Big Rock Interchange
The Big Rock Interchange is the I-430/ I-630/Chenal Parkway interchange in west Little Rock, Arkansas. The name is derived from a large rock formation discovered during expansion. The interchange was originally constructed in 1977, then in the mid-2000s it was decided to expand the interchange in an attempt to alleviate congestion. In 2011 an outcropping of Pennsylvanian Jackfork Formation sandstone and surrounding shale was discovered in the southeast quadrant of the project. The formation was estimated to weigh about 5 million pounds. Due to the size and hardness of the sandstone it was decided to leave the unique and distinctive formation in place as a landmark, rather than use explosives or some other method to try to remove it, and it was dubbed "The Big Rock". When the original I-430 and I-630 interchange was constructed, about 14,000 vehicles a day traveled down each Interstate, and I-630 ended at a traffic signal at Shackleford Road. With expansion and growth in west Lit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interstate 430 (I-430) is a Interstate highway in Pulaski County, Arkansas, that bypasses the cities of Little Rock and North Little Rock. I-430 begins at an interchange southwest of Downtown Little Rock with I-30 and travels north to cross the Arkansas River and end at I-40. The first plans for the freeway appeared in 1955.

Interchange (road)
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 (road), intersection, where roads cross wikt:at-grade, at grade. Interchanges are almost always used when at least one road is a controlled-access highway (freeway) or a limited-access road, limited-access highway (expressway), though they are sometimes used at junctions between surface streets. Terminology ''Note:'' The descriptions of interchanges apply to countries where vehicles Left- and right-hand traffic, drive on the right side of the road. For left-side driving, the layout of junctions is mirrored. Both North American (NA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of Clay mineral, clay minerals (hydrous aluminium phyllosilicates, e.g., Kaolinite, kaolin, aluminium, Al2Silicon, Si2Oxygen, O5(hydroxide, OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers (Lamination (geology), laminae) less than one centimeter in thickness. This property is called ''Fissility (geology), fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks in ...

Chenal Valley
Chenal Valley ( ) is a sizable and more recently developed section of Little Rock, Arkansas, located in the west-central part of the city and serves as a major economic and residential hub in west Little Rock. Its name is derived from the area's Shinall Mountain, but Deltic Timber Corporation (now PotlatchDeltic), a major early developer of the area, opted to alter the name to mimic French language as part of a strategy (known as foreign branding) to orient the residential and commercial development toward upper-class population segments. The main thoroughfare is Chenal Parkway, mostly a divided four-lane path chiefly connecting Highway 10 to west Little Rock's Financial Centre business district. Chenal Parkway's northwestern terminus is just north of Arkansas 10 at Highway 300, near the Pinnacle Valley neighborhood. The southeastern terminus lies at Autumn Road at a transition to Financial Centre Parkway, with continuation to a conversion into Interstate 630 at Shackleford R ...

Overpass
An overpass, called an overbridge or flyover (for a road only) in the United Kingdom and some other Commonwealth countries, is a bridge, road, railway or similar structure that is over another road or railway. An ''overpass'' and '' underpass'' together form a grade separation. Stack interchanges are made up of several overpasses. History The world's first railroad flyover was constructed in 1843 by the London and Croydon Railway at Norwood Junction railway station to carry its atmospheric railway vehicles over the Brighton Main Line. Highway and road In North American usage, a ''flyover'' is a high-level overpass, built above main overpass lanes, or a bridge built over what had been an at-grade intersection. Traffic engineers usually refer to the latter as a '' grade separation''. A flyover may also be an extra ramp added to an existing interchange, either replacing an existing cloverleaf loop (or being built in place of one) with a higher, faster ramp that eventua ...
