CSAH 133 Expansion and Roundabout

Stearns County reconstructed CSAH 133 between CSAH 75 and 15th Avenue in St. Joseph, along with the construction of dual left turn lanes along eastbound CSAH 75. The final roadway section included a four-lane section along CSAH 133 with a four-foot-wide median and a 2x1 roundabout at the CSAH 133 and Elm Street.

Some of highlights of the project include traffic modeling and analysis at the Elm Street and CSAH 133 intersection, producing a preliminary design that balances the roadway expansion with right-of-way impacts to surrounding businesses, and reviewing potential locations for stormwater treatment to meet both County and City MS4 and Sauk River Watershed District treatment requirements.
