Northbound I-15 will be reduced to one lane at the 15/91 interchange nightly on:
- Friday, May 31 from 9 p.m. to 6 a.m.
- Saturday, June 1 from 10 p.m. to 6 a.m.
- Monday, June 3 from 10 p.m. to 4 a.m.
The northbound I-15 Magnolia Ave. on-ramps will also be closed during these times. The westbound and eastbound 91 connectors will remain open.
The closures will allow crews to place concrete girders at the E. Corona Overhead Bridge over the BNSF rail yard to widen the bridge for the 15 Express Lanes project.
Motorists should expect significant delays and allow extra travel time during these nighttime closures. We apologize for any inconvenience.
