The End of Highway 37

Signs at California 37 exit from eastbound Interstate 80 in Vallejo

The eastern endpoint of California 37 is at its interchange with Interstate 80 in Vallejo. The other endpoint is at US 101 in Novato. In this photo, taken in May 2009, note the mix of the old-style button reflector sign (the darker sign for Interstate 80) sign and the new-style reflective sign with an exit number.
