CDOT will shift traffic onto the new westbound I-70 bridge over 32nd Avenue during overnight hours Feb. 21

Travel Advisory

February 21, 2023 - Central/Eastern Colorado - This shift onto the new westbound I-70 bridge over 32nd Avenue signifies the completion of a major milestone for this project

Jefferson County — As part of the Colorado Department of Transportation's I-70 over 32nd Avenue Bridge Replacement Project, motorists can expect a traffic shift during overnight hours on Tuesday, Feb. 21 onto the newly completed westbound bridge structure.

Westbound I-70 traffic has been under a temporary shift east since last September while crews removed and replaced the westbound bridge. This shift onto the new westbound I-70 bridge over 32nd Avenue, which moves westbound traffic back onto mainline I-70, signifies the completion of a major milestone for this infrastructure improvement project.

Traffic Impacts

Work for the Feb. 21 traffic shift will include removing existing barriers, restriping the lanes, and realigning traffic directly onto lanes of the new westbound bridge.

  • The lanes will be temporarily reduced in width to 11-feet with 2-foot shoulders
  • Motorists can expect to encounter double lane closures and short delays on westbound I-70 during the overnight shift between 9 p.m. and 6 a.m.
  • Once the overnight shift is implemented, three lanes of traffic will be maintained in each direction of I-70 through the work zone
  • Motorists are urged to heed the posted speed limits and drive cautiously through the work zone
  • The schedule could change depending on weather conditions. COtrip.org will have the latest information

Upcoming Work

Removal of the existing eastbound I-70 bridge over 32nd Avenue is expected to begin by mid-March. This will entail shifting eastbound traffic outward, and removing and replacing the eastbound bridge in stages to minimize traffic impacts.

The project consists of replacing both I-70 bridges over 32nd Avenue which have exceeded their lifespan for optimal safety and longevity. Work began in February 2022 and is expected to be complete by December.
