Monongahela River Bridge
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Authority Of Allegheny County
Pittsburgh Regional Transit (PRT, formerly Port Authority of Allegheny County) is the second-largest public transit agency in Pennsylvania and the 20th-largest in the United States. The state-funded agency is based in Pittsburgh and is overseen by a CEO and a nine-member board of unpaid volunteer directors, five of whom are appointed by the county executive and approved by the county council; and one each by the majority and minority leaders by each political party. After operating as the Port Authority of Allegheny County for most of its history, the agency rebranded under its current name in June 2022. In , the system had a ridership of . Pittsburgh Regional Transit's bus, light rail and funicular system covers Allegheny County. On some longer-distance routes, service extends into neighboring counties such as Beaver, Washington, and Westmoreland. These counties have their own transit systems, including several routes that run into downtown Pittsburgh, where riders can mak ...

National Limited (Amtrak)
The ''National Limited'' was a passenger train that ran between Kansas City, Missouri, and both New York City and Washington, D.C., splitting in Pennsylvania. Amtrak operated the train from 1971 to 1979. History In 1970, the Department of Transportation, in its designation of endpoints for the Amtrak system, designated a train to run between New York, Washington and St. Louis. This was later amended to run all the way to Kansas City, with a connection to the ''Super Chief'' running between Chicago and Los Angeles. The route was being served, prior to Amtrak, by the '' Spirit of St. Louis'', originally run by the Pennsylvania Railroad and later inherited by Penn Central. Amtrak initially retained the ''Spirit of St. Louis'', extending it to Kansas City along the Missouri Pacific Railroad. In July 1971, the train was renamed the ''National Limited'' to better reflect the scope of the route. That name had been used by another New York-St. Louis train operated by the Baltimo ...

Bridges Completed In 1903
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges In 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, at the time, Pittsburgh had 446 bridges. With its proximity to three major rivers and countless hills and ravines, Pittsburgh is known as ''"The City of Bridges"''. History 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 centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberty Bridge (Pittsburgh)
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. History The Liberty Bridge is a steel cantilever bridge and was constructed as the missing link between downtown Pittsburgh and the Liberty Tunnel, which had been constructed four years earlier in 1924 as a link to the South Hills. The bridge opened on March 27, 1928, following a vehicle parade from the southern suburbs of the city, which crossed the Smithfield Street Bridge and proceeded through downtown before ending at the southern end of the new bridge. It was designed by George S. Richardson and cost $3,456,000 to build. It is 2663' 3/16" long, though the main span is 448' and the water clearance is 44.4'. It was renovated in 1982 by the Dick Corporation, at a cost of $32 million. Fire On September 2, 2016 the L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Authority Of Allegheny County T Line Logo
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...

Pittsburgh & Steubenville Extension Railroad Tunnel
The Pittsburgh & Steubenville Extension Railroad Tunnel, also known as the Panhandle Tunnel, was originally built for the Pittsburgh and Steubenville Extension Railroad in Pittsburgh. It officially opened for rail traffic in 1865. History The tunnel has been modified many times since it was first constructed. In the years after the construction the southern end was lengthened by to accommodate the overpass of Forbes Avenue. This new tunnel had a height of , lower than the main tunnel. The southern end was again extended around 1900 to add a sidewalk to the road. This extension lowered the height of the tunnel to the current . Light Rail The tunnel and the adjacent Panhandle Bridge were purchased by the Port Authority from Penn Central Corporation for $8.15 million in 1980. The tunnel is now utilized by the Pittsburgh Light Rail System for some of its right-of-way and the Steel Plaza Station.
