Overview
ITD designed the new interchanges to improve safety and keep traffic moving, meeting the community’s needs as the area grows. ITD anticipates that construction will be complete by late 2026.
Originally built in the early 1960s, the I-84 Burley (Exit 208) and Heyburn (Exit 211) interchanges reached the end of their service lives. ITD is committed to improving safety, mobility, and economic opportunities for all users traveling these vital agricultural and industrial routes.
Construction Updates
Since 2024, ITD has made significant progress on the two interchanges while also keeping the corridor open to traffic. Each interchange requires work well below the pavement and involves utilities, earthwork and more. Additionally, to keep traffic moving, work is completed in sections, so this essential corridor remains open as safely as possible.
Heyburn
ITD has constructed new on- and off-ramps at the Heyburn interchange, new structures over rail lines, stormwater systems, a new access road, and access road bridge. ITD needs to complete deck pavement, railing, and connections between ramps, bridges, and roadway before opening the road to the public.
Burley
ITD continues working to complete on-ramps and new bridges and will soon begin paving the westbound and eastbound lanes of I-84 and removing temporary roads, guardrail, curbs and gutter, fencing, traffic signal work, and signage. Construction is expected to finish in late 2026.

Community Involvement
ITD strives for meaningful public involvement by communicating project information and gathering community input.
In January 2022, ITD hosted the first in-person and online public meetings to share concept alternatives and gather community feedback on the concept designs for each interchange. Four options for each interchange were presented. ITD evaluated the alternatives by considering public feedback and technical elements.
ITD hosted the second in-person and online public meetings in March 2023 to share the selected designs for the reconstruction of the interchanges. ITD also invited key stakeholders, including elected officials and business owners, to attend an earlier session to view information and ask the project team questions. Summaries of both public meetings are available in the Resources section below.
