Interstate 81 In Maryland
Interstate 81 (I-81) is a part of the Interstate Highway System that runs from Dandridge, Tennessee, to Fishers Landing, New York. In Maryland, the Interstate Highway runs from the West Virginia state line at the Potomac River in Williamsport north to the Pennsylvania state line near Maugansville. I-81 is the primary north–south Interstate Highway in Washington County, connecting Hagerstown with Chambersburg and Harrisburg to the north and Martinsburg, Winchester, and Roanoke to the south. The idea of a north–south bypass of Hagerstown to relieve congestion on the contemporary main highway through the Hagerstown Valley, US Route 11 (US 11), predates the Interstate Highway System. Construction on the Hagerstown Bypass began in the mid-1950s and was completed in 1958 from US 40 north to the Pennsylvania state line. I-81 was assigned to the new freeway in 1959. The southern section of the freeway from the Potomac River to US 40 was built star ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Highway Administration
The Federal Highway Administration (FHWA) is a division of the United States Department of Transportation that specializes in highway transportation. The agency's major activities are grouped into two programs, the Federal-aid Highway Program and the Federal Lands Highway Program. Its role had previously been performed by the Office of Road Inquiry, Office of Public Roads and the Bureau of Public Roads. History Background The organization has several predecessor organizations and complicated history. The Office of Road Inquiry (ORI) was founded in 1893. In 1905, that organization's name was changed to the Office of Public Roads (OPR) which became a division of the United States Department of Agriculture. The name was changed again to the Bureau of Public Roads in 1915 and to the Public Roads Administration (PRA) in 1939. It was then shifted to the Federal Works Agency which was abolished in 1949 when its name reverted to Bureau of Public Roads under the Department of Commerce ...

Maryland Route 144
Maryland Route 144 (MD 144) is a collection of state highways in the U.S. state of Maryland. These highways are sections of old alignment of U.S. Route 40 (US 40) between Cumberland and Baltimore. Along with US 40 Scenic, US 40 Alternate, and a few sections of county-maintained highway, MD 144 is assigned to what was once the main highway between the two cities, connecting those endpoints with Hancock, Hagerstown, Frederick, New Market, Mount Airy, Ellicott City, and Catonsville. MD 144 has seven disjoint sections of mainline highway that pass through the Appalachian Mountains in Allegany and Washington counties and the rolling Piedmont of Frederick, Carroll, Howard, and Baltimore counties. Route description There are seven mainline sections of MD 144: *MD 144 in Allegany County runs from MD 807 in Cumberland east to US 40 Scenic east of Flintstone.

Lurgan Subdivision
The Lurgan Subdivision is a railroad line owned and operated by CSX Transportation in the U.S. states of Pennsylvania, Maryland, and West Virginia. The line runs from Chambersburg, Pennsylvania, south to Hagerstown, Maryland, and west to Cherry Run, West Virginia, along a former Western Maryland Railway line. It meets the Hanover Subdivision at Hagerstown and the Cumberland Subdivision at Cherry Run. The line is named after its former northern end in Lurgan Township, Franklin County, Pennsylvania, where the Western Maryland once connected to the Reading Company along the Alphabet Route. History The Western Maryland Railway, which had a main line from Baltimore to Williamsport, Maryland, made its first expansion into Pennsylvania in 1881. The WM leased a line from the Baltimore and Cumberland Valley Rail Road and the Baltimore & Cumberland Valley Rail Road Extension Company, connecting Edgemont, Maryland to Shippensburg, Pennsylvania. In 1886 the line was connected in Shippensb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSX Transportation
CSX Transportation , known colloquially as simply CSX, is a Class I freight railroad operating in the Eastern United States and the Canadian provinces of Ontario and Quebec. The railroad operates approximately 21,000 route miles () of track. The company operates as the leading subsidiary of CSX Corporation, a Fortune 500 company headquartered in Jacksonville, Florida.

Interstate 68 In Maryland
Interstate 68 (I-68) is a Interstate Highway in the US states of West Virginia and Maryland, connecting I-79 in Morgantown, West Virginia, to 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 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. US 219 and US 220 overlap I-68 in Garrett County and Cumberland, respectively, and US 40 overlaps with the freeway from Keysers Ridge to the eastern end of the freeway at Hancock. The construction of I-68 began in 1965 and continued for over 25 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloverleaf Interchange
A cloverleaf interchange is a two-level interchange in which all turns are handled by slip roads. To go left (in right-hand traffic; reverse directions in left-driving regions), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270°) and merge onto the intersecting road. The objective of a cloverleaf is to allow two highways to cross without the need for any traffic to be stopped by traffic lights. The limiting factor in the capacity of a cloverleaf interchange is traffic weaving. Overview Cloverleaf interchanges, viewed from overhead or on maps, resemble the leaves of a four-leaf clover or less often a 3-leaf clover. In the United States, cloverleaf interchanges existed long before the Interstate system. They were originally created for busier interchanges that the original diamond interchange system could not handle. Their chief advantage was that they were free-flowing and did not require t ...

Partial Cloverleaf Interchange
A partial cloverleaf interchange or parclo is a modification of a cloverleaf interchange. The design has been well received, and has since become one of the most popular freeway-to-arterial interchange designs in North America. It has also been used occasionally in some European countries, such as Germany, Hungary, Italy, the Netherlands, and the United Kingdom. Comparison with other interchanges *A diamond interchange has four ramps. *A cloverleaf interchange has eight ramps, as does a stack interchange. They are fully grade separated, unlike a parclo, and have traffic flow without stops on all ramps and throughways. *A parclo generally has either four or six ramps but less commonly has five ramps. Naming In Ontario, the specific variation is identified by a letter/number suffix after the name. Ontario's naming conventions are used in this article. The letter ''A'' designates that two ramps meet the freeway ''ahead'' of the arterial road, while ''B'' designates that two ram ...

Diamond 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] |
Maryland Route 63
Maryland Route 63 (MD 63) is a state highway in the U.S. state of Maryland. The state highway runs from MD 65 in Fairplay north to the Pennsylvania state line near Cearfoss, where the highway continues as Pennsylvania Route 163 (PA 163). MD 63 is an L-shaped route that passes through central Washington County on the south and west sides of Hagerstown. The state highway connects with multiple local and long-distance highways that serve Hagerstown, including Interstate 81 (I-81) and U.S. Route 11 (US 11) in Williamsport and I-70 and US 40 in Huyett. MD 63 also joins MD 68 in a concurrency through Williamsport. The Spielman Road portion of MD 63 was constructed in two segments from Spielman to Downsville and from there to Williamsport in the mid 1910s and early 1930s, respectively. The Greencastle Pike portion of MD 63, which follows a former turnpike, was constructed as MD 398 from Williamsport to Cearfoss in the early 1930s. MD 63 was extended to its present ter ...
