The Donora–Webster Bridge was a truss bridge spanning the Monongahela River between the borough of Donora, Pennsylvania and the village of Webster in Rostraver Township, Pennsylvania. Originally built in 1908 to serve rail traffic, the bridge was eventually fully converted in 1938 for automobile use only.. The structure connected Route 837 on the west bank of the river and Route 906 on the east side. The closest open crossings are at Route 1022 to the south (upstream), and the Route 136 to the north (downstream), a several-mile detour either way. As early as the 1960s, the bridge had been known to be functionally obsolete, resulting in construction of the Donora–Monessen Bridge. and on July 1, 2015, the bridge was demolished after being closed for several years due to severe structural deficiency.
