I-15 traffic to be diverted for Northgate bridge construction

There will be a new challenge for Interstate 15 travelers at the new Northgate Interchange near Pocatello beginning Tuesday night.

The Idaho Transportation Department will divert northbound traffic onto US 91 while girders are placed at the new interchange. The work is planned between 10 p.m. and 5 a.m.

Drivers will exit on I-86 at Exit 61 (Chubbuck interchange) and re-enter I-15 at Exit 89 (South Blackfoot interchange).

Traffic control will continue for the same hours Wednesday night. ITD will then divert southbound traffic on US 91. Drivers will exit I-15 at Exit 89 and re-enter at Exit 61 on I-86. Traffic control will be set up at the Fort Hall interchange to divert traffic as needed.

The work is part of a year-long project to construct the new Northgate interchange on I-15. That project should be complete by late fall.
