CONSTRUCTION UPDATE & PHOTOS

Timeframe: October 13 - 26, 2024 *2-week update
​
 

Spotlight: In the Santa Barbara South segment, southbound lanes have been shifted and crews continue work on the shoulders and median. 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 a new retaining wall and pavement for the northbound lane improvements. Landscaping continues in the Summerland segment with crews planting and mulching along Wallace and Lillie Aves with flagging as needed. 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. 

Closures

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. To help the pavement grinding operation in the Padaro segment, lane closures will start earlier as noted below.

To view live cameras, timelines, detours, and maps, please visit www.SBROADS.com and select the project segment or Construction Update page. 

Highway 101: Santa Barbara South
The Santa Barbara South segment is located between Olive Mill and Hermosillo Rds with median work extending up to Cabrillo Blvd (for traffic lane shifts).
 

• Crews will remove old pavement and safety barriers, grade soils, and install temporary lighting in the median, shoulder areas, and around the northbound off-ramp at Hermosillo Rd. Please expect day and night noise. The work in the median is to remove old safety barriers and pavement to enable traffic lane shifts.

Highway 101: Montecito
The Montecito segment is located between Sheffield Dr and Olive Mill Rd. 
 

• Highway 101

  • Northbound freeway lanes

    • Crews will continue work on a new retaining wall for the northbound lanes and work on new Continuously Reinforced Concrete Pavement for the new lanes.

    • The northbound freeway lanes are divided by safety barriers between Hixon and Olive Mill Rds until the summer of 2025 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 pour concrete for the shoulder and gore area between the ramp and the freeway lanes.

  • Northbound on-ramp at San Ysidro Rd

    • Crews will pour concrete for the ramp.

  • Romero, San Ysidro, and Oak Creek Bridges

    • Crews will continue installing underground bridge supports (pile driving) and working on footings for the side supports (abutments) and creek wing walls (see photo above). Please expect daytime noise. There will be noise and vibration monitoring for the duration of the pile driving. 

Highway 101: Summerland
The Summerland segment is located between Sheffield Drive and North Padaro Lane. 
 

• Landscaping

  • On Ortega Hill Bikeway, crews will continue planting with flagging as needed by the north end of the bikeway.

  • Along Wallace Ave, there will be planting and mulching with flaggers directing traffic as needed (see photo above).

  • Crews will install mulch along northbound Hwy 101 with access from Lillie Ave with flaggers directing traffic as needed.

 

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 continue to grind pavement for final smoothness and traction. Please expect night noise.

  • Crews will continue work on median safety barriers, concrete finishing, and sign installation.

• Southbound on- and off-ramps at N Padaro Ln and off-ramp at S Padaro/Santa Claus Ln

  • Crews will install concrete for improved ramp connections. The on- and off-ramps at N Padaro Ln will be closed for approximately 3 weeks (see detour maps above). The off-ramp at S Padaro/Santa Claus Ln will remain open with traffic shifted.

• 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 new sidewalks, curbs and gutters, lighting, and irrigation under and around the bridge. 

• N Padaro Interchange

  • Concrete Mix Site:  Oct 13 - 26, 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.
