The South Tenth Street Bridge, most often called the Tenth Street Bridge, but officially dubbed the Philip Murray Bridge, is a suspension bridge that spans the Monongahela River in Downtown Pittsburgh, Pennsylvania.

The only cable suspension bridge that is located in Allegheny County, its 725-foot (221 m) main span is the longest on the Monongahela River.^{[citation needed]} The bridge was renamed on Labor Day 2007 for Philip Murray, the first president of the United Steelworkers of America.^[4]

Built between 1931 and 1933, this bridge connects South Tenth Street on the South Side to Second Avenue and the Armstrong Tunnel under the Bluff. A staircase leads from the northern terminus of the bridge up to the campus of Duquesne University on the Bluff.

In 2015, the bridge was one of three bridges to have bike specific lanes installed. It was listed on the National Register of Historic Places in 1986.
