Evans Avenue Undercrossing

Flaggers will direct traffic with alternating lane closures as needed during daytime work for materials delivery and equipment movement. The majority of work will occur behind safety barriers with lanes open on Evans Ave. under the freeway bridges.

Sheffield Drive & N Jameson Lane

Temporary stop signs have been installed at the intersection of Sheffield Dr. and N Jameson Ln. for the duration of construction of the Summerland segment.

Via Real & Linden Avenue

Mon.- Wed., Feb. 22 – 24, 7:00 am – 5:00 pm: Flaggers will direct traffic as needed during the day on Via Real (between Santa Monica Rd. and Cravens Ln.) and on Linden Ave. (near the freeway) to allow crews to transplant palm trees. As needed, the northbound Highway 101 on-ramp at Linden will be closed between 9:00 am and 3:00 pm.

Highway 101: Summerland

Crews will install underground storm drains and new drainage features. Vegetation clearing will continue in preparation for upcoming improvements. Crews will remove old safety barriers from the median and then excavate old pavement and soil.

Sheffield Drive Interchange

Crews will continue to build footings, install rebar, and pour concrete for columns, side supports (abutments), and retaining walls for the new bridges in the median. Work will also continue on the bridge span (superstructure). Crews will prepare for temporary supports (falsework) needed for the next stage of construction.

Trees & Cormorants Near Southbound Hwy 101

As part of the long-term habitat and bird protection plan, biologists and arborists have removed old nests, installed visual deterrents, and will use auditory deterrents to discourage cormorant nesting within the construction area. This effort is to encourage the birds to nest outside the construction zone. At the end of the nesting season, the visual deterrents (beach-ball type balloons, flash tape, etc.) will be removed. Trees will remain as part of the long-term habitat. Biologists are on-site monitoring this effort.

Evans Avenue Undercrossing

Crews will continue to construct the new median bridge columns (see photo below) and work on the bridge span (superstructure).

N. Padaro Interchange

Concrete recycling continues.

Highway 101: Padaro

The Padaro segment is located between North Padaro and South Padaro/Santa Claus Lanes. This project will add a new third freeway lane in each direction and new bridges over Toro and Arroyo Parida Creeks. At the South Padaro Ln. undercrossing, the bridge and on- and off-ramps will be replaced. At the North Padaro Ln. interchange, new on-and-off-ramp improvements will be built. There will also be three new sound walls built.

Over the next few weeks, to comply with the California Department of Fish and Wildlife requirements related to bird nesting, crews will undertake pre-construction work to clear trees and vegetation so that construction can begin this summer. The majority of work will occur in the median and near the South Padaro/Santa Claus on- and off-ramps.

Highway 101 & Ramps

Southbound Hwy 101 & Ramps
Carpinteria & Linden Avenues’ southbound off-ramps

Crews will continue regrading (see photo above) in preparation for ramp improvements. Rebar installation and concrete pours will begin for Continuously Reinforced Concrete Pavement (CRCP).

Please use the newly reconstructed ramps at Reynolds Avenue and Casitas Pass Road as detours. Work continues on foundations and posts for new signs. Crews will drive piles for underground supports as needed for sign foundations. During pile driving, please expect loud noise during daytime work.

Sound Walls

On southbound Hwy 101 between Carpinteria & Santa Ynez Avenues, crews will continue building the wall footings and then install rebar and in-and-out blocks.
