CONSTRUCTION UPDATE & PHOTOS

CONSTRUCTION UPDATE 
Timeframe: July 13 -26, 2025 *2-week update
 

Spotlight:  In Montecito and Santa Barbara South, the updated northbound lanes between Sheffield Dr and Hermosillo Rd, a new northbound auxiliary lane between San Ysidro and Olive Mill Rds, improved on-ramp at San Ysidro Rd, and off-ramp at Hermosillo Rd are open. On the night of July 12, the southbound freeway lanes between Olive Mill Rd and Posilipo Ln will move to the median and be divided by safety barriers for the next stage of construction through summer 2026. The southbound on-ramp at Olive Mill Rd will close and remain closed for 9 months. The southbound off-ramp at San Ysidro Rd will close for 3 months. See detour maps below.

In Summerland, crews will pressure wash and stain concrete barriers.  In Padaro, landscaping crews will be installing irrigation in the vicinity of Toro Creek. 

Closures (weather permitting)
