Hill To Hill Bridge
The Hill to Hill Bridge is a road crossing of the Lehigh River and linking the south and north sides of Bethlehem, Pennsylvania in the Lehigh Valley region of the United States. Completed in 1924, Hill to Hill Bridge carries Pennsylvania Route 378 from Wyandotte Street on Bethlehem's south side to a series of ramps and viaducts on the north side. It replaced a two-lane covered bridge and eliminated several grade crossings of three railroads on the two banks of the Lehigh River. The Hill to Hill Bridge is located in the Central Bethlehem Historic District and was added to the National Register of Historic Places in 1972 with a boundary increase to the designation added in 1988. History Early history Prior to Bethlehem's incorporation as a city in 1917, the north side and the south side were independent municipalities. During the latter part of the 1910s, three bridges crossed between Bethlehem and South Bethlehem: the Minsi Trail bridge, the New Street bridge, and the Main Stree ...

The river's name "Lehigh" is an anglicisation of the Lenape name for the river, ''Lechewuekink'', which means "where there are forks". Both Lehigh County and Lehigh Valley are named for the river. According to an environmental report from a Pennsylvania nonprofit research center, the Lehigh River watershed is ranked second nationally in the volume of toxic substances released into it in 2020.

Historic District Contributing Properties In Pennsylvania
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Bridges In Northampton 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. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concrete Bridges In Pennsylvania
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lehigh And New England Railroad
The Lehigh & New England Railroad was a Class I railroad located in Northeastern United States that acted as a bridge line. It was the second notable U.S. railroad to file for abandonment in its entirety, the first being the New York, Ontario & Western Railway. History South Mountain and Boston and successors: 1873-1882 Around 1868, serious proposals for the crossing of the Hudson River at Poughkeepsie began to appear. A charter for the Poughkeepsie Bridge Company was obtained in 1871, and the company was organized before the end of May. The charter was amended to allow placing piers in the river by 1872 (despite fierce opposition from navigation interests), and the company began raising funds. Through the influence of Andrew Carnegie, Pennsylvania Railroad president J. Edgar Thomson was persuaded to personally invest in the project. This funding led to a surge of activity. The line was to be carried from Harrisburg to the crossing of the Delaware River at Portland by the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
