Search The Pennsylvania Historic Bridge Inventory

This database was populated using raw spreadsheet files provided by Pennsylvania Department of Transportation. Many of the bridges in the database have been demolished and no longer exist. Note that due to the labeling of bridges in the inventory data, bridge searches may not work the way you expect.
