Lloyd Expressway
The Lloyd Expressway is a major east-west Highway, traffic artery located in Vanderburgh County, Indiana. The route primarily runs through Evansville, Indiana, reaching from Interstate 69 in Indiana, Interstate 69 on the east side of the city to the Posey County, Indiana, Posey County line west of the city limits. West of U.S. Route 41 in Indiana, US 41, the expressway is signed as Indiana State Road 62 (SR 62). East of US 41, it is signed as Indiana State Road 66 (SR 66). History Before the expressway was built, east-west traffic across Evansville was handled by a pair of streets: Division Street to the east of Main Street, and Pennsylvania Avenue to the west. These roads were congested and dangerous. For a short stretch, Division Street ran in tandem with a busy railroad track. The unacceptable condition of this route necessitated an expressway. The road was built in stages. The west section of the expressway was completed in the 1950s, ending at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indiana Department Of Transportation
The Indiana Department of Transportation (INDOT) is a governmental agency of the U.S. state of Indiana charged with maintaining and regulating transportation and transportation related infrastructure such as state owned airports, List of numbered roads in Indiana, state highways and state owned canals or railroads. Indiana's "highway network" started out as a series of dirt paths, which settlers created for local travel. Most of the time, these paths did not interconnect, making travel difficult at best. Highway Act – 1917 The first Indiana legislative step toward establishing a state highway commission that would meet the requirements for federal road grants was taken on March 7, 1917. But, aside from blazing a new trail, the newly organized State Highway Commission accomplished little of practical nature, because the constitutionality of the act creating the commission was challenged in the courts. Highway Act – 1919 By the time that the 1917 Highway Act was ruled constit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intersection (road)
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design. Types Road segments One way to classify intersections is by the number of road segments (arms) that are involved. * A three-way intersection is a junction between three road segments (arms): a T junction when two arms form one road, or a Y junction, the latter also known as a fork if approached from the stem of the Y. * A four-way intersection, or crossroads, usually involves a crossing over of two streets or roads. In areas where there are blocks and in some other cases, the crossing streets or roads are perpendicular to each other. However, two roads may cross at a different angle. In a few cases, the junction of two road segments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-point Urban Interchange
A single-point urban interchange (SPUI, or ), also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space safely and efficiently. Description A SPUI is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road. The term "single-point" refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic signals. Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is being used extensively in the reconstruction of existing freeways as well as constructing new freeways, p ...

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] |

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] |

Right-in/right-out
Right-in/right-out (RIRO) and left-in/left-out (LILO) refer to a type of three-way road intersection where turning movements of vehicles are restricted. A RIRO permits only right turns and a LILO permits only left turns. "Right-in" and "left-in" refer to turns from a main road ''into'' an intersection (or a driveway or parcel); "right-out" and "left-out" refer to turns ''from'' an intersection (or a driveway or parcel) to a main road. RIRO is typical when vehicles drive on the right, and LILO is usual where vehicles drive on the left. This is because minor roads usually connect to the outsides of two-way roads. However, on a divided highway, both RIRO and LILO intersections can occur. The remainder of this article refers only to RIRO but applies equally to LILO. A RIRO intersection differs from a 3/4 intersection (right in/right out/left in) and an unrestricted intersection. Design RIRO is an important tool of access management, itself an important component of transport ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual Carriageway
A dual carriageway ( BE) or divided highway ( AE) is a class of highway with carriageways for traffic travelling in opposite directions separated by a central reservation (BrE) or median (AmE). Roads with two or more carriageways which are designed to higher standards with controlled access are generally classed as motorways, freeways, etc., rather than dual carriageways. A road without a central reservation is a single carriageway regardless of the number of lanes. Dual carriageways have improved road traffic safety over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local/collector lanes are used within a local-express-lane system to provide more capacity and to smooth traffic flows for longer-distance travel. History A very early (perhaps the first) example of a dual carriageway was the ''Via Portuensis'', built in the first century by the Roman emperor Claudius between Rome and its port Ostia at the mouth of t ...
