ITD is replacing the Ustick Road Overpass and Notus Canal bridge.
Replacing the overpass will allow additional lanes to be built on I-84. Construction on the overpass began in May 2021 and expected to be completed by Summer 2023. The overpass is part of ITD's improvements to I-84 in Caldwell.

The Idaho Transportation Department removed the Notus Canal Bridge and started building the new bridge.
As a reminder, the Ustick Road Overpass remains closed to through traffic.

The Idaho Transportation Department began work on the Notus Canal Bridge on Ustick Road in mid-September. A new detour route is in place to access local businesses.
What to expect:
All work is expected to be complete in Summer of 2023.
In addition to making room for additional lanes on I-84, the new Ustick Road Overpass will include:
* ITD will build the Ustick Overpass wide enough to accommodate five lanes, but will not open the bridge up to five lanes until the City of Caldwell widens Ustick Road on either side of the bridge. Click here for detailed plans.
ITD conducted a detailed traffic analysis of I-84 in 2018. ITD analyzed whether or not a new interchange would be needed along I-84 between Nampa and Caldwell. The analysis concluded widening I-84 and improving existing interchanges at Karcher/Midland (in Nampa) and Franklin Road (in Caldwell) will serve the needs of traffic beyond the design year 2045.
The overpass must be replaced to make room for current widening I-84 between Caldwell and Nampa.
Improvements include:
The Ustick Road Overpass is expected to re-open in late Summer 2023.
Traffic will be detoured from Middleton Road to Nampa-Caldwell Boulevard. Click here for a detour map.
ITD closed the intersection of Ustick Road and Aviation Way to raise the elevation of the intersection to match the height of the new Ustick Road Overpass. The Ustick Road Overpass will be higher to increase the vertical clearance on I-84.
ITD has worked closely with emergency responders in the area to ensure they have adequate access routes in the event emergency services are needed.
