This is the drawbridge across the Sacramento River at Rio Vista. This is the southernmost crossing of the Sacramento that is bike-legal.
Mount Diablo forms a background for the Sacramento River.
A drawbridge on highway 160, which crosses onto Sherman Island.
The Antioch bridge, across the San Joaquin River. Unfortunately, I had pulled off onto the shoulder to take this picture, which was covered with sharp quartz-like gravel. I got a flat tire as I pulled back onto the road. :-(
