44-461: The Suitland Parkway is a limited-access parkway in Washington, D.C. , and Prince George's County, Maryland , administered and maintained by the U.S. National Park Service (NPS), National Capital Parks-East . The road has partial controlled access with a combination of interchanges and at-grade intersections, but without property access for neighboring land-owners. Conceived in 1937, it

88-549: A fairly recent addition to a complex network of roads. China's first expressway was built in 1988. Until 1993, very few expressways existed. The network is expanding rapidly after 2000. In 2011, 11,000 kilometres (6,800 mi) of expressways were added to the network. The Expressways of Pakistan are a network of multiple-lane, high-speed highways in Pakistan, which are owned, maintained and operated federally by Pakistan's National Highway Authority . They are one class lower than

132-412: A four-lane divided highway . The road intersects Firth Sterling Avenue SE at a traffic light before passing near residential areas as a limited-access road and curving to the south. Just after Firth Sterling Avenue SE, the parkway used to intersect a railroad line at a road crossing. The tracks have been abandoned and removed, but signage for the old railroad crossing can still be seen. The parkway comes to

176-537: A full interchange with Alabama Avenue SE, with access to and from the westbound direction of the parkway provided by Irving Street SE. Following this, the parkway heads east into woods. At the bridge that carries Southern Avenue SE over the parkway, the Suitland Parkway enters Prince George's County in Maryland . The road heads northeast into Temple Hills , coming to traffic light with MD 637 north of

220-581: A maximum design speed of more than 60 km/h (37 mph), excluding pedestrian, bicycle, moped or tractor traffic. Oversized vehicles are banned. The construction of transregional Kraftfahrstraßen highways ( Autostraßen ) rank below the standard of German autobahns . With regard to the general German speed limits , on roads with lanes separated by a median or with a minimum of two marked lanes per direction, an advisory speed limit ( Richtgeschwindigkeit ) of 130 km/h (81 mph) applies. At-grade intersections are admissible, regulation at junctions

264-850: A space that is not accessible to vehicles, the drivers may not drive on the lane opposite to them. In Croatia , the term brza cesta (lit. "fast road") is used to describe a motor vehicle-only road, usually grade-separated , without an emergency lane , with a speed limit of 110 km/h (68 mph), although it can be lowered, usually to 70 or 90 km/h (43 or 56 mph). They range from 2+2 lane dual carriageways with grade-separated intersections and 110 km/h (68 mph) speed limit ( D2 in Osijek ), four or six-lane urban streets with at-grade intersections with traffic lights ( D1 in Karlovac ) or two-lane single carriageways with grade-separated intersections ( D33 in Šibenik ). They are either

308-610: A standalone state road ( D10 ) or a part of one (Southern Osijek bypass, D2 ). Some portions of motorways are expressways since they are either in construction ( A8 between Pazin and Matulji ) or designed as such ( A7 in Rijeka ). As a rule, the expressways are not tolled, however major tunnels on expressways are tolled. Expressways in the Czech Republic ( Czech : Silnice pro motorová vozidla , are defined as dual carriageways with smaller emergency lane. The speed limit

352-530: A westbound exit for Sheridan Road SE and an eastbound entrance from Sumner Road SE. that provides access to Martin Luther King, Jr. Avenue SE . At the intersection of Sheridan Road SE and Pomeroy Road SE, a bike path begins and runs parallel to the westbound lanes of the parkway through the remainder of Washington, D.C. Past this, the Suitland Parkway curves east through woods and reaches a traffic light with Stanton Road SE. The road curves southeast and comes to

396-461: Is 100 km/h (summertime) and 80 km/h (wintertime). On motorways the speed limits are 120 and 100 km/h respectively. Especially during winter the speed limits can be changed due to weather conditions. A Kraftfahrstrasse ( German for "motor-power road", also colloquially called Schnellstraße , literally "fast road") in Germany is any road with access limited to motor vehicles with

440-594: Is 110 km/h (70 mph). Expressway road signs are white on blue. In Denmark , a 'motortrafikvej' ( Danish for "motor traffic road") is a high-speed highway with a speed limit between 80–90 km/h (50–56 mph). The most common 'motortrafikvej' has two lanes (1+1) or 2+1. There is no grade intersections. The signs for 'motortrafikvej' have white text on blue background. In Finland , highways are separated into three categories: all-access valtatie ("main road"), limited-access moottoriliikennetie ("motor traffic road") and finally moottoritie ("motorway");

