Forbes Avenue is one of the longest streets inPittsburgh,Pennsylvania, United States. It runs along an east–west route for a length of approximately 7 mi (11 km).

According to historical writer and blogger Leon J. Pollom, the lowest section of Forbes Avenue was originally named Diamond Street. The remainder was named Forbes Street in honor ofJohn Forbes (1707–1759),^[1] whose expedition recapturedFort Duquesne and who renamed the place Pittsburgh in 1758. In 1958 during the administration of MayorDavid L. Lawrence, Diamond Street and Forbes Street were renamed and combined as Forbes Avenue.

In the past, a portion of what is now Forbes Avenue carried U.S. Routes 22 and30.^[2][3]

At approximately 6:45 AMEST on January 28, 2022, theFern Hollow Bridge carrying Forbes Avenue over Fern Hollow Creek in Frick Park collapsed, injuring ten; the bridge was just west of the intersection with Briarcliff Road. Six vehicles were left trapped in the rubble, including aPort Authorityarticulated bus.^[4] The three-span steelrigid-frame bridge, completed in 1973, was 446.9 ft (136.2 m) long and had been listed by theNational Bridge Inventory as being in poor condition since September 2011.^[5]

The collapse ruptured a 16 inch (41 cm)natural gas pipeline under the bridge, causing a "massive" leak that was isolated quickly byPeoples Natural Gas.^[4]

The buildings that stand along Forbes Avenue are a mixture of old and new. The westernmost terminus of Forbes Avenue lies atStanwix Street in thedowntown part of the city. This runs eastward past the recentPPG Place, directly throughMarket Square and then between the 19th centuryCourthouse and the 20th centuryCity-County Building.Duquesne University, though established in the 19th century, mostly abuts Forbes with some early- to mid-20th century buildings. Some mostly late-19th century buildings form Forbes's passage throughMidtown and theUptown. InOakland, it goes through a mixture of late 19th century stores, and then passes theUniversity of Pittsburgh'sCathedral of Learning (early 20th century) and the late 19th centuryCarnegie Library of Pittsburgh. From Oakland, Forbes Avenue continues eastward past 20th- and 21st- centuryCarnegie Mellon University and late 19th centurySchenley Park, through the small stores ofSquirrel Hill, and pastHomewood Cemetery andFrick Park before it reaches its eastern terminus at the site of the January 2022Fern Hollow Bridge collapse.
