Travel Impacts Updated April, 2020
Through-travelers on I-84 have been shifted onto a temporary detour bridge during construction and should experience relatively little disruption. I-84 travelers will experience eastbound and westbound daytime and nighttime single-lane closures with related slowdowns, traffic control devices, and lane shifts at various times during the project. Brief, full closures of I-84 may be needed during demolition of the temporary detour bridge. Speed limits in the work zone will be reduced to 50 mph during construction.
When necessary, expect:
- Periodic single-lane closures on I-84 eastbound and I-84 westbound.
- Full directional and ramp closures from 9 p.m. to 6:30 a.m. on weeknights.
- Full directional and ramp closures from 10 p.m. to 8 a.m. on weekends.
Detours
- When westbound I-84 is closed, traffic will be routed onto NW Frontage Road (North).
- When eastbound I-84 is closed, traffic will be routed onto NW Frontage Road (South)
