US-based Granite has secured a contract worth about $114m from the California Department of Transportation (Caltrans) to deliver Segment 4E North of the Highway 101 Carpinteria to Santa Barbara Construction Manager/General Contractor (CM/GC) programme.
Segment 4E North forms part of a multi-year programme to modify US Route 101 in Santa Barbara County with the stated aim of increasing safety and reducing congestion.

Under the latest contract, Granite will replace existing lanes and construct a new peak-period carpool lane in each direction between Hermosillo Road and Salinas Street.
The company plans to start work in April 2026 and reach completion in December 2028.
The scope includes the reconstruction of the Cabrillo Boulevard interchange.
The project will introduce two new bridges and right-hand freeway ramps in place of the current left-hand ramps.
Plans for Cabrillo Boulevard include a teardrop-shaped roundabout at the intersection with the northbound Highway 101 ramps, designed to improve traffic flow through the junction.
Segment 4E North is identified as the seventh and final mainline segment in the Highway 101 Carpinteria to Santa Barbara CM/GC programme.
Granite’s Santa Paula hot plant is scheduled to supply 15,700t of hot mix asphalt.
An on-site batch plant will produce about 7,000 cubic yards of concrete using aggregates from Granite’s Bee Rock quarry, and the company will also generate roughly 30,000t of recycled aggregate base on site with a portable crusher.
Granite regional VP Larry Camilleri said: “We are proud to be part of this landmark effort with Santa Barbara County Association of Governments and Caltrans to complete the final mainline segment in the 11-mile corridor.”
The new award builds on Granite’s earlier work under the CM/GC contract.
In August 2024, Caltrans awarded the company an approximately $38m contract for Segment 4E South to add peak-hour high-occupancy vehicle lanes and reconstruct elements of the existing Highway 101 through southern Santa Barbara.
In October 2025, Granite began rehabilitation work on the historic Lake Street Bascule Bridge in Chicago, Illinois, under a contract worth about $138m awarded by the Chicago Department of Transportation.
