Construction Update & Cameras
Timeframe: September 27 - October 10, 2026
Spotlight: In Montecito, crews are continuing to prepare Highway 101 for the opening of new carpool lanes in the northbound and southbound directions. Activities leading up to the opening will include pavement grinding, expected to begin by mid-October. This work will be performed at night and will generate noticeable construction noise. Santa Barbara North and Santa Barbara South will experience overnight lane closures to support paving and asphalt operations. In Padaro, the concrete mix site will operate overnight from Oct. 4 through Oct. 8 to support the placement of new continuously reinforced concrete pavement in the Santa Barbara South segment; please expect night noise.
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 area.
