This is an impressive pair of identical bridges that sit right beside each other. One remains in use, the other is abandoned. Both were designed to accommodate two sets of railroad tracks, accounting for their wide decks and massive appearance. The bridges are made attractive by the use of lattice on many of the built-up beams composing the structure.
These are both next to the Carson Street Bridge, making this a historic scene where two truss bridges, one highway and one railroad, sit side by side, a scene that was once common in this country, but due to demolition, mostly of the highway bridges, is hard to find today.
