Project Overview:

Construction is underway to widen and improve US 85 between Sedalia (SH 67) and Louviers in Douglas County.  The project will ease congestion, improve access to side streets and left-turn lanes, improve drainage, enhance safety, add wildlife fencing and build a new bridge.  The project is scheduled for completion in spring 2022.


Listed below are the traffic impacts and road work to expect this upcoming week of March 7 – 13 on the US 85 Widening project:

  • For US 85, north and southbound, there will be various shoulder closures from Sedalia to Titan Road for deer fencing and roadway grading. Work will take place Monday through Friday, 7 am – 5 pm.
