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 Smithfield Street Bridge is a lenticular truss bridge crossing the Monongahela River in Pittsburgh, Pennsylvania, USA. The bridge was designed by Gustav Lindenthal, the engineer who later designed the Hell Gate Bridge in New York City. The Smithfield Street Bridge was built between 1881 and 1883, opening for traffic on March 19, 1883. It was widened in 1889 and widened again in 1911. The bridge has been designated a National Historic Civil Engineering Landmark, a National Historic Landmark, and has a Historic Landmark Plaque from the Pittsburgh History and Landmarks Foundation.

B&O Railroad Depot was one of several railroad stations in the city of Pittsburgh, Pennsylvania during the late 19th and early 20th century. The station was built in 1887, 16 years after the B&O Railroad opened its first railroad line into Pittsburgh. The station was built next to the Monongahela River. B&O railroad trains also used the Pittsburgh & Lake Erie Railroad Station for services that continued westward towards Chicago via the Pittsburgh & Lake Erie Railroad. In 1955 the station was demolished to make room for an interstate highway and remaining services were transferred to Grant Street Station. The building was designed by Frank Furness who also constructed the B&O Railroad's Philadelphia station.At the time of its 1955 closing, major named long distance passenger trains making stops at the station included: Ambassador Capitol Limited Columbian Cleveland Night Express Shenandoah Washington–Chicago Express WashingtonianAdditionally, the B&O operated a train from Pittsburgh to Buffalo via DuBois and East Salamanca.

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 Bridge, completed in 1928, connects downtown Pittsburgh, Pennsylvania, to the Liberty Tunnels and the South Hills neighborhoods beyond. It crosses the Monongahela River and intersects Interstate 579 (the Crosstown Boulevard) at its northern terminus.

The Hartley-Rose Belting Company Building in Pittsburgh, Pennsylvania, is a building from 1906. It was listed on the National Register of Historic Places in 1983.

Station Square is a transit station on Pittsburgh Regional Transit's light rail network. It is the last Transit station on the south side of the Monongahela River. This station is named for the nearby Station Square mixed-use development and opened in 1985. Many South Hills residents access the facility using light rail service, and employees at the adjacent major office park, which includes the headquarters of WESCO International are also major beneficiaries of the stop. Several thousand commuters each weekday also rely on this stop as a park-and-ride station, using either a 160 space Pittsburgh Regional Transit lot or the privately owned garage in Station Square. The station's close proximity to the Monongahela Incline, South Busway, Carson and Smithfield Streets, and the large parking facilities and boat docks of the Gateway Clipper Fleet at Station Square add to the station's inter-modal transportation value.

The Pittsburgh & Lake Erie Railroad Station, now Landry's, Inc.'s the Grand Concourse restaurant in Station Square Plaza in Pittsburgh, Pennsylvania, is a building constructed in 1898. Into the 1960s, the station was the depot for the passenger rail operations of the Pittsburgh & Lake Erie Railroad and the Pittsburgh depot from 1934 for the many trains of the Baltimore and Ohio Railroad from Baltimore, Washington, Chicago, Detroit, and St. Louis. In 1934, the B&O obtained trackage rights on the P&LE from New Castle Junction to McKeesport and, until the discontinuance of its passenger service, used the P&LE station to reduce the amount of heavy-curvature trackage required to reach the original B&O station on the opposite side of the Monongahela River.The Pittsburgh Station was listed on the National Register of Historic Places in 1974.

The Salvation Army Building is a historic building located at 425-435 Boulevard of the Allies in Pittsburgh, Pennsylvania.

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.

Pittsburgh and Castle Shannon Plane was a 3 ft 4 in (1,016 mm) narrow gauge incline railway that ran from the northern end of the Pittsburgh and Castle Shannon Tunnel to Carson Street in Pittsburgh, Pennsylvania. Originally built to carry coal from the Jacob Beltzhoover mine, it was sold by the Pittsburgh Coal Company to the Pittsburgh and Castle Shannon Railroad in 1871. It was used only for coal as early as 1864, passenger traffic was added in 1874 for the Pittsburgh and Castle Shannon Railroad. For safety reasons, the tunnel was closed to passenger traffic, and passengers were diverted to the Castle Shannon Incline, constructed in 1890. Emergency use of the plane for passengers and freight continued as late as 1900. Its use for the transport of passengers and freight other than coal was made obsolete by the Mount Washington Transit Tunnel. Operation as a coal incline continued until May 1, 1912. It was operated as a gravity plane, with returning empty cars being pulled to the mine mouth by the weight of the descending full coal cars.
