Matanuska-Susitna Borough

Bodenburg Creek Bridges

Scope

The primary purpose of this project is to repair or replace existing bridges across Bodenburg Creek in Butte, Alaska. The three existing bridge locations are at Back Acres Ave, Elk Rd and Northbridge Rd. This project will ensure these three bridges are meeting current standards for scour protection and loading. The secondary purpose is to provide access between two dead-end roads to improve emergency access and egress, and to minimize maintenance costs.

Project Benefits

The project will improve aging infrastructure, protect the bridge abutments from deterioration and improve area circulation. The proposed access easements will be used to develop road connections to Borough local road standards, consistent with existing roads in the neighborhood. Acquisition of access easements between the roads is necessary to allow for some bridge closures during repair. Connecting Elk Road and Northbridge Road on the east side of Bodenburg Creek also provides an alternative route for residents to evacuate and for emergency personnel to gain access in the event of an emergency affecting bridge access, such as fire, flooding or bridge failure. Maintenance costs will also be minimized, through snow removal efficiencies.

Project Status

The reconnaissance investigation phase was completed in the summer of 2015, including bridge inspection, topographic surveys, and hydraulic and geotechnical engineering studies. Right-of-way survey and acquisition are now complete, and construction improvements are beginning in April 2017. Dirtworks, Inc. is the construction contractor.
