Dakota County, in cooperation with the cities of Inver Grove Heights and Eagan, is proposing to expand County Road 26 (Lone Oak Road/70th Street West) 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 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 is being proposed at the intersection of County Road 26 and County Road 63 as well as additional turn lanes, drainage improvements, curb and gutter, multi-use trails, and an underpass serving the Mendota-Lebanon Greenway system.
The project will accommodate increasing traffic volumes and improve safety in a developing area of Dakota County.

Environmental Assessment Worksheet
Dakota County has prepared an Environmental Assessment Worksheet (EAW) for the County Road 26 and County Road 63 Improvement Project. The document can be accessed electronically on the project website at
A virtual open house will be posted from May 14-21 to the project website which will share information about the EAW, project and construction. Written comments on the EAW will be accepted until June 3, 2020. They can be submitted via the project website or directed to:

A public meeting about noise barriers was Feb. 25, 2020.
Dakota County considered several noise barriers along County Road 26 and County Road 63 in Inver Grove Heights as part of the project. The proposed noise barriers are under consideration as part of the federal aid project requirements for noise mitigation.
Properties are being offered the chance to vote on the proposed noise barrier. Only residents and owners of benefitted receivers can vote. Benefitted receivers are those properties that would receive a noise benefit (defined as a reduction of at least five decibels) from the construction of the noise barrier.
If 50 percent or more of all possible voting points from eligible voters are received after the first request for votes, the majority of votes (based upon the votes received) determines the outcome. If less than 50 percent of the possible voting points for a wall are received after the first request, a second ballot will be mailed to the eligible voters who did not respond.
