Liberty Bridge (Pittsburgh)

The Panhandle Bridge (officially the Monongahela River Bridge) carries two rail lines of the Port Authority "T" line across the Monongahela River in Pittsburgh, Pennsylvania. The name comes from Pennsylvania Railroad subsidiary Pittsburgh, Cincinnati, Chicago and St. Louis Railroad, also known as the Panhandle Route, which operated over the bridge. The basic structure was built in 1903, and was the third railroad bridge on the site since 1863. It was raised in 1912-14 as part of a grade separation project. The bridge's function was to carry Panhandle Route passenger, mail and express trains from Pennsylvania Station in Pittsburgh, with a tunnel in between the station and the bridge. Pennsy Panhandle freight trains utilized the Ohio Connecting Bridge slightly downstream on the Ohio River, or went the long way around the West Virginia Panhandle via Conway, Pennsylvania. Rail traffic over the Panhandle Bridge declined as passenger trains were discontinued, and Amtrak became the only regular user of the bridge from 1971 to 1979, when the New York-St. Louis-Kansas City National Limited was discontinued on October 1 of that year. As PRR successor Conrail had no use for the bridge and the restrictive downtown tunnel, it was sold to the Port Authority, who rebuilt the bridge beginning in 1982 as part of the downtown light rail subway project, which removed trolleys from downtown streets and the Smithfield Street Bridge. PAT (as the Port Authority system was known at the time) light rail cars began using the bridge on July 7, 1985.

The Pittsburgh Terminal Properties building is an historic structure on Pittsburgh’s South Side, across the river from Downtown.

The Braddock expedition, also called Braddock's campaign or (more commonly) Braddock's Defeat, a failed British military expedition, attempted to capture the French Fort Duquesne (established in 1754, located in what is now downtown Pittsburgh) in the summer of 1755, during the French and Indian War of 1754 to 1763. The British troops suffered defeat at the Battle of the Monongahela on July 9, 1755, and the survivors retreated. The expedition takes its name from General Edward Braddock (1695–1755), who led the British forces and died in the effort. Braddock's defeat was a major setback for the British in the early stages of the war with France; John Mack Faragher characterises it as one of the most disastrous defeats for the British in the 18th century.

Grant Street Station, also known as the B&O Pittsburgh Terminal, was a passenger rail station on Grant Street downtown Pittsburgh, Pennsylvania. The Baltimore and Ohio Railroad (B&O) announced plans for it on May 3, 1955, after selling the original B&O Station bordering the Monongahela River to the state for construction of Interstate 376. It opened in 1957 to serve commuter rail traffic; all intercity traffic continued to use the Pittsburgh and Lake Erie Railroad's (P&LE) station (now called Station Square). Grant Street was the last such privately owned train station built in Pennsylvania.After the Port Authority of Allegheny County (PAT) assumed control of the B&O's Pittsburgh—McKeesport—Versailles commuter route in 1975 (which it re-branded PATrain), Grant Street continued to serve as the Pittsburgh depot for this service. PAT discontinued the service in 1989; Grant Street itself was demolished in 1998. The site is now home to PNC Firstside Complex and the First Avenue light rail station.

The Liberty Tunnels (also known as the Liberty Tubes) are a pair of tunnels located in Pittsburgh, Pennsylvania, United States that allow motorists to travel between the South Hills of Pittsburgh and the city, beneath Mt. Washington. The tunnels were vital in the expansion of the South Hills suburbs by providing a direct route to the city, eliminating the time-consuming task of navigating around or over Mt. Washington and its inclines. Opening in 1924, the Liberty Tunnels are the longest automobile tunnel in the City of Pittsburgh.

First Avenue is a station on Pittsburgh Regional Transit's light rail network. The station is part of the light rail's Downtown Pittsburgh free zone, and passengers embarking here may travel for free to any of the other stations within the zone (Steel Plaza, Wood Street, Gateway, North Side and Allegheny). The station was a new addition to the light rail system in 2001, located in the PNC Firstside Complex, just before the tracks dip into the subway tunnel. It was opened on November 16, 2001 to provide better access to the southern quarter of downtown, which includes city and state government offices, major office buildings such as Oxford Centre and the Grant Building, downtown educational facilities such as Point Park University, Duquesne University and the Art Institute of Pittsburgh, and the many smaller office structures that mark this area of the Golden Triangle. It cost $6.7 million to construct.

The Grant Building is 40-story, 147.8 m (485 ft) skyscraper at 310 Grant Street in downtown Pittsburgh, Pennsylvania. The building was completed and opened on February 1, 1929 at a cost of $5.5 million ($86.8 million today). The Art Deco building's facade is built with Belgian granite, limestone, and brick. It was famous for a radio antenna that rose roughly 100–150 feet (30–46 m) from the roof of the tower and had an aviation beacon that spelled out .--. .. - - ... -... ..- .-. --. .... or P-I-T-T-S-B-U-R-G-H in Morse Code. The beacon could be seen as far away as 150 miles (240 km) on clear nights. A smaller version of the beacon, still flashing out the name of the city remains to this day, although malfunctions with the relay switch caused it to spell "P-I-T-E-T-S-B-K-R-R-H", and eventually "T-P-E-B-T-S-A-U-R-G-H" before being repaired on July 27, 2009.The tower on the roof also served as the broadcast antenna for radio station KDKA Pittsburgh which made the first commercially licensed radio broadcast on election night of 1920. At 7:00 AM on its 14th birthday (February 2, 1934), the radio station inaugurated new studios on the Grant Building's third floor. Huntington National Bank, which operates a branch inside the tower, owns the signage rights, giving them two signs in the Pittsburgh skyline alongside Centre City Tower where Huntington has their Western Pennsylvania headquarters.

Duquesne University of the Holy Spirit ( or ; Duquesne University or Duquesne) is a private research university in Pittsburgh, Pennsylvania. Founded by members of the Congregation of the Holy Spirit, Duquesne first opened as the Pittsburgh Catholic College of the Holy Ghost in October 1878 with an enrollment of 40 students and a faculty of six. In 1911, the college became the first Catholic university-level institution in Pennsylvania. It is the only Spiritan institution of higher education in the world. It is named for an 18th-century governor of New France, Michel-Ange Duquesne de Menneville. Duquesne has since expanded to over 9,300 graduate and undergraduate students within a self-contained 49-acre (19.8 ha) hilltop campus in Pittsburgh's Bluff neighborhood. The school maintains an associate campus in Rome and encompasses ten schools of study. The university hosts international students from more than 80 countries although most students—about 80%—are from Pennsylvania or the surrounding region. Duquesne is classified among "R2: Doctoral Universities – High research activity". There are more than 93,000 living alumni of the university including two cardinals and the current bishop of Pittsburgh. The Duquesne Dukes compete in NCAA Division I. Duquesne men's basketball appeared twice in national championship games in the 1950s and won the NIT championship in 1955.
