I-225 Bridge Rehabilitation at 6th & 2nd Avenues

About the Project

The I-225 Bridge Rehabilitation at 6th and 2nd avenues will improve the driving surface of the northbound and southbound I-225 bridges over 2nd and 6th avenues. These bridges have an elevated slope in the middle, and this project will help flatten the driving surface by putting down asphalt between the middle of the bridge and the approaches to each bridge.

Along with leveling out the lanes, this project includes:

  • Replacing the bridge expansion joints with plug joints
  • Replacing several concrete panels in both directions of I-225 just north of 6th Avenue
  • Installing a waterproof overlay
  • Strategic mill and overlay
    • The overlay involves putting down gradually decreasing depths of asphalt from the middle of the bridge to the bridge approaches to even out the roadway surface

Project Benefits

Improve and flatten the driving surface of the northbound and southbound I-225 bridges over 2nd and 6th avenues.

Work Schedule

  • The project began work Sunday, Aug. 10, 2025
  • Project is expected to take about three months to complete
  • Work will mainly occur overnight, with working hours from 7 p.m. to 5 a.m., Sunday
    through Thursday

Traffic Impacts

Motorists can expect the following impacts during the period of construction:

  • Single and double-lane closures
    • Both directions of I-225 from just north of 6th Avenue (MP 9.5) to just south of Alameda Avenue (MP 7.5)
  • Work will be done in only one direction at a time on I-225
    • Single lane closures beginning at 7 p.m. each night
    • Double lane closures at 10 p.m.
    • All lanes will reopen by 5 a.m. the following day
  • I-225 full closure:
    • There was a successful full closure of northbound I-225 at 6th Avenue for one night on Oct. 26. This closure allowed crews to put down asphalt on the bridge surface to help even out the pavement.
    • No additional full closures on I-225 are anticipated for this project.
  • Motorists are urged to drive with extra caution through the work zone, heed the signs, watch for crew members and equipment, do not speed and give plenty of following distance
  • Construction schedules can change depending on weather and other factors
