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

About the Project

The I-225 Bridge Rehabilitation at 6th and 2nd avenues improved the driving surface of the northbound and southbound I-225 bridges over 2nd and 6th avenues. These bridges had an elevated slope in the middle, and this project helped 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 included:

  • 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
