Pittsburgh has more bridges than any other city in the world.

The city with the most bridges in the world is right here in Pennsylvania: Pittsburgh. 

The Steel City boasts 446 bridges. Here are some of the most iconic, recognizable bridges to spot next time you’re in Pittsburgh.

Three Sisters Bridges

The most recognizable bridges in Pittsburgh are the Three Sisters Bridges. The three bridges are the only trio of identical bridges in the United States. 

The Three Sisters Bridges cross the Allegheny River and connect Downtown and the North Shore. 

Each bridge in the trio was named after a notable Pittsburgh resident. Roberto Clemente, Andy Warhol, and Rachel Carson are honored through the names of the 6th, 7th, and 9th Street Bridges. 

Fort Pitt Bridge

Travelers coming to Pittsburgh from the airport into downtown exit the Fort Pitt Tunnel and take the Fort Pitt Bridge. From the bridge, visitors are met with a captivating view of the city. 

The bridge crosses the Monongahela River near Point State Park. It is the world’s first computer-designed bowstring arch bridge and the first double-decker arch bridge. 

Smithfield Street Bridge

The Smithfield Street Bridge replaced Pittsburgh’s first bridge, the Monongahela Bridge, after it sustained damage. The bridge is the city’s longest in-service bridge, and stands in the spot where the Monongahela Bridge was the first one to cross the Monongahela River. 

The Smithfield Street Bridge is the oldest steel bridge in the United States and was designated a national historic landmark in 1976.

Erskine Covered Bridge

The Erskine Covered Bridge was built in 1845. It is the oldest bridge in Washington County and was designated a historic bridge by the Washington County History and Landmarks Foundation in 1979.

The bridge is the farthest west bridge in Pennsylvania, just one-tenth of a mile from West Virginia.

10th Street Bridge (Philip Murray Bridge)

The 10th Street Bridge has the longest span across the Monongahela River. Across the three rivers that run through the Steel City, it is the only cable suspension bridge. 

The bridge honors Philip Murray, the first president of the United Steelworkers of America. It honors the impact the labor movement had on the city. 

Washington’s Landing Bridge (Herr’s Island Railroad Bridge)

In 1753, George Washington’s raft capsized and he needed to stay on an island in the Pittsburgh region. The Washington Landing Bridge connects the Three Rivers Heritage Trail to Washington’s Landing, where he stayed, and is commonly used by bicyclists. 

Washington Crossing Bridge (40th Street Bridge)

Another bridge in Pittsburgh named for the first president, the Washington Crossing Bridge connects Lawrenceville to Millvale. It was named after young George Washington, who was nearly killed crossing the river when traveling south to the forks of Ohio.

The bridge is adorned with cast-iron seals of the original thirteen colonies of the United States.
