Clarks Ferry Bridge
The Clarks Ferry Bridge is a plate girder bridge that carries U.S. Routes 22 and 322 across the Susquehanna River near Duncannon, Pennsylvania, about 20 miles north of Harrisburg, Pennsylvania. It is a 4 lane expressway standard bridge. The bridge also provides safe passage for hikers, bikers, and pedestrians using the Appalachian Trail and BicyclePA Route J. It was completed in November 1986 replacing a 1925 concrete arch toll bridge. History The bridge's name is derived from John Clark, a Scottish settler who in 1788 operated a ferry across the river and the next year established a tavern on the West Shore to cater to riders. After John and his oldest son Daniel both passed away in 1800, youngest son Robert inherited and continued to successfully operate the ferry and tavern. It became such a large draw to travelers that the Commonwealth of Pennsylvania decided by the mid 1820's that a permanent bridge should be established. An earliest covered bridge was at this site, buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Trail
The Appalachian Trail (also called the A.T.), is a hiking trail in the Eastern United States, extending almost between Springer Mountain in Georgia and Mount Katahdin in Maine, and passing through 14 states.Gailey, Chris (2006)"Appalachian Trail FAQs" Outdoors.org (accessed September 14, 2006) The Appalachian Trail Conservancy claims the Appalachian Trail to be the longest hiking-only trail in the world. More than three million people hike segments of the trail each year. The trail was first proposed in 1921 and completed in 1937 after more than a decade of work. Improvements and changes have continued since then. It became the Appalachian National Scenic Trail under the National Trails System Act of 1968. The trail is maintained by 31 trail clubs and multiple partnerships, and managed by the National Park Service, United States Forest Service, and the nonprofit Appalachian Trail Conservancy. Most of the trail is in forest or wild lands, although some portions traverse towns, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Canal
The Pennsylvania Canal (or sometimes Pennsylvania Canal system) was a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts. The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items.The political push to create the system was inspired by competition with New York and Baltimore, all three vying to be the premier major port city, and in particular, the continuing construction of the Erie Canal, begun in 1817. The news that construction of the Erie was expected on schedule, in 1825 added fuel to what had become a frenzy. The Erie began operations on October 26, 1825, further inspiring Pennsylvanians to over achieve in the Great Works projects. Portaging over the Alleghenies by 1834 was one result, though the Delaware Canal project was delayed to fund the western infrastructure connecting Allegheny County to the Center and Easte ...

Former Toll Bridges In Pennsylvania
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the a ...

Road Bridges In Pennsylvania
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", which ...

Bridges Completed In 1986
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 wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marysville Bridge
The Marysville Bridge was a covered bridge railroad crossing of the Susquehanna River between Marysville, Pennsylvania and Dauphin, Pennsylvania. It was built in 1858 and demolished in 1903. Several of its piers still remain in the river; one of them bears a small-scale replica of the Statue of Liberty. Marysville Bridge As the Northern Central Railway built north up the Susquehanna River from Baltimore, Maryland to the coal regions, it had to cross from the west to the east bank of the Susquehanna. The chosen crossing site was at the Dauphin Narrows, between Marysville on the west and Dauphin on the east. The bridge was finished in 1858, allowing the Northern Central to haul coal from Sunbury, Pennsylvania to Baltimore. However, the construction of a line from Dauphin to Rockville and the takeover of the Northern Central by the Pennsylvania Railroad in 1875 resulted in most Northern Central traffic being rerouted over the PRR's Rockville Bridge a short distance downstream.

Trevorton Bridge
The Trevorton Bridge was an uncovered wooden truss bridge that crossed the Susquehanna River. It was erected between Herndon in Northumberland County and Port Trevorton in Snyder County, Pennsylvania. The bridge was long, with a trestle crossing White Island in the middle of the river. It was originally built in 1854 as a railroad bridge by the Susquehanna & Union Bridge Co., later a subsidiary of the Trevorton and Susquehanna Railroad and, in September 1855, the bridge was adapted for use as a road bridge as well as for trains. The bridge was most often used to cross the Susquehanna by cattle. The continuous crossing of cattle endangered the already weakened bridge (weakened from acid in the bark the pine used to construct the bridge). The bridge was eventually dismantled in 1870 for fear that it would collapse.

List Of Crossings Of The Susquehanna River
List of Susquehanna River crossings proceeding upstream from the river mouth at the Chesapeake Bay in Maryland, United States, generally northward through Pennsylvania toward the main branch headwaters in New York. The West Branch crossings are listed afterward. This list includes active road, railroad, foot, and trail bridges, dams, fords, ferries, and historic crossings. Presently it does not include historic ferry crossings. Railroad lines are generally as shown on the USGS topographic maps, which may not have been updated to reflect the creation of Conrail in the 1970s, which absorbed many lines in this area. Main Branch Main Branch crossings are listed from the mouth of the river in the Chesapeake Bay up to the source at Otsego Lake in Cooperstown, New York. In a geological sense, the Chesapeake Bay is just the ria, submerged valley, of the Susquehanna River. In that sense the Chesapeake Bay Bridge Tunnel and the Chesapeake Bay Bridge crossings precede those in the conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
