The Idaho Transportation Department is evaluating improvements to Interstate 84 between Caldwell and Nampa. This is part of a plan to invest more than $300 million into I-84 in Canyon County over the next several years.
This project includes a traffic study and environmental evaluation. ITD is considering potential impacts to adjacent properties, minority populations, noise, floodplains, wetlands and many other factors. Public input is a key element of the study.
ITD has developed long-term alternatives for improving the section of I-84 between Centennial Way and Franklin Road in 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/Midland Road.
ITD is designing an additional interstate lane in each direction between Franklin Road in Caldwell and Karcher/Midland in Nampa. To add lanes on I-84, the Middleton and Ustick overpasses must be replaced.
More information will be available at an open house later this summer.
ITD has allocated more than $300 million in state, federal and GARVEE funds to improve I-84 in Canyon County. $150 million of this funding has been allocated to the section of I-84 between Caldwell and the Karcher Interchange in Nampa.
This funding will cover the environmental study and traffic analysis for the entire corridor. It also will cover design and construction between Franklin Road and Karcher. Additional funding will be needed to design and construct the improvements west of Franklin Road.
