Overview
Construct a new Hwy 101 bridge over the floodplain in Chanhassen. The raised roadway will minimize transportation disruptions caused by seasonal flooding of the Minnesota River Valley.
Location
- Hwy 101 between existing Minnesota River bridge in Shakopee and Hwy 61/Flying Cloud Drive in Chanhassen
Schedule
- Letting: May 2014
- Proposed construction: 2014-2015
Estimated cost*
- $34 million (MnDOT)
- $17-20 million (Carver County
- Total: $51-54 million
*Cost estimate based on a four lane bridge structure over the Minnesota River floodplain (MnDOT portion). The carver county portion is based on a roundabout centered in the existing “wye” at the north end of the project and includes additional improvements on Flying Cloud Drive and Hwy 101 to the north. Construction costs only reported.
Funding sources
MnDOT flood Mitigation Program ($20M, LRIP, CTB, Scott and Carver Counties)
Project status
Hwy 101 between Chanhassen and Shakopee
Preliminary road, bridge, and geotechnical engineering have begun. Carver County is leading the project delivery and design effort for the Hwy 101/Flying Cloud Drive “wye” at the north end of the project, and the overall project delivery and roadway design (including MnDOTs portion). MnDOT will continue to assist Carver County with bridge design, construction engineering and other engineering services as needed. Cost estimates are still being refined during preliminary design and soils investigation.
Benefits
- Construct new bridge across the floodplain north of the Minnesota River channel to raise the roadway out of the 100-year flood elevation
- Reduce the frequency and duration of road closures caused by seasonal flooding of the Minnesota River Valley
- Minimize regional and local transportation disruptions that occur when other area river crossings must be closed due to seasonal flooding
- Minimize long-term maintenance and repair costs
- Add a multiuse trail that will connect regional trails, a roundabout at the "wye" and additional improvements along County Road 61
