Sonoma residents can now enjoy 30 miles of uninterrupted carpool lane travel thanks to funding from SB 1 and Measure M
SONOMA COUNTY – Caltrans and the Sonoma County Transportation Authority (SCTA) held a ribbon-cutting today to celebrate the completion of the Petaluma Widening Project that adds carpool lanes to a four-mile stretch of Highway 101 between Lakeville Highway and Old Redwood Highway in Sonoma County. The three-year, $122 million project includes $85 million in funding from Senate Bill (SB) 1, the Road Repair and Accountability Act of 2017, and $37 million in funding from Sonoma County’s Measure M.
Attending the celebration were U.S. Congressman Jared Huffman, California State Senator Mike McGuire, Petaluma Mayor Teresa Barrett, Caltrans Director Tony Tavares, SCTA Executive Director Suzanne Smith, and Tim Salles of Ghilotti Construction Company.
The Petaluma Widening Project is one of 12 widening projects in the larger Marin-Sonoma Narrows (MSN) Project to add carpool lanes between Novato in Marin County and Petaluma in Sonoma County.
The Marin-Sonoma Narrows Project is often referred to as a “gap closure” project, as it closes a 17-mile gap in the Highway 101 carpool lanes between Novato and Petaluma.
The Petaluma Widening Project is the northernmost of the MSN projects connecting a four-mile stretch of carpool lanes between the Marin-Sonoma border and Lakeville Highway and a 22-mile section of carpool lanes between Old Redwood Highway and downtown Windsor. Closing this gap creates 30-mile carpool lanes in each direction.
“Completing the Sonoma portion of the Marin-Sonoma Narrows Project will benefit the residents of Petaluma and the greater Bay Area,” said Caltrans Director Tony Tavares. “Our continuing strong partnership with SCTA has helped make this project possible.”
“This final piece of Hwy 101 improvements in Sonoma County caps a two-decade effort to complete carpool lanes from Petaluma to Windsor,” said Suzanne Smith, Executive Director of Sonoma County Transportation Authority. “Thanks to voters who approved local funds, as well as our partners in the Bay Area, the State, and Washington DC, we now have reliable and improved infrastructure that will support the movement of people and goods. The Petaluma Widening Project completes a $1.2 billion Sonoma County plan for Highway 101 between Petaluma and Windsor to boost transit and carpool use, improve highway safety and traffic operations at interchanges, and support evacuations during emergencies.”
SB 1 provides $5 billion in transportation funding annually, shared equally between the state and local agencies. Road projects progress through construction phases more quickly based on the availability of SB 1 funds, including projects that are partially funded by SB 1.
