Spring Garden Street Bridge
Spring Garden Street Bridge is a highway bridge in Philadelphia, Pennsylvania. It crosses the Schuylkill River below Fairmount Dam and connects West Philadelphia to the Philadelphia Museum of Art and Benjamin Franklin Parkway. It is the fourth bridge at this location. The bridge is located at . 1st bridge: The Colossus As early as 1693, a ferry operated, crossing the Schuylkill River at Fairmount, the hill on which the Philadelphia Museum of Art now stands. Being upstream of the others, this was called the Upper Ferry. For the Upper Ferry site, bridgebuilder Louis Wernwag designed "The Colossus", the longest single-span wooden bridge in the United States. Construction began in April 1812, and it opened on January 7, 1813. A double-arched-truss with a clear span of , it was a marvel of engineering for its time. Also called the "Colossus of Fairmount," the "Upper Ferry Bridge," and the "Lancaster Schuylkill Bridge," the toll bridge was part of the Philadelphia and Lancaste ...

Philadelphia
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Wheeling Suspension Bridge
The Wheeling Suspension Bridge is a suspension bridge spanning the main channel of the Ohio River at Wheeling, West Virginia. It was the largest suspension bridge in the world from 1849 until 1851. Charles Ellet Jr. (who also worked on the Niagara Falls Suspension Bridge) designed it and supervised construction of what became the first bridge to span a major river west of the Appalachian mountains. It linked the eastern and western section of the National Road, and became especially strategically important during the American Civil War. Litigation in the United States Supreme Court concerning its obstruction of the new high steamboat smokestacks eventually cleared the way for other bridges, especially needed by expanding railroads. Because this bridge was designed during the horse-and-buggy era, 2-ton weight limits and vehicle separation requirements applied in later years until it was closed to automobile traffic in September 2019. The main span is from tower to tower. The eas ...

Kayak
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word ''qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and "fli ...

Schuylkill River Trail
The Schuylkill River Trail ( , ) is a multi-use trail along the banks of the Schuylkill River in southeastern Pennsylvania. Partially complete as of 2018, the trail is ultimately planned to run about from the river's headwaters in Schuylkill County to Fort Mifflin in Philadelphia. Completed portions of the trail include a section from Auburn to Hamburg, a portion from Reading to Pottstown, and a portion from Oaks to South Street in Center City Philadelphia. Large stretches of the trail are rail trails. Parts of it belong to the East Coast Greenway, a 3,000-mile trail system connecting Maine to Florida. On many maps and street atlases, and on some of the trail's signage, the segment between Philadelphia and Valley Forge is still identified by the older name ''Philadelphia–Valley Forge Trail''. Trail description Auburn to Pottstown The Schuylkill River Trail begins at a trailhead at the Kernsville Dam in Auburn just above Hamburg. The trail runs through Reading to Po ...

Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name The Pennsylvania Railroad Company also known as the "Pennsy", was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, T ...

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

Bridge
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 ...
