Construction Updates

As part of our ongoing effort to keep the community up to date on the Highway 101: Linden and Casitas Pass Project, we send out regular project construction updates via email. The following is the current construction update.


July 22 - 29, 2018

Scheduled Construction

REVISED: On Monday and Thursday nights, July 23rd and 26th, both northbound freeway lanes and one southbound lane will be closed from 10:00 pm to 5:00 am. One southbound freeway lane will remain open.

Please note on Tuesday and Wednesday nights, one northbound and one southbound Highway 101 lane will be closed between 10:00 pm and 5:00 am. One freeway lane in each direction will remain open. Details below...

Mario shows off test samples of the finishes for the new retaining walls (left and right)
and side supports of the new overcrossings (center).

Linden Avenue Overcrossing

  • Crews will remove the underground supports (piles) from the old Linden Avenue Overcrossing. Following removal of old piles, crews will drive new piles for the new center support (bent). Pile driving will occur from 7:00 am to 7:00 pm to limit nighttime noise. After that, dirt will be removed from the new pile and a rebar cage installed prior to a cement pour.
    • Restringing the crane, removing old piles, equipment delivery, and realignment of the large crane will occur at night.
      • Northbound Highway 101 and the southbound fast lane will be closed on Monday night, July 23rd, from 10:00 pm to 5:00 am between Linden and Bailard Avenues. One southbound lane will remain open. Please see the map below for northbound detours.
      • The northbound and southbound Highway 101 fast lanes will be closed nightly as needed from Tuesday to Thursday, July 24th - 26th, from 10:00 pm to 5:00 am between Linden and Bailard Avenues. One lane in each direction will remain open during this work.
  • Southern California Edison crews will be working on electrical lines near Linden Avenue.
  • Concrete has been poured for the side support (abutment) footings for the new bridge. Rebar and wood form work continues on the walls.

Casitas Pass Road Overcrossing

  • With the old overcrossing removed, work will progress to excavation for the side supports (abutments) for the next new bridge section.

Highway 101

  • Carpinteria Creek Bridges
    • Concrete has been poured for the new side supports (abutments). Crews continue installing temporary supports (falsework) for the new bridges. Rebar installation begins for internal supports (stems) and the underside (soffit) of the bridges.
      • Setting falsework will require some night work due to the length of the beams.
        • Northbound Highway 101 will be closed on Thursday night, July 26th, from 10:00 pm to 5:00 am from Bailard to Linden Avenues. Please see the temporary northbound Highway 101 detour on the map below.

  • Northbound Highway 101 sound wall between Linden Avenue and Franklin Creek (Nipomo Drive)
    • Southern California Edison has been connecting underground utilities and will remove old poles and overhead wires. This is part of the overall utility relocation that needs to occur prior to the sewer line relocation and sound wall construction.
  • Southbound Highway 101 sound wall between Linden Avenue and Casitas Pass Road
    • Soil backfill continues, and crews will remove shoring piles used for construction of the retaining wall.
  • Electrical work throughout the project will be ongoing for new street lights and traffic signals.
  • Drainage improvements are beginning along northbound Highway 101 under the Casitas Pass Overcrossing.

Via Real

  • Please note that Via Real will only have 1 northbound lane open between Casitas Pass Road and Vallecito Road for the next few months. See map below.
    • Crews will be working on a retaining wall on Via Real between Hales Lane and Casitas Pass Road.

Upcoming Work: summer/fall

  • The Highway 101 southbound off-ramp at Casitas Pass Road will close for up to 1 month. Detour maps can be viewed at

Carpinteria Valley Water District will install a new water line on Linden Avenue.
