As the Northern Central Railway built north up the Susquehanna River from Baltimore, Maryland to the coal regions, it had to cross from the west to the east bank of the Susquehanna.
The chosen crossing site was at the Dauphin Narrows, between Marysville on the west and Dauphin on the east.
The bridge was finished in 1858, allowing the Northern Central to haul coal from Sunbury, Pennsylvania to Baltimore.
However, the construction of a line from Dauphin to Rockville and the takeover of the Northern Central by the Pennsylvania Railroad in 1875 resulted in most Northern Central traffic being rerouted over the PRR's Rockville Bridge a short distance downstream.

The Marysville Bridge was allowed to fall into decay, and removed in 1902 or 1903 after a period of disuse.
Some of the piers remain above water today, while others are submerged or washed away.
