January 2022 Project Update

The Cliff Road at I-35W South Ramp Improvement Project is a city led project that reconstructs the existing thru-stop (T) intersection at the intersection of I-35W Southbound Ramp and Cliff Road W (CSAH 32) to a roundabout approximately 200’ south. The project extends Cliff Road W (CSAH 32) to provide improved access and mobility to the adjacent industrial area generating high volumes of freight and commuter traffic immediately adjacent to the I-35W corridor. The immediate need for this project is to remedy the existing inadequate sight lines and speed reduction distance for high speed traffic exiting the freeway, primarily heavy commercial trucks accessing the industrial area.
This city-led project is being completed in partnership with Dakota County and MnDOT. The total estimated project cost of the Cliff Road at I-35W South Ramp Improvement Project is $6.5 million dollars. The City has secured $3 million in funding from federal and state grants. The remainder will be funded by City of Burnsville and Dakota County.
