CONSTRUCTION UPDATE & PHOTOS

Timeframe: March 23 - April 5, 2025 *2-week update
​
 

Spotlight: For the Santa Barbara North segment, crews will take geotechnical borings and pothole for utility locations to gather information for engineering design. In the Santa Barbara South segment, crews will continue removing old pavement and work on new drainage improvements. On Coast Village Circle, 24 parking spots will close for drainage improvement work. In Montecito, work continues on bridge safety barriers, and crews will pour the asphalt base layer for the northbound lanes. In the Padaro segment, crews are finishing up minor work. 

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 areas. Please expect day and night work.

  • On-ramp at Posilipo Ln, closed until spring 2026, drivers can use the southbound on-ramp at Sheffield Dr

​

• N Jameson Ln

  • 9:00 am - 3:00 pm, Mondays - Fridays, flaggers will direct traffic as needed on N Jameson Ln between Sheffield Dr and Olive Mill Rd to enable crews to move equipment and materials

​

• Coast Village Circle

  • 24 parking spaces will be closed and concrete safety barrier will be placed to enable crews to work on drainage improvements

​

• Cabrillo Blvd by Hwy 101

  • Mar 24 - 26, 6:30 pm to 6:00 am, 1 lane on Cabrillo Blvd (near Hot Springs roundabout), northbound traffic can use the Hot Springs roundabout, Old Coast Hwy, and Salinas St as a detour

  • Mar 26 - 28, 6:30 pm to 6:00 am, flaggers will direct traffic as needed on Cabrillo Blvd by Hwy 101 as crews take borings for engineering design information.

Please note: consecutive ramps in the same direction will not be closed at the same time (unless where noted) to allow drivers to use a ramp before or after a closure. 

Highway 101: Santa Barbara North

The Santa Barbara North segment is located between Hermosillo Rd and Sycamore Creek. The project team is working on design for this segment.

​

• Crews will take borings and pothole for utilities in the shoulder of Hwy 101 and along Cabrillo Blvd for engineering design information. 

 

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).
 

• Northbound Hwy 101

  • Crews will continue removing old roadway and constructing drainage improvements. 

• Coast Village Circle

  • Crews will continue drainage improvements. Crews will be removing vegetation, installing a temporary barrier, and performing utility work. Twenty-four parking spaces will be closed for this work.

• Northbound off-ramp at Hermosillo Rd

  • Crews will remove old roadway, install lighting and signage, and work on drainage improvements.

 

Highway 101: Montecito

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

• Highway 101

  • Northbound freeway lanes

    • Crews will construct safety barriers along the lanes, install drainage improvements, and pour an asphalt base layer for the new northbound 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 on-ramp at San Ysidro Rd

  • Crews will continue installing cobblestones in the area between the ramp and freeway (see photo above). 

• Romero, San Ysidro, and Oak Creek Bridges

  • Crews will continue constructing safety barriers for the new bridges.

 

Highway 101:  Padaro

The Padaro segment is located between North Padaro Ln and Santa Claus Ln.

​

• Highway 101

  • Crews have opened both the northbound and southbound carpool or HOV (high occupancy vehicle) lanes and will complete minor improvements throughout the project area. 

• N Padaro Interchange

  • Concrete Mix Site: 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.
