Colorado Classic Bike Race – Thursday, Aug. 10

A high volume of traffic is anticipated on the roads this week due to the Colorado Classic Bike Race. Avoid using cell phones and/or other personal devices while driving, biking, or walking.

Motor vehicle driving tips:

  • Allow at least three feet between your vehicle and the bicycle.

  • Be patient and wait until it is safe to pass, as you would any other slow-moving vehicle. Be aware that when a road is too narrow for cars and bikes to ride safely side by side, bicyclists can legally ride in or near the center of the lane for more visibility and safety.

  • Please don’t honk your horn, you could startle the cyclist.

  • Watch for cyclists prior to turning to avoid cutting off a cyclist.

Drivers are Urged to Slow Down and Pay Attention

  • Speed reduction to 55 mph on I‐25 between South Nevada Avenue/Tejon Street and Cimarron/US24 (northbound and southbound)


  • Speed reduction to 45 mph on I‐25 from Cimarron/US24 to Bijou Street (northbound and southbound)

  • Speed reduction to 30 mph on US 24/Cimarron Street between 8th Street and I‐25 (westbound and eastbound)


  • Pay close attention when driving near the I‐25/Cimarron Project.

  • Slow down, observe speed limits, avoid distractions, and allow extra time for your commute.


  • Alternative route advised.

All Media Personnel: The I-25/Cimarron project is an active construction area. Access on the project site is restricted unless accompanied by a Colorado Department of Transportation or Kraemer representative.

PROJECT INFORMATION: The $113 million I-25/Cimarron Interchange Design-Build Project involves rebuilding the I-25 interchange between Colorado Avenue on the north and South Nevada Avenue to the south, 8th Street on the west and the Cimarron Street over Fountain Creek bridge on the east. Improvements are intended to provide enhanced operations, correct existing safety and design deficiencies, and to serve the anticipated short- and long-term travel demands in this area. When complete, this will be a high-functioning interchange that safely handles more vehicles and enhances multi-modal travel for those using I-25, US 24/Cimarron Street and the trail system along Monument and Fountain creeks. Substantial completion is planned for December 2017.
