Maryland Route 285
Maryland Route 285 (MD 285) is a state highway in the U.S. state of Maryland. The highway runs from MD 213 east through Chesapeake City to the Delaware state line in southern Cecil County. MD 285 consists of two sections. The first section parallels the north side of the Chesapeake & Delaware Canal; this portion was constructed around 1930. The other segment included sections of the main north–south highway through Chesapeake City, U.S. Route 213 (US 213). Sections of the main highway were constructed in the mid-1910s and then in the mid-1920s concurrent with the second bridge across the canal. After US 213 was moved to MD 213's present course using the Chesapeake City Bridge in 1949, the old highway became part of MD 537. That portion of MD 537 was replaced by an extension of MD 285 to MD 213 in 1983. Route description MD 285 begins at an intersection with MD 213 (Augustine Herman Highway) at the north end of the Chesapeake City Bridge. The highway heads east as two-la ...

Chesapeake City, Maryland
Chesapeake City is a town in Cecil County, Maryland, United States. The population was 736 at the 2020 census. The town was originally named by Bohemian colonist Augustine Herman the Village of Bohemia — or Bohemia Manor — but the name was changed in 1839 after the Chesapeake and Delaware Canal (C&D Canal) was built in 1829. Today, the town contains numerous old homes from that era that have been converted into bed and breakfasts, restaurants and the local historical museum. History The town was separated into north and south sections when the C&D Canal was built through the middle of the town. The two were connected by a drawbridge until 1942 when that was destroyed by a freighter that struck it. The current bridge opened in 1949. The new bridge had to be tall enough to allow supertankers to pass beneath it, resulting in a structure so high and long that cars no longer went into the city to cross the canal. Business declined for decades thereafter. Chesapeake City is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maryland Route 284
Maryland ( ) is a state in the Mid-Atlantic region of the United States. It shares borders with Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware and the Atlantic Ocean to its east. Baltimore is the largest city in the state, and the capital is Annapolis. Among its occasional nicknames are '' Old Line State'', the ''Free State'', and the ''Chesapeake Bay State''. It is named after Henrietta Maria, the French-born queen of England, Scotland, and Ireland, who was known then in England as Mary. Before its coastline was explored by Europeans in the 16th century, Maryland was inhabited by several groups of Native Americans – mostly by Algonquian peoples and, to a lesser degree, Iroquoian and Siouan. As one of the original Thirteen Colonies of England, Maryland was founded by George Calvert, 1st Baron Baltimore, a Catholic convert"George Calvert and Cecilius Calvert, Barons Baltimore" William Hand Browne, Nabu Pre ...

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] |
Vertical Lift Bridge
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. The counterweights in a vertical lift are only required to be equal to the weight of the deck, whereas bascule bridge counterweights must weigh several times as much as the span being lifted. As a result, heavier materials can be used in the deck, and so this type of bridge is especially suited for heavy railroad use. The biggest disadvantage to the vertical-lift bridge (in comparison with many other designs) is the height restriction for vessels passing under it, due to the deck remaining suspended above the passageway. Although most vertical-lift bridges use towers, each equipped with counterweights, some use hydraulic jacks located below the deck. ...

Maryland State Roads Commission
The Maryland State Highway Administration (abbreviated MDOT SHA or simply SHA) is the state transportation business unit responsible for maintaining Maryland's numbered highways outside Baltimore City. Formed originally under authority of the General Assembly of Maryland in 1908 as the State Roads Commission (S.R.C.), under the direction of the executive branch of state government headed by the Governor of Maryland, it is tasked with maintaining non-tolled/free bridges throughout the State, removing snow from the state's major thoroughfares, administering the State's "adopt-a-highway" program, and both developing and maintaining the State's freeway/expressway system. Since the reorganization of the several commissions, bureaus, boards, and assorted minor agencies with departments of the executive branch and establishment of the Governor's Cabinet in the early 1970s following the adoption of several individual reorganization recommendations after the rejection by the voters in a N ...

Reverse Curve
In civil engineering, a reverse curve (or "S" curve) is a section of the horizontal alignment of a highway or railroad route in which a curve to the left or right is followed immediately by a curve in the opposite direction. On highways in the United States reverse curves are often announced by the posting of a W1-4L sign (left-right reverse curve) or a W1-4R sign (right-left reverse curve), as called for in the Manual on Uniform Traffic Control Devices. Reverse curves on the Northeast Corridor in the USA hinder the development of high-speed rail. Reverse curves cause buffer-locking. See also *S bridge * Road curve *Track geometry Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, construction and maintenance of t ... References Railway track layouts {{engineering-stub ...

Delaware
Delaware ( ) is a state in the Mid-Atlantic region of the United States, bordering Maryland to its south and west; Pennsylvania to its north; and New Jersey and the Atlantic Ocean to its east. The state takes its name from the adjacent Delaware Bay, in turn named after Thomas West, 3rd Baron De La Warr, an English nobleman and Virginia's first colonial governor. Delaware occupies the northeastern portion of the Delmarva Peninsula and some islands and territory within the Delaware River. It is the second-smallest and sixth-least populous state, but also the sixth-most densely populated. Delaware's largest city is Wilmington, while the state capital is Dover, the second-largest city in the state. The state is divided into three counties, having the lowest number of counties of any state; from north to south, they are New Castle County, Kent County, and Sussex County. While the southern two counties have historically been predominantly agricultural, New Castle is more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maryland Route 537
Maryland Route 537 (MD 537) is a collection of unsigned highway, unsigned state highways in the U.S. state of Maryland. These two existing highways and two former sections of state highway are segments of the old alignment of U.S. Route 213 (US 213), which is now Maryland Route 213, MD 213, in Chesapeake City, Maryland, Chesapeake City in southern Cecil County, Maryland, Cecil County. Some of the roads that became segments of MD 537 were constructed in the mid-1910s as part of the original state road between Elkton, Maryland, Elkton and Cecilton, Maryland, Cecilton. Other portions of MD 537 were part of the approach roads to a bridge across the Chesapeake & Delaware Canal that was built in the mid-1920s and destroyed in 1942. After the modern Chesapeake City Bridge and its approach roads were completed in 1949, US 213 was moved to the new bridge and approach roads and MD 537 was assigned to the bypassed sections of US 213. Much of MD 537 outside of Chesapeake City was transferred t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
