Millions of visitors comment that while Pittsburgh is the City of Bridges, it lacks a covered bridge. Most believe that the last covered bridge in the county was demolished in the 1920's. This, however, is no longer true. In 2010, BridgeMapper.com found the county's only remaining covered bridge, as pictured above! As such, it is Pennsylvania's most significant bridge.
