Reconstruction of Middleton Road Bridge over Interstate 84 complete, open to traffic

The Middleton overpass is nearly complete

The Idaho Transportation Department has completed the reconstruction of the Middleton Road Bridge over Interstate 84 ahead of schedule and will open it to the public tonight. ITD will cover the opening at 8 p.m. live on Facebook.

The reconstruction was necessary to make room for additional travel lanes for I-84. ITD has begun the first phase of constructing a third travel lane in each direction. The new Middleton Road Bridge is long enough that a future fourth lane can be constructed without conflict.

The bridge was rebuilt ahead of schedule by contractor Concrete Placing Company. The cost of construction was $5.5 million.

The new bridge features a travel lane in each direction, wider shoulders, and a sidewalk on the north side. The design allows for future expansion of Middleton Road without the need to rebuild the entire structure. The project also constructed a signal at the intersection of Middleton Road and Cherry Lane, north of I-84.

“This project went really well and this new bridge is a great investment for transportation in the area,” said ITD Project Manager Michael Lucas. “We had a lot of coordination with some local road projects and the work on the Interstate. The crews worked through Covid-19 complications, adverse weather, and a lot of night work to get the job done. I appreciate the public’s patience during construction.”

The Department will quickly move to the second bridge over I-84 restricting the widening, Ustick Road. That bridge lies a little over a mile to the west of the Middleton Road Bridge. The Ustick Road bridge reconstruction project requires two separate bridge structures to be rebuilt, one over I-84 and the other crossing the Notus Canal. ITD will release a timeline for that project at a later date. Current information on the Ustick Road Overpass project can be found online at
