Detour tonight at Fort Hall (Exit 80) Interchange

Fort Hall Construction , I-15, Exit 80

POCATELLO – Aug. 28, 2023 | Southbound drivers on I-15 will be detoured through the interchange ramps at Fort Hall (Exit 80) tonight from 9:30 p.m. to 5 a.m. This will allow crews to operate safely as they work on the bridge beams over the roadway.

The Fort Hall Interchange is undergoing a complete reconstruction to replace the outdated bridge and improve on- and off-ramps. The redesign also allows for the planned three lanes northbound and southbound on I-15. Those wishing to learn more about the project can visit

Motorists should exercise caution while travelling through the work zone as traffic patterns will continue to change over the next week to accommodate construction. Drivers can also check or download the 511 app for the last traffic conditions on all state highways and freeways.
