About the Project

The Colorado Department of Transportation and contract partner CC Enterprises will begin a wrong-way driving counter measures sign project located in multiple counties in the Denver Metro Area on November 10. Phase 1 of the project will take place at 83 off-ramps at the following locations:

  • I-70 Mountain Corridor from the Eisenhower-Johnson Memorial Tunnel to Morrison (I-70 from Mile Point 216 to MP 260)
  • I-70 Metro Corridor from Morrison to E-470 (I-70 from MP 260 to MP 290)
  • I-70 Eastern Corridor I-70 from E-470 to Strasburg (I-70 from MP 290 to MP 328)
  • I-225 from I-25 to I-70 (I-225 from MP 2 to MP 10)
  • US 6 from I-70 in Golden to I-25 (US 6 from MP 276 to MP 283.5
  • US 285 from Pine Junction to I-25 (US 285 from MP 231 to MP 260)

Work in Phase 1 of this project will include the removal and replacement of approximately 900 aging signs. The new signs will be larger in size, which will improve visibility and safety. Additional wrong-way signs will be added at most locations, totaling about 1500 wrong-way/roadway signs and posts installed in this phase of the project. The goal of the project is to lessen the chance of a motorist entering the interstate from the wrong direction. The new signage and pavement markings will enhance safety by alerting motorists of wrong-way driving maneuvers onto these non-signalized highways.

Additional work will consist of installing overhead signage on existing signal structures and modifying signal bulbs to indicate lanes with through motions at the intersections.
