The Donora–Monessen Bridge, officially known as the Stan Musial Bridge, is a truss bridge that carries vehicles across the Monongahela River between Donora and Monessen in Pennsylvania, U.S.A. The bridge was built in 1972, as part of a 1960s-era project to increase access to the industrial Monongahela Valley through a semi-freeway connection to Interstate 70. However, the decline of the steel sector halted area road construction, and the entire project was not completed until 1989. The road was originally named for former State Engineer C. Vance DeiCas.
