Caltrans has a project on the drawing board to redesign the interchange at Highway 37 and Highway 121, a major chokepoint near the Sonoma Raceway.
"It's horrible, it's horrible everywhere you go." said Jennifer St. John about driving between Petaluma and Novato on Highway 101. She's thinking about moving away from the region to avoid the hassle.
"I plan my days around it," she said. "I leave as early as possible just to avoid it, and in the afternoon, I leave early so I can avoid it that way."
What commuters may not want to hear is that plans to widen Highway 37, which links Vallejo and Marin, are still at least a decade away.
