St. Georges Bridge (Delaware)
The St. Georges Bridge is a steel tied arch bridge that carries U.S. Route 13 (US 13) across the Chesapeake & Delaware Canal in St. Georges, Delaware. Built by the U.S. Army Corps of Engineers and opened in 1942 as a high-level crossing, the bridge was the first four-lane, high-level crossing to span the canal. It replaced a previous vertical lift bridge which was damaged when a German merchant ship collided with it. History and near replacement On January 10, 1939, the ''S.S. Waukegan'' struck and destroyed the original St. Georges Bridge, killing the bridge tender. The replacement steel tied arch bridge over the canal opened on January 31, 1942. This bridge was the first four-lane crossing of the Chesapeake and Delaware Canal. Prior to the opening of the paralleling Delaware Route 1 turnpike and the Chesapeake & Delaware Canal Bridge in 1995 (since renamed the Senator William V. Roth Jr. Bridge), the bridge was the main north–south crossing in Delaware, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

US 13
U.S. Route 13 (US 13) is a north–south U.S. highway established in 1926 that runs for from Interstate 95 (I-95) just north of Fayetteville, North Carolina to US 1 in the northeastern suburbs of Philadelphia, Pennsylvania, in Morrisville. In all, it traverses five states in the Atlantic coastal plain region. It follows the Atlantic coast more closely than does the main north–south U.S. highway of the region, US 1. Due to this, its number is out of place on the general U.S. Route numbering grid, as it should be running east of US 15 but does not. Its routing is largely rural, the notable exceptions being the Hampton Roads area in Virginia and the northern end of the highway in Delaware and Pennsylvania. It is also notable for being the main thoroughfare for the Delmarva Peninsula and carrying the Chesapeake Bay Bridge–Tunnel to it in Virginia. US 13's original plan in 1926 had the route serve no further south than the Delmarva Peninsula. However, it has been extended ...

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 ...

Reedy Point Bridge
The Reedy Point Bridge carries Delaware Route 9 across the Chesapeake & Delaware Canal in Delaware City, Delaware, USA. A two-lane cantilever bridge similar in appearance to the Platt Bridge in Southwest Philadelphia (near Philadelphia International Airport), the Reedy Point Bridge was built by the U.S. Army Corps of Engineers and opened in 1968, replacing a lift bridge that crossed the C&D Canal prior to the 1955 widening project. Unlike the nearby St. Georges Bridge, the Reedy Point Bridge spans over salt marshes at the southern approach (which subjects Delaware Route 9 to periodic tidal flooding Tidal flooding, also known as sunny day flooding or nuisance flooding, is the temporary inundation of low-lying areas, especially streets, during exceptionally high tide events, such as at full and new moons.

Biddles Corner, Delaware
Biddles Corner is a location in St. George's Hundred, New Castle County, Delaware, United States. Biddles Corner is at the intersection of U.S. Route 13 and Port Penn Road just east of the Biddles Corner toll plaza on the Delaware Route 1 toll road south of the Chesapeake and Delaware Canal. History 1700s to 1850 The Vandergrift-Biddle House was built at Biddles Corner starting in the 18th century. The original property, consisting of 179 acres, was granted to Leonard Vandegrift by Thomas and William Penn in 1708 and became the Biddles Corner farm. The Vandergrift-Biddle House was listed on the National Register of Historic Places in 1978. The Retirement Barn, a historically important barn, was built in the Biddles Corner area between 1790 and 1810. The barn "is the last known surviving example in southern New Castle County of a tri-partite (three bay) traditional English style barn. Common in the 18th century this barn type was replaced with other modern agricultural buildin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tied Arch Bridge
A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends. Description Thrusts downwards on a tied-arch bridge deck are translated, as tension, by vertical ties between the deck and the arch, tending to flatten it and thereby to push its tips outward into the abutments, like for other arch bridges. However, in a tied-arch or bowstring bridge, these movements are restrained not by the abutments but by the strengthened chord, which ties these tips together, taking the thrusts as tension, rather like the string of a bow that is being flattened. Therefore, the design is also called a bowstring-arch or bowstring-girder bridge. The elimination o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
