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.
[6] The two cables, each 13 inches (33 cm) in diameter, are anchored in concrete vaults at either end of the span and travel over two 160-foot (49 m) towers resting on stone piers.
After construction of the piers and 116-foot (35 m) towers, workers on suspended catwalks began spinning the two 13-inch (33 cm) diameter steel cables in February, 1932.
McArdle Roadway, was completed in September, 1933, providing a highway connection from the south end of the bridge to the Liberty Tunnel and Mount Washington.
[2] A $1.8 million rehabilitation project was completed in 1978–79, including structural repairs, deck and sidewalk replacement, painting, and removal of the streetcar tracks.
This project included replacement of the deck, sidewalks, and lighting, structural repairs, painting, waterproofing, and installation of a novel system to dehumidify the bridge cables.
[3][27] The Tenth Street Bridge is known locally for its painted figures of four geese (sometimes described as dinosaurs or "dino-geese") at the top of the south tower, described as "quirky icons" by the Pittsburgh Tribune-Review.
Originally an unsanctioned work of street art created in the 1990s,[28] the geese were painted over when the bridge was repainted in 2018.
The original artist, Tim Kaulen, launched a petition to restore the geese which gathered enough signatures to win approval from the Allegheny County Council.
