DBM Contractors Inc. completed the installation of drilled shaft foundations, for the new southbound lanes of I-5 across the Willamette River in Eugene, Ore. Valued at approximately $1.95 million, the project required DBM to install 22 drilled shafts ranging from 60 to 96 in. in diameter and extending to depths up to almost 90 ft over more than 2,000 ft of bridge alignment along I-5.
The GC/CM for the project is Hamilton Construction. The entire project consists of replacing the existing “temporary” bridge built there in 2004, with a new arch deck design bridge. The bridge is one of Oregon’s longest and most heavily traveled. It spans the Willamette River connecting the Eugene and Springfield communities.
