Rockville Bridge

Rockville Bridge is a railway bridge crossing the Susquehanna River near Marysville, built with 48 stone arches that support two parallel railroad tracks. The structure stretches roughly 1,200 meters and connects both river banks with a solid stone construction.

Construction of this Pennsylvania Railroad bridge began in April 1900, replacing an earlier iron structure that had previously spanned the river. The new stone arch bridge opened for railway traffic in March 1902.

The National Register of Historic Places recognizes this engineering achievement as the longest stone arch railroad viaduct constructed in the world.

Trains operate daily across the bridge, so visitors should view the structure from safe vantage points along the river or nearby areas. The best viewing spots are from the riverbank paths or parking areas near Marysville.

Some of the arches were built using sandstone from Clearfield County, a special material that helped the structure endure for over a century. This choice of local stone made the construction more economical and influenced how well the bridge has aged.
