I-84 Eastbound Off-Ramp in Boise to Close Overnight for Ramp Work

Boise, ID, September 22, 2026 —

The Idaho Transportation Department (ITD) has announced a planned overnight closure for the Interstate 84 eastbound off-ramp at the South Jerome Interchange in Boise. The closure is scheduled to begin on Tuesday, September 22, at 7:00 p.m. and is expected to last until Wednesday, September 23, at 6:00 a.m.

The purpose of this closure is to facilitate work on a new permanent ramp. During the closure period, motorists seeking to exit I-84 eastbound at this location will be directed to follow a detour. The designated detour route will guide drivers to the Main Street/SH-25 Interchange, identified as Exit 165. Additionally, drivers should be aware that Lincoln Avenue will undergo a temporary shift in its configuration to accommodate the ongoing construction activities.

This work is part of an ongoing project to improve the infrastructure at the South Jerome Interchange. Commuters and local traffic in the vicinity are advised to plan for potential delays and to follow posted detour signs carefully. The exact contractor performing the work was not provided in the summary. Information regarding any specific traffic impacts beyond the ramp closure and Lincoln Avenue shift was not detailed. The duration of the project was not specified beyond this immediate closure.

Authorities recommend that drivers allow for extra travel time, especially during peak commute hours at the beginning and end of the closure window. Further updates on traffic conditions or any changes to the schedule are expected to be released by the ITD. The specific timeline for the completion of the new permanent ramp was not provided.
