Granite has secured a $114 million contract for Segment 4E North of the Highway 101 Carpinteria to Santa Barbara expansion program in California. The contract is part of a multi-year corridor improvement initiative led by California Department of Transportation and the Santa Barbara County Association of Governments.
The project involves widening US Route 101 by replacing existing lanes and adding a peak-period carpool lane in each direction between Hermosillo Road and Salinas Street. Work also includes reconstruction of the Cabrillo Boulevard interchange, with two new bridges, updated freeway ramps, and a new roundabout to improve traffic flow and safety.
Funding is provided through state and regional transportation programs supporting corridor upgrades and congestion reduction. Granite will serve as construction manager and general contractor for the segment, continuing its role across the broader Phase 4 program.
The project is in the pre-construction phase, with work scheduled to begin in April 2026 and reach completion by December 2028. This segment represents the final mainline portion of the 11-mile Highway 101 improvement corridor. The expansion aims to reduce congestion, improve traffic circulation, and enhance safety along a key coastal transportation route.
