Interstate 675 (Ohio)
Interstate 675 (I-675) is an auxiliary Interstate Highway in the suburbs of Dayton in the US state of Ohio. I-675 serves as an eastern bypass of Dayton that is long. As originally proposed, the route was to reconnect with I-75 north of Dayton near Northridge rather than going east toward Springfield and I-70 (this was later rejected because part of the right-of-way would have gone through Wright-Patterson Air Force Base). Construction was completed in 1987, though some have lobbied to extend the highway west of Dayton. Route description From the south, the highway begins at a semi-directional T interchange with I-75 in Miami Township, with four lanes. Next, there is a modified split diamond interchange with State Route 725 (SR 725) in Washington Township; ramps to and from the south connect to SR 725, with an additional directional loop ramp from eastbound SR 725 to northbound I-675; ramps to and from the north connect to Yankee Street.

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 ...

Semi-directional T Interchange
In the field of road transport, an interchange (American English) or a grade-separated junction (British English) is a road junction that uses grade separations to allow for the movement of traffic between two or more roadways or highways, using a system of interconnecting roadways to permit traffic on at least one of the routes to pass through the junction without interruption from crossing traffic streams. It differs from a standard intersection, where roads cross at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway or motorway) or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets. Terminology ''Note:'' The descriptions of interchanges apply to countries where vehicles drive on the right side of the road. For left-side driving, the layout of junctions is mirrored. Both North American (NA) and British (UK) terminology is included. ; Freeway junction, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Half-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 separation, grade-separated from the minor road, one crossing the other over a bridge. Approaching the interchange (road), 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 Interchange (road), ramps meet the road are treated as conventional intersection (road), 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 grade separation#Weaving, interweaving traffic flows that occur in ...

Ohio State Route 48
State Route 48 (SR 48) is a north–south highway in Ohio that runs from SR 132 near Goshen to SR 66 near Houston, passing through Dayton. Commemorative designations On February 15, 2005, Governor Bob Taft signed Senate Bill 156, which designated SR 48 as the U.S.A.F. Pararescue Memorial Parkway. The route runs near the hometowns of four pararescuemen who were killed in action: William H. Pitsenbarger of Piqua, Sgt. Jim Locker of Sidney, Master Sgt. William McDaniel II of Greenville, and Airman 1st Class James Pleiman of Russia. Memorial markers are installed as far south as Goshen Township in Clermont County.

Two-way Street
A two-way street is a street that allows vehicles to travel in both directions. On most two-way streets, especially main streets, a line is painted down the middle of the road to remind drivers to stay on their side of the road. Sometimes one portion of a street is two-way and the other portion is one-way. If there is no line, a car must stay on the appropriate side and watch for cars coming in the opposite direction and prepare to pull over to let them pass. See also * Dual carriageway * One-way traffic One-way traffic (or uni-directional traffic) is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way traffic, or designed to direct vehicles to move in one direction. One-way streets typical ... References * {{road-stub Types of roads ...

Frontage Road
A frontage road (also known as an access road, outer road, service road, feeder road, or parallel road) is a local road running parallel to a higher-speed, limited-access road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. Where parallel high-speed roads are provided as part of a major highway, these are also known as local-express lanes. A frontage lane is a paved path that is used for the transportation and travel from one street to another. Frontage lanes, closely related to a frontage road, are common in metropolitan areas and in small rural towns. Frontage lanes are technically not classified as roads due to their purpose as a bridge from one road to another, and due to the architectural standards that they are not as wide as a standard road, or used as commonly as a standard road, street, or avenue. Overview Frontage roads provide access to homes and businesses which would otherwise be cut off by a limited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
One-way Traffic
One-way traffic (or uni-directional traffic) is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way traffic, or designed to direct vehicles to move in one direction. One-way streets typically result in higher traffic flow as drivers may avoid encountering oncoming traffic or turns through oncoming traffic. Residents may dislike one-way streets due to the circuitous route required to get to a specific destination, and the potential for higher speeds adversely affecting pedestrian safety. Some studies even challenge the original motivation for one-way streets, in that the circuitous routes negate the claimed higher speeds. Signage General signs Signs are posted showing which direction the vehicles can move in: commonly an upward arrow, or on a T junction where the main road is one-way, an arrow to the left or right. At the end of the street through which vehicles may not enter, a prohibitory traffic sign "Do Not Enter", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
