SBCAG staff
Spotlight: The Santa Barbara South segment has begun! Construction is starting with tree and vegetation removal along the freeway shoulders and median. Please expect day and night noise for clearing and chipping.
In Montecito, crews will continue installing underground supports (pile driving) for the new bridges. Please expect daytime noise during this work. Crews will also continue work on the new northbound lanes and off-ramp at San Ysidro Rd. The northbound lanes will remain divided by safety barriers between Hixon and Olive Mill Rds through summer 2025.
Landscaping continues in the Summerland segment. In the Padaro segment, crews will grind pavement to improve traction and provide additional longterm noise reduction. Grinding will occur at night; please expect night noise.
Live project cameras are online at https://www.

Highway 101: Santa Barbara South
The Santa Barbara South segment is located between Olive Mill and Hermosillo Rds.
- Crews will remove trees and vegetation from the northbound and southbound shoulders and median. Please expect day and night noise during clearing and chipping.
- Crews will start electrical work on the southbound off-ramp at Olive Mill Rd (see photo above) and begin excavating and widening the outside freeway shoulders to prepare for upcoming lane shifts.
Highway 101: Montecito
The Montecito segment is located between Sheffield Dr and Olive Mill Rd.
- Highway 101
- Northbound freeway lanes
- The northbound freeway lanes are divided by safety barriers between Hixon and Olive Mill Rds until the summer of 2025 (see graphic below) to provide space to construct the new northbound lanes. Montecito exits are accessible from the slow lane.
- Northbound off-ramp at San Ysidro Rd
- Crews will pave and pour concrete for the new off-ramp.
- Northbound on-ramp at San Ysidro Rd
- Crews will work on drainage improvements.
- Romero, San Ysidro, and Oak Creek Bridges
- Crews will continue excavating soils, installing underground bridge supports (pile driving, see photo above), and working on footings for the side supports (abutments). Please expect daytime noise. There will be noise and vibration monitoring for the duration of the pile driving.
- Northbound freeway lanes
Highway 101: Summerland
The Summerland segment is located between Sheffield Drive and North Padaro Lane.
- Landscaping
- At the northbound on- and off-ramps at Sheffield Dr, crews will apply mulch to newly planted areas (see photo above).
Highway 101: Padaro
The Padaro segment is located between North Padaro Lane and Santa Claus Lane.
- Highway 101
- On northbound and southbound Hwy 101, crews will grind pavement for final smoothness and traction. Please expect night noise.
- Crews will continue work on median safety barriers and concrete finishing.
- Southbound on-ramp at Santa Claus Ln
- Crews will work on the cobblestone area between the freeway lanes and ramp. The ramp will also be re-striped.
- S Padaro Ln Undercrossing
- For the new bridge, crews will continue work on the slope paving and pedestrian improvements under the bridge (see photo above).
- N Padaro Interchange
- Concrete Mix Site: Sept 13 – 28, 8:00 pm – 5:00 am, crews will mix concrete. By mixing concrete on-site, the project saves an estimated 463,771 truck miles, reduces water use by 400,000 gallons (concrete mixed on-site uses less water), and saves taxpayers between $10-$15 million.
- Concrete recycling continues by the northbound Highway 101 off-ramp at N. Padaro Ln.
