Looking east

The bridge crosses over parking south of the American Royal complex and joins city streets on the bluff. Branching off to the right is a new ramp.

23rd Street Viaduct
Posted August 21, 2013, by Nathan Holth (form3 [at] historicbridges [dot] org)

This bridge has a very unusual detail at the eastern end where the truss is cantilevered out beyond the pier where it holds one end of a deck plate girder span. This is an extremely interesting bridge.
