Construction work will begin Wednesday on the bridge over Grant Creek on Prospect Drive. The work is expected to continue through November 21st.

According to Doug Harby with the City of Missoula engineering division, the work is necessary because high spring runoff in 2011 compromised the eastern abutment of the bridge by washing away riprap or protective rock fill.

Harby says the bridge itself is secure, but the approaching roadway needs to be repaired. The cost of the repairs is estimated at just over $67,000, and will be carried out by Western Excavating.

Harby says traffic will be rerouted from the Old Quarry Road through the Rocky Mountain Elk Foundation parking lot to Stone Ridge during the project.
