Replacing the Middleton and Ustick overpasses will make room for expanding I-84 in Canyon County.
The Middleton and Ustick overpasses were built in 1966 and do not allow room for additional lanes on I-84. The Idaho Transportation Department is making plans to replace both overpasses in 2020.Read More
The Middleton and Ustick overpasses are located on I-84 between the Franklin Road and Karcher Road interchanges. This work is part of ITD’s long-term vision for expanding I-84 from Nampa to Caldwell.
In 2018, the Federal Highway Administration accepted a proposal from ITD to complete the environmental study in smaller parts. This allowed ITD to move forward with designing improvements between Franklin Road and Karcher Road, including the Middleton and Ustick overpasses.
A traffic analysis was completed in 2018 for this area of I-84. The study included a detailed review of future traffic needs.
The analysis concluded that future traffic needs will be addressed by widening I-84 and improving existing interchanges.
