About this project
Summary of work
This project involves raising Hwy 169 and Hwy 22 one foot above the 100-year flood elevation to maintain traffic during high water events. When these highways were originally constructed in the early 1960’s, the Minnesota River high-water elevation was assumed at 751 and the roads were constructed accordingly. The actual 100-year flood elevation in this area ranges from about 756.0 to 756.6. View project overview map (PDF).
- Unsuitable soils in reconstruction areas
- Impacts to 6(f) environmental properties of Seven Mile Creek and Riverside Park
- Coordination with rehabilitation of Hwy 99 bridge over Minnesota River at Saint Peter
- Management of traffic during construction and access to businesses during construction
