Summit Bridge
The Summit Bridge carries Delaware Routes 71 and 896 across the Chesapeake & Delaware Canal. The bridge also carries Delaware Bicycle Route 1, a bicycle route that spans the length of the state of Delaware, across the canal. The Summit Bridge opened to traffic on January 9, 1960, replacing a lift bridge. Before the bridge opened to traffic, a dedication ceremony was held, with U.S. Senator J. Allen Frear Jr. in attendance. The Summit Bridge was the second four-lane high-level crossing in Delaware and was designed to carry an eventual US 301 freeway, however that planned freeway was never built on the alignment utilizing the Summit Bridge. US 301 did use the bridge when it was routed along surface roads from 1961 to 2019, at which time it was rerouted onto a new toll freeway. The current bridge replaces a former swing span structure that was demolished when the U.S. Army Corps of Engineers rerouted the canal to a new sea-level channel south of Lums Pond State Park Lums Pond St ...

Chesapeake & Delaware Canal
The Chesapeake & Delaware Canal (C&D Canal) is a -long, -wide and -deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States. In the mid‑17th century, mapmaker Augustine Herman observed that these great bodies of water were separated only by a narrow strip of land. In 1764, a survey of possible water routes across the Delmarva Peninsula was made, but little action followed. The idea was raised again in 1788 by regional business leaders, including noted Philadelphians Benjamin Franklin and Benjamin Rush. Despite the beginnings of a commercial venture in 1802—coincident with Canal Mania in England and Wales—it wasn't until 1829 before the C&D Canal Company could, at last, announce the waterway "open for business". Its construction cost of $3.5 million (equivalent to $ million in ) made it one of the most expensive canal projects of its time. In the present era, the C&D Canal is owned and operat ...

Chesapeake City Bridge
The Chesapeake City Bridge carries Maryland Route 213 across the Chesapeake & Delaware Canal in Chesapeake City, Maryland. There are two undivided traffic lanes and one sidewalk on the east side of the bridge. The U.S. Army Corps of Engineers began construction on the bridge in 1948 and it was opened to traffic in 1949. An older vertical lift drawbridge was destroyed on July 28, 1942, after being struck by the tanker '' Franz Klasen''. The bridge is identical in appearance to the old St. Georges Bridge in Delaware (they were constructed roughly at the same time) except for the number of lanes. Vertical lift span The Chesapeake City vertical lift span was constructed between 1924 and 1928. The bridge carried U.S. Route 213, connecting George Street on the south side of the canal with Lock Street on the north. Following the destruction of the bridge, the new high-level bridge was constructed approximately to the west. U.S. Route 213 was diverted to the new bridge, while t ...

Bridges Of The United States Numbered Highway System
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.

Road Bridges In Delaware
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 ...

Chesapeake & Delaware Canal Lift Bridge
The Chesapeake & Delaware Canal Lift Bridge is a railroad bridge with vertical-lift span in the U.S. state of Delaware. It carries a Delmarva Central Railroad rail line across the Chesapeake & Delaware Canal. This bridge was built by the U.S. Army Corps of Engineers as part of a canal expansion project and opened in 1966. The Canal Lift Bridge, the only drawbridge on the C & D Canal (other lift bridges, carrying vehicular traffic, had since been replaced with high-level crossings) was owned and operated by the Pennsylvania Railroad, Penn Central, and Conrail before Norfolk Southern acquired ownership of it in 1998 and the Delmarva Central Railroad took over in 2016. The bridge is used primarily by Delmarva Central Railroad on its Delmarva Subdivision, which has a junction with Norfolk Southern north of the bridge in Porter. Norfolk Southern trains use the bridge via trackage rights to interchange with the Delmarva Central Railroad in Clayton. It has also been used by Amtrak ...

Ellipse Sign 896
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. It generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity e, a number ranging from e = 0 (the limiting case of a circle) to e = 1 (the limiting case of infinite elongation, no longer an ellipse but a parabola). An ellipse has a simple algebraic solution for its area, but only approximations for its perimeter (also known as circumference), for which integration is required to obtain an exact solution. Analytically, the equation of a standard ellipse centered at the origin with width 2a and height 2b is: : \frac+\frac = 1 . Assuming a \ge b, the foci are (\pm c, 0) for c = \sqrt. The standard parametric equation is: : (x,y) = (a\cos(t),b\sin(t)) \quad \text \quad 0\leq t\leq 2\pi. Ellipses ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lums Pond State Park
Lums Pond State Park is a Delaware state park near Bear, New Castle County, Delaware in the United States. The park surrounds Lums Pond, an impoundment built by the Chesapeake and Delaware Canal on St. Georges Creek. The C&D built the pond as a source of water to fill the locks of the canal that connected the Chesapeake Bay with the Delaware River during the early 19th century. Lums Pond State Park is open for a wide variety of year-round recreation. History Lums Pond, the largest freshwater pond in Delaware, covering in central New Castle County, was built in the early 19th century as an impoundment for the Chesapeake and Delaware Canal. The pond supplied water to fill the locks of the canal and water power for a local gristmill. The pond became a natural recreational draw for the residents of Delaware. Ownership was transferred to the state of Delaware in the mid-20th century. Lums Pond State Park was opened to the public in 1963. The Lum's Mill House was added to the Natio ...
