At long last, the bike improvements associated with the Marin-Sonoma Narrows Project are complete. This Friday, Caltrans will officially open a new pathway underneath the US-101 / San Antonio Creek Bridge connecting frontage roads between Novato and Petaluma and establishing what will now be the most direct, flat, and safe route available between the two cities!
From the south, the new route is accessed by riding north along San Antonio Road. Once you cross the bridge over San Antonio Creek, do not take San Antonio Road where it veers left; instead, continue straight on the narrow access road until you see the pathway to the right. The pathway leads underneath the freeway and briefly parallels San Antonio Creek before exiting onto the new Petaluma Boulevard South frontage road.
