Construction Update & Cameras

CONSTRUCTION UPDATE
Timeframe: July 12 - August 1, 2026 *3-week update

Spotlight: Across all three project segments in construction, crews continue to make steady progress on permanent highway improvements. In Santa Barbara North, bridge foundation and retaining wall construction continues. Intermittent daytime flaggers will direct alternating one-way traffic beneath Highway 101 on Cabrillo Boulevard for equipment and material deliveries. In Santa Barbara South and Montecito, crews will continue constructing permanent roadway improvements, including storm drainage systems, bridge construction, retaining walls, and new median safety barriers. In Padaro the concrete mix site will operate overnight on July 30 to support placement of new reinforced concrete pavement in the Montecito segment; please expect night noise.
