SH-24/US-30 closure planned under I-84 (Exit 211) - watch for detours this weekend

HEYBURN-The Idaho Transportation Department is closing State Highway 24/U.S. Highway 30 under Interstate 84 at Exit 211 from Friday, April 4, at 6 p.m. through Monday, April 7, at 6 a.m. The closure is necessary to remove the old I-84 bridge as part of the ongoing reconstruction of the Heyburn Interchange.

Detours will be in place to guide motorists through the project area and is expected to add 10 minutes to commutes. Speed limits have been reduced to 65 mph on I-84.

Reconstruction of the Heyburn Interchange is expected to cost $90.1 million and last until late 2026. Since work began in 2024, construction of half of the westbound bridge over US-30, an embankment for the future interchange and center pier for the future interchange structure have been finished.

The next phase of the project includes the removal and construction of the eastbound structure over US- 30, removal and construction of the eastbound road and construction of the south half of the interchange.

Built in the early 1960s, the interchange has reached the end of its service life. ITD is focused on improving safety, mobility, and economic opportunity for all users who travel these important agricultural and industrial routes.

Construction is being funded as part of Idaho Governor Brad Little's Leading Idaho transportation funding initiative. The Leading Idaho initiative allows ITD to take a deliberate approach to advance large projects that will enhance safety, improve mobility, further strengthen Idaho's economy, and positively impact the Magic Valley and communities across the state for years to come.
