Interstate 68 (West Virginia)
Interstate 68 (I-68) is a Interstate Highway System, Interstate Highway in the US states of West Virginia and Maryland, connecting Interstate 79 in West Virginia, I-79 in Morgantown, West Virginia, to Interstate 70 in Maryland, I-70 in Hancock, Maryland. I-68 is also Corridor E of the Appalachian Development Highway System. From 1965 until the freeway's construction was completed in 1991, it was designated as U.S. Route 48 (US 48). In Maryland, the highway is known as the National Freeway, an homage to the historic National Road, which I-68 parallels between Keysers Ridge, Maryland, Keysers Ridge and Hancock. The freeway mainly spans rural areas and crosses numerous mountain ridges along its route. A road cut at Sideling Hill exposed geological features of the mountain and has become a tourist attraction. U.S. Route 219 in Maryland, US 219 and U.S. Route 220 in Maryland, US 220 concurrency (road), overlap I-68 in Garrett County, Maryland, Garrett Count ...

Allegany County is located in the northwestern part of the U.S. state of Maryland. As of the 2020 census, the population was 68,106. Its county seat is Cumberland. The name ''Allegany'' may come from a local Lenape word, ''welhik hane'' or ''oolikhanna,'' which means 'best flowing river of the hills' or 'beautiful stream'. A number of counties and a river in the Appalachian region of the U.S. are named ''Allegany'', ''Allegheny'', or ''Alleghany''. Allegany County is part of the Cumberland, MD-WV Metropolitan Statistical Area. It is a part of the Western Maryland " panhandle". History The western part of Maryland (including the present Allegany County) was originally part of Prince George's County when Maryland was formed in 1696.

Moundsville, West Virginia
Moundsville is a city in Marshall County, West Virginia, United States, along the Ohio River. It is part of the Wheeling, West Virginia metropolitan area. The population was 8,122 at the 2020 census. It is the county seat of Marshall County. The city was named for the nearby ancient Grave Creek Mound, constructed 250 to 100 BC by indigenous people of the Adena culture.

Ohio Valley
The Ohio River is a long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from western Pennsylvania to its mouth on the Mississippi River at the southern tip of Illinois.

It is also the 6th oldest river on the North American continent. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for five million people. The lower Ohio River just below Louisville is obstructed by rapids known as the Falls of the Ohio where the elevation falls in restricting larger commercial navigation, although in the 18th a ...

Concurrency (road)
A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex (two concurrent routes), triplex (three concurrent routes), multiplex (any number of concurrent routes), dual routing or triple routing. Concurrent numbering can become very common in jurisdictions that allow it. Where multiple routes must pass between a single mountain crossing or over a bridge, or through a major city, it is often economically and practically advantageous for them all to be accommodated on a single physical roadway. In some jurisdictions, however, concurrent numbering is avoided by posting only one route number on highway signs; these routes disappear at the start of the concurrency and reappear when it ends. However, any route that becomes unsigned in the middle of the concurren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sideling Hill
Sideling Hill, also Side Long Hill, is a long, steep, narrow mountain ridge in the Ridge-and-Valley (or Allegheny Mountains) physiographic province of the Appalachian Mountains, located in Washington County in western Maryland and adjacent West Virginia and Pennsylvania, USA. The highest point on the ridge is Fisher Point, at in Fulton County, Pennsylvania. Geology Sideling Hill is a syncline mountain, in a region of downward-folded ( synclinal) rock strata between two upfolded anticlines. The ridge is capped by an erosion-resistant conglomerate and sandstone of Mississippian (early Carboniferous) geologic age, the Purslane Sandstone of the Pocono Formation. The ridge's slopes are formed of much more easily eroded kinds of rock, including the Devonian- Mississippian Rockwell Formation, with long, narrow valleys paralleling the ridge on either side. Ecology Most of the crest of Sideling Hill is forested, primarily with various deciduous tree species such as oaks (''Qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Road
The National Road (also known as the Cumberland Road) was the first major improved highway in the United States built by the Federal Government of the United States, federal government. Built between 1811 and 1837, the road connected the Potomac River, Potomac and Ohio Rivers and was a main transport path to the Western United States, West for thousands of settlers. When improved in the 1830s, it became the second U.S. road surfaced with the macadam process pioneered by Scotsman John Loudon McAdam. Construction began heading west in 1811 at Cumberland, Maryland, on the Potomac River. After the panic of 1837, Financial Panic of 1837 and the resulting economic depression, congressional funding ran dry and construction was stopped at Vandalia, Illinois, the then-capital of Illinois, northeast of St. Louis, Missouri, St. Louis across the Mississippi River. The road has also been referred to as the Cumberland Turnpike, the Cumberland–Brownsville Turnpike (or Road or Pike), the ...

Appalachian Development Highway System
The Appalachian Development Highway System (ADHS) is a series of highway corridors in the Appalachia region of the eastern United States. The routes are designed as local and regional routes for improving economic development in the historically isolated region. It was established as part of the Appalachian Regional Development Act of 1965, and has been repeatedly supplemented by various federal and state legislative and regulatory actions. The system consists of a mixture of state, U.S., and Interstate routes. The routes are formally designated as "corridors" and assigned a letter. Signage of these corridors varies from place to place, but where signed are often done so with a distinctive blue-colored sign. A 2019 study found that the construction of the ADHS led to economic net gains of $54 billion (approximately 0.4 percent of national income) and boosted incomes in the Appalachian region by reducing the costs of trade. History In 1964, the President's Appalachian Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 70 In Maryland
Interstate 70 (I-70) is a part of the Interstate Highway System that runs from Cove Fort, Utah, to Baltimore, Maryland. In Maryland, the Interstate Highway runs from the Pennsylvania state line in Hancock east to the Interstate's eastern terminus near its junction with I-695 at a park and ride in Baltimore. I-70 is the primary east–west Interstate in Maryland; the Interstate Highway connects Baltimore—and Washington, DC, via I-270—with Western Maryland. The Interstate serves Frederick and Hagerstown directly and provides access to Cumberland via its junction with I-68 at Hancock. I-70 runs concurrently with its predecessor highway, U.S. Route 40 (US 40), from Hancock to Indian Springs in Washington County and from Frederick to West Friendship in Howard County. I-70's route from Frederick to West Friendship was constructed as a divided highway relocation of US 40 in the early to mid-1950s and a freeway bypass of Frederick in the late 1950s. Th ...
