles north of the Arctic Circle, will test GRS–IBS technology in a harsh environment with record temperatures of 100°F and minus 78°F. The project will improve access for area residents.
