There's the Roberto Clemente Bridge at 6th Street, the Andy Warhol Bridge at 7th Street and the Rachel Carson Bridge at 9th Street.
The next bridge to be named is the 10th Street Bridge, which spans the Monongahela River from Uptown to the South Side. County Council is poised to call the span the Philip Murray Bridge.
He's not exactly a household name, but Philip Murray is key to the history of the region.
He was born in Scotland in 1886 and emigrated to the United States in 1902 where he worked as a coal miner in Westmoreland County. Two years later he joined the United Mine Workers of America and was elected president of his local the next year.
He remained active in the labor movement and was named the first chairman of the Steel Workers Organizing Committee when it was formed in 1936, then four years later he was elected president of the Congress of Industrial Organizations in 1940.
Mr. Murray became the first president of the United Steelworkers of America in 1942 when, after several significant steel strikes in which the Steel Workers Organizing Committee prevailed, it was disbanded to become the United Steelworkers.
"It's hard to imagine someone more deserving of having a Pittsburgh landmark named after him than Philip Murray," said United Steelworkers president Leo W. Gerard.
The legislation to change the name of the bridge was sponsored by County Councilman John DeFazio, D-Shaler, who also is the elected representative of the Steelworkers for the Pennsylvania district.
County Manager Jim Flynn said the county administration will work with Mr. DeFazio on an appropriate dedication, which will most likely take place on Labor Day.
Councilman Charles Martoni, D-Swissvale, who chairs the public works committee, supported the proposal.
"It would be good for us to get the word out about the contribution labor made to creating the middle class in this country," he said.
The legislation was moved through that committee last night and will be before the full council on May 1, which also is International Workers Day.
