About the Project:

This project includes upgrading infrastructure at I-70 over 32nd Avenue by replacing the bridges and making safety improvements to support increased traffic on the I-70 corridor.

Work includes removal and replacement of both the eastbound and westbound bridges. Built in 1968 when this portion of I-70 was being constructed, the bridges have undergone frequent maintenance and repair work but have now exceeded their 50-year lifespan, resulting in this replacement project.

The new bridges will have a 75-year lifespan which will lead to fewer maintenance visits and associated lane closures to conduct repairs. The new structures will also have wider shoulders for increased safety. Construction of the new shoulders will be accomplished by filling in the current gap between the westbound and eastbound bridges.

Finally, the bridge guardrail will be upgraded to meet current safety standards.

Work Schedule

  • This five-phase project began on February 14, 2022 and is expected to last until late fall 2023.
  • Phase I lasts until early spring 2022 and includes minor bridge demolition, asphalt removals and utility relocations.
  • Phase II to Phase IV include constructing the median portion of the new westbound I-70 bridge and installing detour pavement, removing and replacing both westbound and eastbound I-70 bridges, constructing permanent roadways, and finalizing bridge overlays.
  • Final asphalt overlay, striping and landscaping will be completed in Phase V.
  • Work will be performed during daytime hours Monday to Friday with some night and weekend work expected.

Traffic Impacts

  • Traffic shifts, narrowed lanes and reduced speeds are in place at the approaches to and at Exit 264 (Clear Creek Pkwy/Youngfield/32nd Avenue) along both directions of I-70 from Exit 263 (Colorado Mills Pkwy) to Exit 266 (Ward Road/CO 72).
  • Three lanes of traffic will be maintained during daytime hours, but the lanes are narrower due to the traffic shifts.
  • Overnight (non peak-travel hours) single or double lane closures in both directions of I-70 from Exit 263 to Exit 266 will exist until completion.
  • Both westbound and eastbound 32nd Avenue are under a single lane reduction configuration with occasional full closures until completion.
