The Idaho Transportation Department plans to open new lanes on Interstate 84 after shifting traffic near the Twin Falls Interchange (Exit 173) on Friday and Saturday nights (Nov. 13-14). When the shift is completed, I-84 will open to its final configuration of:
- Three lanes in each direction west of the interchange.
- Two lanes in each direction east of the interchange.
Motorists can expect:
- Eastbound I-84 traffic will shift between 8 p.m. and 6 a.m. on Friday night (Nov. 13).
- Westbound I-84 traffic will shift between 8 p.m. and 6 a.m. on Saturday night (Nov. 14).
- The loop westbound on-ramp at the Twin Falls Interchange will close between 8 p.m. and 6 a.m. on Saturday night (Nov. 14) to allow crews to safely shift traffic. Motorists will use the other westbound on-ramp to enter westbound I-84.
This work is weather-dependent and may be delayed due to conditions. Intermittent I-84 lane closures will continue through the end of the project in late November.
Construction began in 2023 to improve safety and capacity in the project area by widening I-84 to three lanes in each direction. As crews wrap up work on the project, motorists are encouraged to leave early, follow signage and pay attention when traveling in the work zone. Visit 511.idaho.gov to plan your route in advance.
