Highway 37 is one of the worst/most dangerous/least advised roads in the Bay Area to ride on. Some of it is legal and there's a shoulder, some of it is freeway and not legal. We get this question sometimes in the NorCal forum... no one ever disagrees with this evaluation.
It sucks, but there's no good way to get from Vallejo to Marin by bike.
