Denver Metro Area Wrong-Way Signage Improvements Phase I

About the Project

The Colorado Department of Transportation and contract partner CC Enterprises are pleased to announce the completion of Phase 1 of the wrong-way driving counter measures sign project located in multiple counties in the Denver Metro Area on November 10. The project took 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 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 included the removal and replacement of approximately 900 aging signs. The new signs are larger in size, which will improve visibility and safety.  Additional wrong-way signs were 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 was to lessen the chance of a motorist entering the interstate from the wrong direction. The new signage and pavement markings enhance safety by alerting motorists of wrong-way driving maneuvers onto these non-signalized highways.

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