The Hot Metal Bridge is a truss bridge in Pittsburgh, Pennsylvania that crosses the Monongahela River. The bridge consists of two parallel spans on a single set of piers: the former Monongahela Connecting Railroad Bridge, built in 1887, on the upstream side and the former Hot Metal Bridge, built in 1900, on the downstream side. The Monongahela Connecting Railroad Bridge carried conventional railroad traffic, while the Hot Metal Bridge connected parts of the J&L Steel mill, carrying crucibles of molten steel from the blast furnaces to the rolling mills on the opposite bank. During World War II 15% of America's steel making capacity crossed over the Hot Metal Bridge, up to 180 tons per hour. The upstream span was converted to road use after a 14.6 million restoration, and opened with a Mayor Murphy ceremony honoring former steel workers on June 23, 2000. The bridge connects 2nd Avenue at the Pittsburgh Technology Center in South Oakland with Hot Metal Street (South 29th Street) in the South Side. The downstream span reopened for pedestrian and bicycle use in late 2007 after two years of work.
The Pittsburgh History and Landmarks Foundation was responsible for managing the decorative lighting project for the bridge, which was lit with energy-efficient light-emitting diode (LED) and optical fiber technology on June 12, 2008.
The Hot Metal Bridge is the namesake of the defunct Hot Metal Grille at the nearby SouthSide Works shopping center; the online magazine of the University of Pittsburgh, HotMetalBridge.org; and other local entities.
