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 grade soils and work on new drainage improvements.
  • Northbound on-ramp at San Ysidro Rd

  • Romero, San Ysidro, and Oak Creek Bridges
    • Crews will continue excavating soils and begin installing underground bridge supports (pile driving) on Sept 4. Please expect daytime noise. Crews will drive piles for all three creek bridges. The photo above shows progress at San Ysidro Creek. Live project cameras are online at https://www.hwy101carpinteria-santabarbara.com/construction-updates.

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

• Landscaping
  • Flaggers will direct traffic on Wallace Ave near Highway 101 to allow crews to plant large trees (see photo above to see some of the large oaks at the project site).

  • Concrete recycling continues by the northbound Highway 101 off-ramp at N. Padaro Ln.
