Crews changing southbound Colorado Boulevard entry to eastbound I-70

April 18, 2019 - Motorists will access eastbound I-70 differently from southbound Colorado Boulevard


DENVER—Starting Friday, April 19, travelers trying to access eastbound I-70 from southbound Colorado Boulevard will use a signalized left turn to enter the interstate. Crews will permanently close the right-hand loop.

Colorado Boulevard

This change in access provides a safer entryway to the interstate and is the first step in rebuilding the Colorado Boulevard/I-70 interchange as part of the Central 70 Project. Over the past few decades, new interchange designs have been implemented with less-curved exit ramps to reduce congestion and improve safety.

Signs will guide motorists well ahead of the new entrance ramp. The construction schedule is weather dependent and subject to change.

Safety Tips

Use the following tips to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones; obey the posted speed limits.

  • Stay alert! Expect the unexpected.

  • Watch for workers and drive with caution.

  • Don't change lanes unnecessarily.

  • Avoid using mobile devices such as phones while driving in work zones.

  • Turn on headlights so workers and other drivers can see you.

  • Be especially alert at night while driving in work zones.

  • Expect delays, especially during peak travel times.

  • Allow ample space between you and the car in front of you.

  • Anticipate lane shifts, and merge when directed to do so.

  • Be patient!
