Highway 101 Causeway aerial photo


In 2016, Hennepin County carried out road construction on Highway 101/Bushaway Road to add turn lanes and a bicycle/walking path. Highway 101 crosses Lake Minnetonka between Gray’s Bay and Wayzata Bay, so the Minnehaha Creek Watershed District (MCWD) recognized the opportunity to capitalize on the county’s construction work by protecting and improving shoreline along the road. MCWD worked with Hennepin County to reconstruct the shoreline and add native vegetation, which reduces erosion, absorbs stormwater, provides wildlife habitat, beautifies the roadway, and reduces the risk of lake waves freezing on the road during winter months.

As part of this project, MCWD also partnered with the City of Minnetrista to carry out a separate wetland restoration, fulfilling a floodplain permit requirement related to the Highway 101 causeway project. This restoration, on a city-owned parcel along Jennings Bay near Painter Creek, increases water storage in case of flooding, and will help the city meet permitting requirements for future projects.
