Earlier bridges.
The first crossing of the Raritan at this point was wooden bridge on masonry substructure, constructed in 1838 by the United New Jersey Railroad and Canal Company. It was a long double-deck Howe truss bridge with a highway on the lower deck. The -foot long draw span was renewed in 1872.
In 1877 work began on the replacement with the intention to build a double-track iron structure of seven iron fixed deck-spans having three trusses each with stone-arch approaches. While construction was underway this bridge was entirely destroyed by fire on March 9, 1878. Traffic was resumed over a temporary structure five days later.
In 1896, the superstructure was again renewed with five deck truss-spans, each long, and one drawspan over the canal, all for two tracks.
Literary significance.
In the Pulitzer Prize winning novel The Brief Wondrous Life of Oscar Wao by Junot Diaz, the title character becomes so frustrated and despondent over the futility of his romantic pursuits that he gets drunk, walks out onto the Raritan River railroad bridge, and attempts suicide by jumping off, surviving only because he lands in the shrubs on a garden divider on Route 18. Later he regretfully explains to his friend Yunior, "It was foolish. Ill-advised."
