Construction Update

Timeframe: July 7 - 20, 2024 *2-week update

Spotlight:  In Montecito, the southbound off-ramp at San Ysidro Rd has reopened and the southbound on-ramp at Posilipo Ln is closed through spring 2026. The divided northbound lanes between Hixon and Olive Mill Roads (shown in the graphic below) will start July 20 along with the closure of the northbound off-ramp at San Ysidro Rd. During the lane shifts, please expect both the northbound off-ramps at San Ysidro and Olive Mill Rds to be closed as crews move concrete safety barriers. Once the lanes are shifted, the northbound off-ramp at Olive Mill Rd will reopen. In Summerland, planting continues along the southbound lanes by the southbound off-ramp at Evans Ave and Greewell Creek. Irrigation work continues on the northbound side. In the Padaro segment, crews will continue working on new median safety barriers and drainage improvements. Crews will remove concrete barriers by the southbound on-ramp at Santa Claus Ln (see night closures below).

Closures (weather permitting)

Please drive safely through the corridor and remember to Slow for the Cone Zone. The speed limit is reduced to 55 mph for safety throughout the construction areas. Two freeway lanes remain open in each direction during daytime hours. Please expect day and night work.
