I-70 over 32nd Avenue Bridge Replacement

Work this Month
February 1 - 28, 2023
  • This month, traffic will be shifted back onto the new westbound I-70 bridge over 32nd Avenue while crews begin removing and replacing the existing eastbound bridge at this location.
  • Motorists can expect various overnight lane closures on I-70 during the shift and events like removal of the eastbound bridge.
  • Various lane closures including full closures over two weekends of 32nd Avenue will be in place during the removal of the bridge and safety critical work.

About the Project

This project is designed to improve public safety and add capacity to support increased traffic on the I-70 corridor.

Work includes removal and replacement of both eastbound and westbound bridges E-16-HEA and E-16-HFA with concrete box girders and precast deck panels. Work will also include final surface construction for the bridges, roadway overlay and landscaping.

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.
