Dakota County, in cooperation with the cities of Inver Grove Heights and Eagan, will expand County Road 26 (Lone Oak Road/70th Street W.) from a two-lane roadway to a four-lane divided roadway from Highway 55 (Courthouse Boulevard) in Eagan to Highway 3 (South Robert Trail) in Inver Grove Heights.
The project will also reconstruct County Road 63 (Argenta Trail) as a two-lane divided roadway on a new alignment from Amana Trail to the newly constructed 65th Street in Inver Grove Heights. A roundabout will also be built at the intersection of Lone Oak Road/70th Street W. and Argenta Trail as well as additional turn lanes, drainage improvements, curb and gutter, multi-use trails, and an underpass serving the Mendota-Lebanon Greenway system.
