I-15/I-86 System Interchange daytime detour to continue Wednesday morning

POCATELLO – Due to recent inclement weather, the daytime closure of the north-to-west ramp at the System Interchange will continue into Wednesday. The additional time is needed to complete placement of the steel girders for new bridges.

Traffic will be directed to the Northgate Interchange, adding approximately five minutes to travel times. Drivers will exit at Northgate, cross over I-15, and then proceed south on I-15. The detour will be in place starting at 5 a.m. until work is be completed. The same detour has been in place for the last 3 weekdays.

Girders are horizontal steel beams designed to support the bridge deck. As the beams are placed over the northbound to westbound ramp it is necessary to close the roadway beneath for the safety of the travelling public.

Ongoing construction at the System Interchange will improve safety and mobility while replacing bridges built in the 1960s. Work is expected to be complete in 2025.

Motorists should exercise additional caution while travelling through the construction zone.
