Brunswick Bridge
Maryland Route 17 (MD 17) is a state highway in the U.S. state of Maryland. The state highway begins at the Virginia state line at the Potomac River in Brunswick, where the highway continues south as Virginia State Route 287 (SR 287). MD 17 runs north from the Brunswick Bridge to the Frederick–Washington county line near Wolfsville. The state highway serves as the main north–south highway of the Middletown Valley of western Frederick County. MD 17 connects Brunswick and Wolfsville with Rosemont, Burkittsville, Middletown, and Myersville. The state highway also connects those communities with the valley's main east–west highways, which include U.S. Route 340 (US 340), US 40 Alternate, Interstate 70 (I-70), and US 40. What is now MD 17 was originally designated MD 33. The first sections of the state highway were constructed in Brunswick and Rosemont in 1916. MD 33 was mostly constructed south of Myersville in the early 1920s; the last pieces of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middletown Valley
Middletown Valley, also historically known as Catoctin Valley, is a valley in western Frederick County in the state of Maryland. Geography It is bound to the west by South Mountain, to the east by Catoctin Mountain, to the south by the Potomac River and to the north by the convergence of South Mountain and Catoctin Mountain, south of Quirauk Mountain. Geographically, it can be considered an extension of the Loudoun Valley which lies below the Potomac in Virginia. The valley derives its name from Middletown, the largest town in the Valley. The use of the ''Catoctin Valley'' terminology was prevalent up through the American Civil War The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states ... but afterwards was abandoned due to confusion between it and the northern portion of the Loudo ...

Chesapeake And Ohio Canal National Historical Park
The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the state of Maryland. The park was established in 1961 as a National Monument by President Dwight D. Eisenhower to preserve the neglected remains of the Chesapeake and Ohio Canal and many of its original structures. The canal and towpath trail extends along the Potomac River from Georgetown, Washington, D.C., to Cumberland, Maryland, a distance of . In 2013, the path was designated as the first section of U.S. Bicycle Route 50. The Chesapeake and Ohio Canal Construction on the Chesapeake and Ohio Canal (also known as "the Grand Old Ditch" or the "C&O Canal") began in 1828 and ended in 1850 when the canal reached Cumberland, far short of its intended destination of Pittsburgh, Pennsylvania. Occasionally there was talk of extending the 184.5-mile canal: for example, an 1874 proposal to dig an 8.4-mile tunnel through the Allegheny Mountains, and there was a tunnel built to connect with ...

Roundabout
A roundabout is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.''The New Shorter Oxford English Dictionary,'' Volume 2, Clarendon Press, Oxford (1993), page 2632 Engineers use the term modern roundabout to refer to junctions installed after 1960 that incorporate various design rules to increase safety. Both modern and non-modern roundabouts, however, may bear street names or be identified colloquially by local names such as rotary or traffic circle. Compared to stop signs, traffic signals, and earlier forms of roundabouts, modern roundabouts reduce the likelihood and severity of collisions greatly by reducing traffic speeds and minimizing T-bone and head-on collisions. Variations on the basic concept include integration with tram or train lines, two-way flow, higher speeds and many others. For pedestrians, traffic exiting th ...

Metropolitan Subdivision
The Metropolitan Subdivision is a railroad line owned and operated by CSX Transportation in the District of Columbia and the U.S. state of Maryland. The 79-mile line runs from Washington, D.C., northwest to Weverton, Maryland, along the former Metropolitan Branch of the Baltimore and Ohio Railroad.CSX Transportation"Northern Region, Baltimore Division, Timetable No. 4." Effective 2005-01-01. At its southeast end, north of Union Station, the Metropolitan Subdivision meets the Capital Subdivision (formerly called the B&O Washington Branch) and Amtrak's Northeast Corridor. It meets the Old Main Line Subdivision at Point of Rocks, Maryland. At its northwest end in Weverton, the line joins the Cumberland Subdivision. MARC Train's Brunswick Line uses the entire subdivision, as does Amtrak's ''Capitol Limited''. The Red Line of the Washington Metro shares right-of-way with the subdivision along two separate stretches in Maryland and D.C.: from the junction with the Capital Subdivi ...

Chesapeake And Ohio Canal
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River between Washington, D.C. and Cumberland, Maryland. It replaced the Potomac Canal, which shut down completely in 1828, and could operate during months in which the water level was too low for the former canal. The canal's principal cargo was coal from the Allegheny Mountains. Construction on the canal began in 1828 and ended in 1850 with the completion of a stretch to Cumberland, although the Baltimore and Ohio Railroad had already reached Cumberland in 1842. Rising and falling over an elevation change of , it required the construction of 74 Lock (water transport), canal locks, 11 Navigable aqueduct, aqueducts to cross major streams, more than 240 culverts to cross smaller streams, and the Paw Paw Tunnel. A planned section to the Ohio River at Pittsburgh was never built. The canalway is now maintained as the Chesapeake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girder Bridge
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box. The term "girder" is often used interchangeably with "beam" in reference to bridge design. However, some authors define beam bridges slightly differently from girder bridges. A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold. Due to the properties of the second moment of area, the height of a girder is the most significant factor to affect its load capacity. Longer spans, more traffic, or wider spacing o ...

Lovettsville, Virginia
Lovettsville is a town in Loudoun County, located near the very northern tip of the Commonwealth of Virginia, United States. Settled primarily by German immigrants, the town was originally established in 1836. The population was 1,613 at the 2010 census and an estimated 2,198 in 2019. History Following the 1722 Treaty of St. Albans which established the Blue Ridge Mountains as the buffer between Native Americans and white settlers, German immigrants began arriving in the northern Loudoun Valley to farm the rich topsoil. They established several villages, many constructed of log and wooden buildings, and began to expand their land holdings. Lovettsville was then called "The German Settlement". In 1820 David Lovett subdivided his property into quarter-acre "city lots". As a result of the ensuing construction boom, the town was called "Newtown". In 1828, the town was again renamed, to "Lovettsville". In 1836 the Virginia General Assembly established Lovettsville as a town, but the ...
