Masontown Bridge
The Masontown Bridge is a four-lane, concrete, plate girder bridge that carries vehicular traffic across the Monongahela River between Masontown, Pennsylvania and Monongahela Township, Pennsylvania (near Carmichaels), by way of Pennsylvania Route 21. History and notable features The current structure was completed and opened in December 2015 after a three-year project costing $49.6 million to replace the previous truss bridge that was built in 1925 and rehabilitated in 1993. The first two lanes of the new bridge were completed in 2013, at which point the old truss bridge was imploded to make way for the other two lanes of the new bridge. It cost $50 million to build the new bridge. The new bridge was constructed by Brayman Construction. The Pennsylvania Department of Transportation undertook the bridge replacement project as part of a years-long effort to modernize and improve Route 21 and expand it in some areas. The old bridge was one of many large truss bridges built in Pennsy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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", whic ...

Bridges In Greene County, Pennsylvania
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.

Grays Landing Lock & Dam
Grays Landing Lock and Dam, previously known as Lock and Dam Number 7, is one of nine navigational structures on the Monongahela River between Pittsburgh, Pennsylvania and Fairmont, West Virginia. Maintained and built by the U.S. Army Corps of Engineers, the gated dam forms an upstream pool that is long, stretching to the base of the Point Marion Lock and Dam. It is located at river mile 82. There is one lock chamber on the right descending bank of the river at the dam. The reservoir formed by the dam is also a municipal and industrial water supply.
