SONOMA COUNTY, CA -- Officials from Caltrans and Sonoma and Marin counties Wednesday morning celebrated both the completion and beginning of phases of the ongoing widening of U.S. Highway 101 between the two counties.

Ground was broken for the widening and realignment of the Marin-Sonoma Narrows Project segment at San Antonio Creek. This phase of the project will widen the highway by adding a carpool lane to the two existing
lanes in each direction between Novato and Petaluma. It will be completed by the end of 2018.

Caltrans spokesman Allyn Amsk said more than 500,000 cubic yards of soil will be moved during the construction.

Transportation officials also celebrated with a ribbon-cutting ceremony the completion of the Petaluma River Bridge and Kastania Road/Petaluma Boulevard South interchange and the reconstruction of the
Lakeville Highway and Redwood Landfill interchange.

The entire Marin-Sonoma Narrows project extends 17 miles between state Highway 37 in Novato and Old Redwood Highway in Petaluma. The project is being done in segments, some of which are not yet funded, Amsk said.

When completed, there will be three lanes in each direction, one of which is a carpool lane.

More information about the MSN 101 project can be found online at SCTA’s website, TAM’s website or the Caltrans District 4 website.
