CONSTRUCTION UPDATE & PHOTOS

Timeframe: December 8 - 21, 2024 *2-week update
​
 

Spotlight: In the Santa Barbara South segment, crews will continue working on drainage improvements and begin work on median temporary paving. The Butterfly Lane Undercrossing is closed Dec 2 - Dec 23 to close a ceiling grate in preparation for freeway widening. In Montecito, crews will begin drainage improvements near Olive Mill Rd and begin installing new bridge girders at Romero, San Ysidro, and Oak Creeks. Landscaping continues in Summerland. In the Padaro segment, crews will continue grinding pavement to improve traction and provide additional long-term noise reduction. Grinding will occur at night; please expect night noise. The new carpool lanes from Summerland to Carpinteria will re-open by the end of the year northbound and mid-January southbound (weather permitting). Design modifications in the Santa Barbara South and Montecito segments will be reviewed by the Architectural Board of Review and Montecito Planning Commission respectively (see details below).
