NORTHBOUND (NB) AND SOUTHBOUND (SB)

I-15 JURUPA STREET EXTENDED RAMP CLOSURES

As the freeway is widened to accommodate the future Express Lanes on I-15, on- and off-ramps will be closed for an extended period to allow for realignment and repaving. Work will take place during daytime and nighttime hours. Detour routes will be posted.

• NB I-15 Jurupa Street on-ramp is scheduled to close Sunday, November 30 at 11:59 p.m. through Monday, December 15 at 5:00 a.m.

• SB I-15 Jurupa Street on-ramp is scheduled to close Wednesday, December 3 at 11:59 p.m. through Thursday, December 18, at 5:00 a.m.

Please plan ahead, allow extra time to reach your destination, and follow all construction signage.

Construction activities continue along the I-15 corridor, including sound wall and retaining wall construction, paving removal, sign installation, bridge reconstruction, and other improvements to support a wider freeway footprint. Concrete barriers (k-rail) remain in place along freeway and ramp shoulders to create safe work zones.

What to Expect:

• Daytime and nighttime work may impact traffic flow and travel time.
• Expect intermittent ramp and freeway lane closures. Please allow extra time to reach your destination.
• Drive with caution; watch for signage, construction vehicles, and crew members throughout the corridor.
• Reduced speed limits are strictly enforced in construction zones to protect both drivers and workers.

Construction will generally occur Monday through Friday during daytime (6:00 a.m. to 4:00 p.m.)

and nighttime (9:00 p.m. to 5:00 a.m.) hours. All construction is dynamic and subject to change. Please check the Google Map for the most updated closure and detour information.

Caltrans began a $14.7 million bridge improvement project at the I-15/I-10 connector in Ontario in July 2025. This project will upgrade bridge rails, a bridge deck, drainage systems, ramp meter infrastructure, and maintenance pullouts.

Crews are building a wider section of the NB I-15 over 6th Street.

The I-15 Corridor Freight and Express Lanes Project is a collaborative effort by the San Bernardino County Transportation Authority (SBCTA) and the California Department of Transportation (Caltrans) in coordination with the Riverside County Transportation Commission (RCTC). The 8-mile project from Cantu-Galleano Ranch Road in Jurupa Valley to just north of Foothill Boulevard in Rancho Cucamonga will add express lanes in the median of I-15 to join the existing express lanes in Riverside County and add auxiliary lanes to improve traffic operations and safety in the vicinity of the I-15/SR 60 and I-15/I-10 interchanges.
