The Portland–Columbia Pedestrian Bridge (formally known as the Portland-Columbia Toll Supported Pedestrian Bridge) is a footbridge that crosses the Delaware River, at Portland, Pennsylvania, connecting to Columbia, in Knowlton Township, New Jersey, United States.

The original structure was a four-span timber bridge with wooden arches which was covered by a wooden shed with a slate roof.

In August 1955, during the remnants of Hurricane Diane, three of the four spans of the timber bridge washed away.

Hurricane Diane was the wettest hurricane to ever hit the North American continent and caused record flooding throughout the northeastern US, but particularly the Delaware River watershed.

In 1996, new guide rails were added and an ADA-compliant access ramp was built on the New Jersey side.
