Repairs complete on northbound Glenn Highway bridge
It’s smooth sailing again over the Eagle River bridge.
The Alaska Department of Transportation & Public Facilities said Tuesday it has completed repairs to the earthquake-damaged northbound crossing. The damage suffered in the magnitude 7.1 quake on Nov. 30, 2018 was to abutments on each end of the bridge, which caused commuters to hit irritating bumps coming onto and leaving the bridge.
In a Tuesday Facebook post, the department said it used polymers injected beneath the roadway to help raise the approach structure of the bridge.
“The work included stabilizing the bridge approaches and leveling the bumps on the highway. The construction team used a first-time in Alaska process of injecting a polymer below the roadway surface to raise the approach structure at the abutment and stabilized the material below the roadway,” the department wrote.
The work began Sept. 3 and was completed by Kiewit Construction. Although some lanes were closed during the work, the bridge was never completely closed during the repairs.
Although the bridge repairs are complete, work on the department’s larger Glenn Highway Capacity Improvement Phase II in the area continues. That project will eventually add a three-lane southbound crossing to mirror the northbound bridge completed in 2015. When the project is completed in 2020, the southbound bridge will replace the existing two-lane crossing, which will become a frontage road.
