CSAH 10 River Crossing in Watertown

Carver County, Minnesota

The 70-year-old CSAH 10 Bridge over the Crow River was deteriorating and in need of rehabilitation or replacement. The narrow bridge provided the only crossing for miles, was susceptible to flooding, and deemed scour critical.

The initial community goal of a new bridge location shifted toward preserving the historic bridge. After determining that rehabilitation was not an option, construction plans for a replacement bridge called for a complete crossing closure. A staged construction plan was developed to ease local resident and business concerns. Traffic moved across one half of the bridge as the other half was dismantled and replaced then rerouted to the new bridge as the other section was completed. After evaluation of the intersection adjoining the bridge, a high-density, single-lane roundabout was selected as a solution to downtown traffic congestion.

A solution was achieved that would replace an aging structure and handle high traffic. The solution was workable for all parties, kept the downtown business community vibrant, and maintained the link that keeps the community connected.
