With the completion of the Richmond-San Rafael Bridge in 1956, as well as the first segment of the Eastshore Freeway north of the Maze, SR 17 was extended northward along the new freeway in a concurrency with US 40. SR 17 left the freeway at the Hoffman Blvd. exit (thereafter popularly called the "Hoffman Split") and proceeded along city streets through Richmond to the San Rafael bridge. It went via Hoffman, Cutting, and Standard Avenue up to the bridge. It crossed the bridge into San Rafael, terminating at a junction with US 101.
