The southbound (SB) Fourth Street on- and off-ramps are scheduled to be closed for 15 continuous days for ramp realignment and paving beginning:

• Sunday, September 27 at 9:30 p.m.: SB I-15 off-ramp at Fourth Street
• Monday, September 28 at 9:30 p.m.: SB I-15 on-ramp at Fourth Street

Detour routes will be posted. Please allow extra time to reach your destination and follow all posted signage. Dates are subject to change.

Construction activities continue along the I-15 corridor, including sound wall and retaining wall construction, concrete and asphalt paving operations, bridge reconstruction, and other improvements to support a wider freeway footprint. Temporary barriers (k-rail) remain in place along freeway and ramp shoulders to create safe work zones. Motorists should also be aware of upcoming traffic shifts, which may move lanes toward the median.

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.
• Work may be loud and cause vibrations at times.

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.

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.
