How Many Bridges Are in Pittsburgh?

Pittsburgh has approximately 446 bridges in total. This count includes vehicular bridges, pedestrian bridges, and rail bridges, making Pittsburgh the city with the most bridges in the world, even more than Venice.

Out of these, the City of Pittsburgh itself owns 143 active bridges spanning rivers, valleys, and various terrains within its limits. The rest are owned by entities like Allegheny County, Pennsylvania Department of Transportation (PennDOT), transit authorities, railroads, or private groups.

These bridges vary in design and purpose, with notable examples including the Fort Pitt Bridge and Fort Duquesne Bridge that are key to transportation infrastructure. The extensive number reflects Pittsburgh's unique geography, featuring three major rivers—the Allegheny, Monongahela, and Ohio—that require many crossings to connect neighborhoods.
