Featured Presentation: Using ABC to Address Climate Change in Alaska’s Arctic (35 Minutes)

Description: The village of Kivalina, Alaska, is 80 miles north of the Arctic Circle on the Chukchi Sea and is home to around 450 people. Due to rising sea levels and a deterioration of sea ice, the village is at risk of being inundated and has had its coastline eroding at a rapid rate over the last 20 years. A gravel road, causeway, and the Kivalina Lagoon Bridge were constructed to allow the village to begin relocating to higher ground eight miles away and to provide an evacuation route during severe storms. Due to the remote location, short construction season and lack of nearby infrastructure, this project utilized the CM/GC (construction manager/general contractor) project delivery method to accelerate construction and reduce risk. Constructed in 2020, the bridge included details, such as full-depth precast deck panels, that minimized specialized equipment or labor. An overview of the challenges, design and construction details, and lessons learned will be presented.
