2020 Construction

Construction activities on and around the Systems Interchange continue to increase into spring construction in 2020. Construction on the Interchange occurs year-round, but spring weather conditions allows more work than during winter conditions. This means additional construction crews and equipment will be in the work zone. Please slow down and stay alert.

Construction activities in the spring and summer of 2020 are illustrated on the 2020 Construction Activities interactive map below. Travelers in the area will continue to see construction activities such as I-380 median bridge construction, I-80 bridge widening over U.S. 6, and work on the ramp bridges over Clear Creek in the northeast and southeast quadrants of the interchange. Additional construction activities in 2020 include:

  • Realignment of 340th Street SW.
  • Continued grading along I-380 and I-80.
  • Construction of the I-80 eastbound to I-380 northbound flyover ramp.
  • Construction of the I-80 eastbound to U.S. 218 southbound ramp.
