It's hard to take a bad photo of this bridge. Standing on the north embankment provides a nice view of the four-banded barrier rail and the pedestals supporting electric power for the train.
Like the nearby 16th Street Bridge, this structure is a city street on the south side and becomes an expressway (State Route 160) on the north side of the bridge. It touches ground briefly north of the American River before becoming a 14 span viaduct over streets, Union Pacific tracks, bike trails, parkland, etc.
