Figueroa Street Tunnels
The Figueroa Street Tunnels are a set of four four-lane tunnels that carry northbound traffic on State Route 110 (the Arroyo Seco Parkway) through Elysian Park in Los Angeles, California, United States. From south to north, the four tunnels measure 755, 461, 130, and 405 feet (230, 141, 40, and 123 m) in length, 46.5 feet (14 m) in width, and 28.3 ft (8.6 m) in height. The north three tunnels opened in 1931 as a bypass to a section of North Broadway; the southernmost (and longest) opened in 1935, connecting to Figueroa Street downtown. In 1943, the Figueroa Street Viaduct was built to the north of the tunnels. This dedicated the tunnels to 4 lanes of eastward traffic, and the viaduct to 4 lanes of westward traffic. Several connections have been added to the street, most notably in 1940 to the Arroyo Seco Parkway and in 1953 to the Four Level Interchange. The tunnels were designed by engineer Merrill Butler, who was responsible for many iconic Los Angeles River bridges - not ...

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, 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 juncti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Ana Freeway
The Santa Ana Freeway is one of the principal freeways in Southern California, connecting Los Angeles and its southeastern suburbs including the freeway's namesake, the city of Santa Ana. The freeway begins at its junction with the San Diego Freeway ( Interstate 405, I-405), called the El Toro Y, in Irvine, signed as I-5. From there, it generally goes southeast to northwest to the East Los Angeles Interchange, where it takes the designation of U.S. Route 101 (US 101). It then proceeds northwest to the Four Level Interchange (also known as the Bill Keene Memorial Interchange) in downtown Los Angeles. Formerly, the entirety of the route was marked as US 101 until the 1964 highway renumbering, which truncated US 101 to the East Los Angeles Interchange and designated the rest of the freeway as I-5. North of the East Los Angeles Interchange complex, I-5 follows the Golden State Freeway. South of the El Toro Y, I-5 takes on the San Diego Freeway name from I-405. An ab ...

Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-cut
In civil engineering, a cut or cutting is where soil or rock from a relative rise along a route is removed. The term is also used in river management to speed a waterway's flow by short-cutting a meander. Cuts are typically used in road, rail, and canal construction to reduce the length and grade of a route. Cut and fill construction uses the spoils from cuts to fill in defiles to cost-effectively create relatively straight routes at steady grades. Cuts are used as alternatives to indirect routes, embankments, or viaducts. They also have the advantage of comparatively lower noise pollution than elevated or at-grade solutions. History The term ''cutting'' appears in the 19th century literature to designate rock cuts developed to moderate grades of railway lines. ''Railway Age's Comprehensive Railroad Dictionary'' defines a cut as "a passage cut for the roadway through an obstacle of rock or dirt." Creation Cuts can be created by multiple passes of a shovel, grader, scrap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
At-grade Intersection
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] |
Freeway
A controlled-access highway is a type of highway that has been designed for high-speed vehicular traffic, with all traffic flow—ingress and egress—regulated. Common English terms are freeway, motorway and expressway. Other similar terms include '' throughway'' and '' parkway''. Some of these may be limited-access highways, although this term can also refer to a class of highways with somewhat less isolation from other traffic. In countries following the Vienna convention, the motorway qualification implies that walking and parking are forbidden. A fully controlled-access highway provides an unhindered flow of traffic, with no traffic signals, intersections or property access. They are free of any at-grade crossings with other roads, railways, or pedestrian paths, which are instead carried by overpasses and underpasses. Entrances and exits to the highway are provided at interchanges by slip roads (ramps), which allow for speed changes between the highway and arter ...

San Fernando Road
San Fernando Road is a major street in the City of Los Angeles and Los Angeles County. Within the Burbank city limits it is signed as San Fernando Boulevard, and north of Newhall Pass it is signed as The Old Road. It was previously designated as Business Loop 5 in the 1970s.

Highland Park, Los Angeles, California
Highland Park is a neighborhood in Los Angeles, California, located in the city's Northeast region. It was one of the first subdivisions of Los Angeles and is inhabited by a variety of ethnic and socioeconomic groups. History The area was settled thousands of years ago by Paleo-Indians, and would later be settled by the Kizh. After the founding of Los Angeles in 1781, the Corporal of the Guard at the Mission San Gabriel Arcángel, Jose Maria Verdugo, was granted the 36,403 acre Rancho San Rafael which included present day Highland Park. Drought in the mid-19th century resulted in economic hardship for the Verdugo family, which eventually compelled them to auction off Rancho San Rafael in 1869 for $3,500 over an unpaid loan. The San Rafael tract was purchased by Andrew Glassell and Albert J. Chapman, who leased it out to sheep herders. In 1885, during the 1880s land boom, it was sold to George Morgan and Albert Judson, who combined it with other parcels they had purchased from ...
