Bridges of Pittsburgh
The Bridges of Pittsburgh play an important role in the city's transportation system. Without bridges, the Pittsburgh region would be a series of fragmented valleys, hillsides, river plains, and isolated communities.
A 2006 study determined that Pittsburgh has 446 bridges, and with its proximity to three major rivers and countless hills and ravines, Pittsburgh is known as "The City of Bridges". The city of Pittsburgh and Allegheny County are the largest owners of great bridges in the country, in proper proportion to their size, with the possible exception of the City of New York, which is built on an island and surrounded by large bodies of water.
Pittsburgh's first river bridges, made of wood and long since replaced, opened in 1818 at Smithfield Street and 1819 at Sixth Street (then St. Clair Street). The city's oldest in-service bridge is the current Smithfield Street Bridge, which opened in 1883; it was designated a National Historic Landmark in 1976. Pittsburgh waged a massive road- and bridge-building campaign from 1924 to 1940; most of Pittsburgh's oldest major bridges date from this period. The coming of the Interstate Highway System triggered more construction in the second half of the twentieth century, as vehicular speed and throughput requirements increased. The result of more than 100 years of bridge building is a collection of most of the major types of bridge (suspension, cantilever, arch, etc.), mostly built from locally produced steel, including about forty river spans.
Many of the bridges in the Downtown area are colored Aztec Gold, either constructed as such or painted afterward, to match the city's official colors of black and gold. A few old and out-of-service bridges, such as the Hot Metal Bridge (which stood dormant until reopening as a passenger bridge in the year 2000), are exceptions to this rule.

- The Fort Pitt Bridge is a steel bowstring arch bridge that spans the Monongahela River near its confluence with the Allegheny River at the point. It carries Interstate 376 between the Fort Pitt Tunnel and Point State Park.
- The Fort Duquesne Bridge is a steel tied arch bridge that spans the Allegheny River in Pittsburgh, Pennsylvania. It carries Pennsylvania Route 65 / Interstate 279 (North Shore Expressway), which runs through Downtown Pittsburgh's Golden Triangle towards Interstate 79.
- The West End Bridge is a large steel arch bridge which crosses the Ohio River. It is the first bridge on the Ohio River heading toward the Mississippi River. The bridge carries U.S. Route 19.
- The Liberty Bridge crosses over the Monongahela River, intersecting Interstate 579 at its southern terminus.
- The Three Sisters are three parallel, nearly identical self-anchored suspension bridges that cross the Allegheny River at 6th, 7th, and 9th streets. The sisters have been recently renamed "The Three Siblings" (or Brobrosis), for prominent Pittsburgh residents: Roberto Clemente Bridge, Andy Warhol Bridge, and Rachel Carson Bridge.
- The Smithfield Street Bridge is a lenticular truss bridge crossing the Monongahela River. Its two main lenticular spans make the bridge very recognizable. It is a National Historic Civil Engineering Landmark, according to a plaque on the bridge.
