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 interchanges at Karcher/Midland (in Nampa) and Franklin Road (in Caldwell) will serve the needs of traffic beyond the design year 2045.
The Idaho Transportation Department is constructing improvements to Interstate 84 between Franklin Road (Exit 29) in Caldwell and Karcher Road (Exit 33) in Nampa.
The work is expected to improve mobility, increase safety and benefit the regional economy for many years.
