Timeframe:  June 13 - 26, 2021 *2-week update 

Closures (weather and COVID-19 precautions permitting)
*Please remember to Slow for the Cone Zone and use care throughout the construction zone. The speed limit is reduced to 55 mph for safety throughout the construction areas. Two lanes remain open in each direction during daytime hours.*


  • Northbound Highway 101

    • Sunday nights, 9:00 pm - 5:00 am, 1 lane:  Bailard Ave to Sheffield Dr, on- and off-ramps at N Padaro and Santa Claus Ln 

    • Monday - Thursday nights, 8:00 pm – 5:00 am, 1 lane: Bailard Ave to Sheffield Dr, on- and off-ramps at N Padaro and Santa Claus Ln  

    • week of June 20th:  Sunday night - Thursday, off-ramp at Santa Monica Rd closed, 8:00 pm - 5:00 am and 9:00 am - 3:00 pm

      • Please note that consecutive ramps in the same direction will not be closed at the same time.

    • On-ramp at Casitas Pass Rd, closed for up to 10 weeks, anticipated reopening August 2, drivers can use the newly improved northbound on-ramp at Linden Ave as a detour

      • The project team has identified a way to provide the permanent on-ramp improvements early and respond to community requests. Please note that in order to accelerate this work, the overall closure will increase up to 10 weeks rather than the previously scheduled five week closure. The closure timeframe is based on building the new roadway areas on Highway 101 that will connect to the updated ramp.

  • Southbound Highway 101

    • Sunday nights, 10:00 pm - 7:00 am, 1 lane:  Sheffield Dr to Casitas Pass Rd, on- and off-ramps at N Padaro and Santa Claus Ln, off-ramp at Casitas Pass Rd

    • Monday - Thursday nights, 8:00 pm – 7:30 am, 1 lane:  Sheffield Dr to Casitas Pass Rd, on- and off-ramps at N Padaro and Santa Claus Ln, off-ramp at Casitas Pass Rd

    • On-ramp at Sheffield Dr, closed for the duration of the project, anticipated reopening 2023, drivers can use the southbound on-ramps at Wallace Ave and N Padaro Ln

    • Off-ramp at Sheffield Dr, closed for up to 16 months, anticipated reopening end of 2021, drivers can use the southbound off-ramp at San Ysidro Rd

    • Upcoming ramp closure: On-ramp at Wallace Ave, closed as early as June 29, anticipated reopening Nov. 1

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

  • Highway 101 (median and fast lane areas in the construction zone)

    • Crews are installing rebar and concrete as part of the Continuously Reinforced Concrete Pavement (see photo above) in the median. Please note that crews will shift lanes to this new median area the week of June 27 after concrete work is completed.

  • Sheffield Drive Interchange

    • Work will continue on the retaining walls, bridge span, approach areas, and safety barriers. Crews are also erecting temporary supports for the new northbound Highway 101 bridge.

    • Homeless Encampments 

      • Crews will notice and then clear homeless encampments in the cliff between the freeway and the railroad over the next few weeks. This work is to prepare for upcoming freeway improvements on the southbound side. Please expect to see a crane and large equipment in the area to remove debris.

    • Trees & Cormorants (near southbound Hwy 101)

      • The Highway 101: Carpinteria to Santa Barbara project has employed measures to balance effective freeway construction with environmental protections specifically related to cormorants, a protected bird species. The plan relies heavily on visual deterrents and human presence to help significantly reduce or eliminate the use of air blasts. Please expect to see biologists monitoring the area daily and tree crews rotating visual deterrents.

      • Trees will remain as part of the longterm habitat. 

  • Evans Avenue Undercrossing

    • Crews will work on connecting the structures with closure pours. Crews will also work on approach areas.

  • N. Padaro Interchange

    • Concrete recycling continues.


Highway 101:  Padaro

  • Highway 101

    • Crews will pave Highway 101 shoulder areas and then shift lanes to create a work area in the median. 

    • Crews will clear and grub vegetation.

    • Arroyo Parida Creek Bridge

      • Crews will install a creek diversion system in preparation for upcoming bridge work.

    • N. Padaro Interchange

      • Crews will clear and grub vegetation, grade, and pave near the southbound Highway 101 on-ramp at N. Padaro Ln in preparation for the concrete mix and support site (drawing shown above). By mixing concrete on-site, the project:

        • reduces truck trips by 6-16 miles per trip, saving an estimated 463,771 truck miles for the Carpinteria, Padaro, and Summerland segments

        • reduces water use by 400,000 gallons (concrete mixed on-site uses less water)

        • reduces off-site neighborhood impacts

        • saves taxpayers between $10-$15 million 

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

Highway 101:  Carpinteria

  • Highway 101 & Ramps

    • Northbound Hwy 101 & Ramps

      • Crews are excavating, installing recycled concrete as roadway base, paving asphalt, installing rebar, and pouring new concrete for the freeway lanes as part of the new Continuously Reinforced Concrete Pavement.

      • Casitas Pass Rd On-ramp

        • Crews are building the wider freeway and connecting the new on-ramp.

      • Crews are installing new drainage features throughout the project.

    • Southbound Hwy 101 & Ramps

      • Crews will be working on guardrail, vegetation control, and minor adjustments. 

  • Franklin and Santa Monica Creek Bridges

    • Crews will excavate soil and install underground supports (piles) for the new wing walls and sound wall over each bridge. Removal of the old bridge sections continues.

  • Sound walls (northbound Hwy 101)

    • Near Franciscan Court & north of Cravens Lane, between Franklin Creek & Santa Ynez Ave, between Santa Ynez Ave & Santa Monica Creek, and north of Santa Monica Creek (see photo above).

      • Crews are installing underground supports (piles), constructing the wall footings, installing rebar, and placing concrete blocks.

      • Please expect noise during daytime pile driving to install underground supports.

    • Near Via Real (by Rancho Granada Mobile Homes & San Roque Mobile Estates)

      • Utility relocations are ongoing in preparation for the planned sound wall.

    • Overhead signs

      • Crews will continue excavating and driving piles for new overhead signs. Please expect noise during daytime pile driving.

Highway 101: Carpinteria to Santa Barbara is a project undertaken by Caltrans and SBCAG in cooperation with local agencies to add a new carpool lane in each direction between Carpinteria and Santa Barbara. The project will improve bridges, interchanges, on- and off-ramps, and add sound walls.
