Emlenton Bridge
The Emlenton Bridge is a steel-deck truss bridge that spans the Allegheny River just south of the town of Emlenton, Pennsylvania, United States at approximately mile marker 44.4 on I-80. With a height of above the river, the Emlenton Bridge was the highest bridge in the Interstate Highway System when completed in 1968 (The Lewiston-Queenston Bridge is higher but is technically an international bridge, not part of the Interstate Highway system). This record was held until 1971 with the opening of the Fred G. Redmon Bridge near Selah, Washington. The Emlenton Bridge remains the highest road bridge in Pennsylvania; with an overall span of it was the largest bridge constructed as part of the Keystone Shortway project. With the completion of the Interstate System, it is likely that the Emlenton Bridge will remain the fifth-highest bridge in the system for a significant time, behind the Glade Creek Bridge in West Virginia, the Pine Valley Creek Bridge in California, the Galena C ...

Interstate 80 In Pennsylvania
Interstate 80 (I-80) in the US state of Pennsylvania runs for across the northern part of the state. It is designated as the Keystone Shortway and officially as the Z.H. Confair Memorial Highway. This route was built mainly along a completely new alignment, not paralleling any earlier US Routes, as a shortcut to the tolled Pennsylvania Turnpike to the south and New York State Thruway to the north. It does not serve any major cities in Pennsylvania and serves mainly as a cross-state route on the Ohio–New York City corridor. Most of I-80's path across the state goes through hilly and mountainous terrain, while the route passes through relatively flat areas toward the western part of the state. I-80 serves many smaller cities in central to northern Pennsylvania including Sharon, Clarion, DuBois, Bellefonte, Lock Haven, Milton, Bloomsburg, Hazleton, and Stroudsburg. It also passes close but never into four slightly larger cities: Williamsport, State College, Scrant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galena Creek Bridge
The Galena Creek Bridge is a twin-span concrete arch bridge in Washoe County, Nevada. The bridge carries Interstate 580 and U.S. Route 395 over the Galena Creek between Carson City and Reno. It was opened to traffic in late August 2012. The bridge has a total length of and main span length of . The height is . The bridge is reportedly the largest cathedral arch bridge in the world; that is a type of open-spandrel deck arch bridge where the arch supports the deck only at the center. Construction was started in 2003 but was delayed by a number of safety concerns and other issues. In 2006, the original prime contractor found the planned construction method unsafe; the method was revised and a new contractor hired. In 2010, several long superficial cracks were found. On July 28, 2012, the Nevada Department of Transportation held a community event for pedestrian, bicycle, and limited motor vehicle traffic to see the bridge prior to it opening for traffic; the bridge and freeway ...

Bridges Over The Allegheny River
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] |
Foxburg Bridge (2008)
The Foxburg Bridge carries PA 58 over the Allegheny River between Armstrong County, Pennsylvania and Clarion County, Pennsylvania in Foxburg, Pennsylvania, USA. History The new bridge was completed alongside the old Foxburg Bridge which was demolished to allow the pedestrian walkway to be added. The project began in 2007 and was due to end in 2009 but the bridge opened to traffic ahead of schedule. The cost of the project was $10.1 million.

PA-38
The Piper PA-38-112 Tomahawk is a two-seat, fixed tricycle gear general aviation airplane, originally designed for flight training, touring and personal use. Design and development The Tomahawk is a single-engined low-wing cantilever monoplane with a T-tail and an enclosed cabin for two. It has a fixed tricycle landing gear and is powered by a Lycoming O-235 four-cylinder piston engine with a twin-bladed tractor propeller. The Tomahawk has two front-hinged doors for access to the cabin. The Tomahawk was Piper Aircraft, Piper's attempt at creating an affordable two-place trainer. Before designing the aircraft, Piper widely surveyed flight instructors for their input into the design. Instructors requested a more Spin (flight), spinnable aircraft for training purposes, since other two-place trainers such as the Cessna 150 and Cessna 152, 152 were designed to spontaneously fly out of a spin. The Tomahawk's NASA GA(W)-1 Richard T. Whitcomb, Whitcomb airfoil addresses this requirement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emlenton Low Level Bridge
The Emlenton Low Level Bridge is a girder bridge that spans the Allegheny River at Emlenton in the U.S state of Pennsylvania. It connects two separate portions of the borough in Venango and Clarion counties. It replaced, an 1883 truss bridge that stood just upstream, which replaced several previous wooden structures; the modern bridge was constructed in 1987. This bridge is dwarfed by its more famous nearby cousin, the 1968 Emlenton Bridge along Interstate 80.

List Of Bridges In The United States By Height
This is a list of the highest bridges in the United States by height over land or water. ''Height'' in this list refers to the distance from the bridge deck to the lowest point on the land, or the water surface, directly below. A bridge's deck height is greater than its ''clearance below'', which is measured from the bottom of the deck structure, with the difference being equal to the thickness of the deck structure at the point with the greatest clearance below. Official figures for a bridge's height are often provided only for the clearance below, so those figures may be used instead of actual deck height measurements. For bridges that span tidal water, the clearance below is measured at the average high water level. The minimum height for inclusion in this list is ', which may be either the ''deck height'' or the ''clearance below'' depending on available references. Note that the following types of bridges are not included in this list: demolished high bridges; historic high b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
