The primary purpose of this project was 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 is to ensure these three bridges are meeting current standards for scour protection and loading. The secondary purpose was to provide access between two dead-end roads to improve emergency access and egress, and to minimize maintenance costs.
The project improves aging infrastructure, protect the bridge abutments from deterioration and improves area circulation. The access easements develop road connections to Borough local road standards, consistent with existing roads in the neighborhood. Acquisition of access easements between the roads was 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 be minimized, through snow removal efficiencies.
The construction was substantially complete in September 2017 by the construction contractor, Dirtworks, Inc. with Swalling Construction as the sub for the Northbridge Road bridge construction. Total completion is expected in the Spring 2018 with the application of topsoil and seeding.
