Best Highway Bridge & Project of the Year Nominee: Glenn Highway Phase 1 & 2
When reconstructing a three-mile segment of Glenn Highway in Eagle Creek, Alaska, engineers had to consider two types of travelers: human drivers and spawning fish.
To that end, the team built two four-span bridges over the Eagle River and an earth retaining wall while replacing the 50-year-old culverts to ease fish passage. The project required 436,000 cu yd of earthwork, 50,000 tons of asphalt paving and 250,000 tons of additional material.
