Found one not in the C.G. list probably because it's welded & weights removed: Sacramento Canal (between the deepwater harbor and the river) for Jefferson Blvd and the Sacramento Northern (still tracks on it, but it's abandoned just south of the bridge with tracks removed --> bike lane). Parallel bridge for SB Jefferson is a fixed bridge, as is another farther west. Navigation lock just east of the bridge is still there but obviously (in Google) hasn't been used in a long time and the east gates (to the river) are walled off from the river. [goo.gl]
