ITD closed the Middleton Overpass in August 2020. Motorists were detoured for 8 months, while crews reconstructed the bridge.

The Middleton Road Overpass re-opened to the public ahead of schedule on Wednesday, April 28. Click here to see the Facebook Live Event.


In addition to making room for additional lanes on I-84, the new Middleton Road Overpass received new improvements.

This includes:

  • One lane in each direction on the overpass.
  • Wider shoulders on both sides to accommodate bicycles.
  • Sidewalk on the east side of the bridge.
  • 17’ vertical clearance on I-84.
  • A traffic signal at the intersection of Cherry Lane and Middleton Road.
