List Of 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, 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] |

Frick Park
Frick Park is the largest municipal park in Pittsburgh, Pennsylvania, United States, covering . It is one of Pittsburgh's four historic large parks. History The park began when Henry Clay Frick, upon his death in 1919, bequeathed south of Clayton, his Point Breeze mansion (which is now part of the Frick Art & Historical Center). He also arranged for a $2 million trust fund ($ million today) for long-term maintenance for the park, which opened on June 25, 1927. He did this against his will, but rather acquiesced to his daughter Helen's debutante wish which he had promised to honor. Henry Clay Frick's son, Childs Frick, developed his lifelong love of animals in the woods and ravines of the park. Childs Frick went on to be a renowned American vertebrate paleontologist, major benefactor and trustee of the American Museum of Natural History. Over the years, the park grew from the original land in Point Breeze and now includes Squirrel Hill to the border of Edgewood. In a city th ...

Liberty Tunnel
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. Design The tunnels were designed by Amos D. Neeld, who would also supervise the construction of the adjoining Liberty Bridge, which gives travelers a way to cross the Monongahela River after passing through the tunnels. The design was two vertical wall horseshoe profile tunnels, each consisting of two lanes of traffic and a sidewalk. The sidewalks, being minimally used and in disrepair, were removed during a renovation in the 1970s in order to w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Panhandle 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
