Building an ice bridge
Tech. Sgt. Tim Broderick pumps water from the Tanana River to build up the ice thickness Nov. 24, 2008, at Fairbanks, Alaska. The ice bridge takes six to 10 weeks to complete in sub-zero weather. It is five-feet deep, 32 miles long and capable of supporting more than 110 tons -- and will melt back into the river when spring thaw hits. The ice bridge enables 354th CES Airmen to access and perform annual maintenance at Blair Lakes Bombing Range. Sergeant Broderick is assigned to the 354th Civil Engineer Squadron range maintenance.
