DBM Completes Foundation Shafts for Alaska’s Glenn Highway Job Location: Caribou Creek/Glenn Canyon Highway, Palmer, AK Project Owner: Alaska Department of Transportation Project Description: DBM Contractors recently completed construction of a 39,000 square-foot permanent anchored pile wall, along with the drilled shaft foundations for a new replacement bridge over Caribou Creek on Alaska’s Glenn Highway. This $5.6 million portion of the $35 million construction project will enable the replacement of a 1950s-era bridge and the widening of nine miles of highway. The bridge foundation work consisted of drilling three, 10-foot diameter shafts with permanent, full-depth steel casing, and socketing the shafts into bedrock to depths of 80 to 115 feet. DBM also designed and built a permanent anchored pile wall to retain the fill required to widen the existing roadway. The entire construction project is scheduled for completion in the summer of 2005. Other contractors involved in construction include Quality Asphalt Paving, the general contractor for the project, and Sandstrom & Sons, Inc., which will build the bridge structure and permanent concrete facing for the retaining wall. Both companies are based in Anchorage, Alaska. |
