Delaware Route 71
Delaware Route 71 (DE 71) is a state highway in New Castle County, Delaware. The route runs from U.S. Route 13 (US 13) south of Townsend north to another intersection with US 13 in Tybouts Corner, traveling to the west of US 13 by way of Townsend, Middletown, and the Summit Bridge. The route runs concurrent with DE 896 from Mount Pleasant to just north of the Summit Bridge. DE 71 was built as a state highway during the 1920s and 1930s. By 1938, the route was designated to run from US 13 south of Townsend north to US 13 in Tybouts Corner roughly along its present-day alignment. In the 1950s, DE 71 was rerouted to head to the Maryland border southwest of Middletown to connect to Maryland Route 71 (MD 71), with the former route south of Middletown becoming an extended DE 896. Between the 1950s and 1980s, DE 71 was signed with various alignments of US 301 and US 301S. In the 1980s, DE 7 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware Department Of Transportation
The Delaware Department of Transportation (DelDOT) is an agency of the U.S. state of Delaware. The Secretary of Transportation is Nicole Majeski. The agency was established in 1917 and has its headquarters in Dover. The department's responsibilities include maintaining 89 percent of the state's public roadways (the Delaware State Route System) totaling 13,507 lane miles, snow removal, overseeing the "Adopt-A-Highway" program, overseeing E-ZPass Delaware, the Division of Motor Vehicles (DMV), and the Delaware Transit Corporation (known as DART First State). DelDOT maintains a 24/7 Traffic Management Center in Smyrna at the State Emergency Operations Center. At that location, they monitor traffic conditions, operate traffic lights, and broadcast on 1380 AM via WTMC radio.

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 ...

Cantilever Truss
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Engineers in the 19th century understood that a bridge that was continuous across multiple supports would distribute the loads among them. This would result in lower stresses in the girder or truss and meant that longer spans could be built. Several 19th-century engineers patented continuous bridges with hinge points mid-span. The use of a hinge in the multi-span system prese ... [...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 ...

Delaware Route 15
Delaware Route 15 (DE 15) is a state highway in the U.S. state of Delaware. The route runs from DE 14 west of Milford in Kent County north to DE 71/ DE 896 in Summit Bridge, New Castle County, just south of the Summit Bridge over the Chesapeake & Delaware Canal. DE 15 winds a path through many rural sections of Delaware, turning along many different roads. Most of the route, with the exception of the southern part of the route from Milford to Canterbury, runs to the west of U.S. Route 13 (US 13). DE 15 serves several cities and towns, including Wyoming, Dover, Clayton, and Middletown. The route intersects DE 12 near Felton, US 13 in Canterbury, DE 10 near Camden, DE 8 in Dover, DE 42 in Seven Hickories, DE 300 and DE 6 in the Clayton area, DE 299 in Middletown, and DE 286 near Summit Bridge.

Center Left-turn Lane
A reversible lane (British English: tidal flow) is a lane in which traffic may travel in either direction, depending on certain conditions. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notify drivers which lanes are open or closed to driving or turning. Reversible lanes are also commonly found in tunnels and on bridges, and on the surrounding roadways – even where the lanes are not regularly reversed to handle normal changes in traffic flow. The presence of lane controls allows authorities to close or reverse lanes when unusual circumstances (such as construction or a traffic mishap) require use of fewer or more lanes to maintain orderly flow of traffic. Separation of flows Some more recent implementations of reversible lanes use a movable barrier to establish a physical separation between allowed and disallowed lanes of travel. In some systems, a concrete barrier is moved during low-traffic peri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dogbone Interchange
A diamond interchange is a common type of road junction, used where a controlled-access highway crosses a minor road. Design The freeway itself is grade-separated from the minor road, one crossing the other over a bridge. Approaching the interchange from either direction, an off-ramp diverges only slightly from the freeway and runs directly across the minor road, becoming an on-ramp that returns to the freeway in similar fashion. The two places where the ramps meet the road are treated as conventional intersections. In the United States, where this form of interchange is very common, particularly in rural areas, traffic on the off-ramp typically faces a stop sign at the minor road, while traffic turning onto the freeway is unrestricted. The diamond interchange uses less space than most types of freeway interchange, and avoids the interweaving traffic flows that occur in interchanges such as the cloverleaf. Thus, diamond interchanges are most effective in areas where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Divided Highway
A dual carriageway ( BE) or divided highway ( AE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways. A road without a central reservation is a single carriageway regardless of the number of lanes. Dual carriageways have improved road traffic safety over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local/collector lanes are used within a local-express-lane system to provide more capacity and to smooth traffic flows for longer-distance travel. History A very early (perhaps the first) example of a dual carriageway was the ''Via Portuensis'', built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of t ...
