US 85 Widening Project in Douglas County from Sedalia to Louviers

Work this Week
June 20 - 24, 2022

Listed below are the traffic impacts and road work to expect this upcoming week of June 6-20 for the US 85 Widening project:

  • Various Inside/outside lane closures for northbound US 85 for grading and fencing work activities.
  • Intermittent traffic stops just south of Airport Road near mile marker 193 for equipment crossings. There will be flaggers to direct traffic.
  • Weather permitting, work will take place Monday through Friday, 7am-5pm.

Weather permitting, our project is scheduled to complete by end of June. We will continue to keep you updated on any schedule changes and appreciate your continued patience.

About the Project

Starting Apr. 6 through Apr. 8, crews have several activities planned that will impact traffic and improve safety for travelers. On Apr. 6-8, between 9 a.m. to 1 p.m., crews will work on the slope east of US 85 between mile posts 193 and 191.75. Motorists can expect delays up to 20 minutes while crews work remove loose rock from the hill and roadway. The work is being implemented to keep falling debris away from the roadway and traffic. For the safety of motorists and workers, drivers are reminded to obey all posted speed limits through the project. Reduced lane widths and reduced speed limit of 45
mph will be in effect until further notice. CDOT recommends that motorists utilize I-25 as an alternate route during these closures to avoid delays while commuting.

  • The speed limit is reduced to 45 mph, and work zone fines are doubled.
  • Motorists should plan for possible long traffic delays during the days of Apr. 6-8 from 9 a.m. to 1 p.m. and are advised to avoid the area by using I-25 as an alternate route.