484-734: Is 9.35 miles (15.05 km) long. Its eastern terminus is at Pennsylvania Avenue ( Maryland Route 4 ), just outside the Capital Beltway and near Joint Base Andrews . Its western terminus is at Interstate 295 and the northbound approach to the Frederick Douglass Memorial Bridge . The parkway was listed on the National Register of Historic Places in 1995. It is also part of the National Highway System . The eastern half

528-404: Is a public road, the beginning of which is indicated by the first signboard (F9) and the end by the second sign (F11). An important difference with an autosnelweg is that crossroads as well as traffic lights can be on an autoweg . In Belgium there is no specific speed regulation for an autoweg . Only motor vehicles and their trailers (with the exception of mopeds), agricultural vehicles and

572-487: Is accessed via cross roads or frontage roads , while minor roads can cross at grade and farms can have direct access. This definition is also used by some states, some of which also restrict freeways only to motor vehicles capable of maintaining a certain speed. Some other states use "controlled access" to mean a higher standard than "limited access", while others reverse the two terms. While Australia 's larger capital cities feature controlled-access highway networks,

616-643: Is between 50–70 km/h (31–43 mph) and in rural and desert areas between 90–110 km/h (56–68 mph). The term Expressway as used in English in Japan refers to both freeway -style highways and narrower, more winding, often undivided Regional High-Standard Highways 地域高規格道路 ( ちいきこうきかくどうろ ) . Both types of expressways have a combined length of 10,021 km (6,227 mi) as of April 2012. Limited-access roads in Malaysia usually, but not always, take

660-431: Is reduced to 110 km/h for vehicles under 3.5 tons, and 70 km/h for vehicles over 3.5 tons. In Hungary there are multiple types of dual carriageways. One part is almost identical with motorways, but the driving lanes are narrower. Parameters of a 2+2 lane dual carriageway off-habitat area: Parameters of a 2+2 lane dual carriageway in habitat (town/city) area: There are also semi-motorways with only one side of

704-515: Is usually provided by traffic lights or roundabouts . U-turns and any deliberate stopping are prohibited. Kraftfahrstraßen are out of bounds to pedestrians , except for special crosswalks. Expressways in Hungary are called Autóút (Auto/car road). They are mostly dual carriageways. The main difference between Hungarian motorways and expressways is, that they are more cheaply built with narrower width and often undivided. Maximum speed limit

748-591: The Anacostia station and the opening of the Branch Avenue , Congress Heights , Naylor Road and Southern Avenue stations. The station has an island platform located in an open cut northeast of the interchange between Suitland Parkway and Silver Hill Road . A parking garage is located east of the station. 38°50′38″N 76°55′54″W  /  38.84384°N 76.931607°W  / 38.84384; -76.931607 This article relating to

792-692: The Indian National Highway System on which they are the highest class of road. The National Highways Development Project is underway to add an additional 18,637 km (11,580 mi) of expressways to the network by the year 2023. Expressways in Iran are one class lower than freeways and are used in large urban areas such as Isfahan , Mashhad , or Tehran and between other important cities (Usually two province capitals) in rural and desert areas. The speed limit in Urban areas

836-663: The Naylor Road station on Washington Metro 's Green Line . Left turns are prohibited at the MD 637 intersection. A short distance later, the parkway comes to an interchange with MD 5 . Past this interchange, the Suitland Parkway continues east and passes under the Green Line, with the median widening as it continues southeast through woods. The median narrows again as the road comes to an interchange with MD 458 in Suitland near

880-411: The Suitland station on the Green Line. Past MD 458, the parkway median widens again and the road continues through woodland a short distance to the southwest of the Green Line. The road has an at-grade intersection with Meadowview Drive, which heads south into a residential development, before the subway line passes over the parkway to head south. The Suitland Parkway curves east and the median narrows as

924-575: The Washington Metropolitan Area Transit Authority (WMATA). The station is located at Silver Hill Road and Suitland Parkway, providing service for only the Green Line . Groundbreaking for the final segment of the Green Line occurred on September 23, 1995, and the station opened on January 13, 2001. Its opening coincided with the completion of approximately 6.5 miles (10.5 km) of rail southeast of

968-1077: The federal government . Notable examples of limited-access roads are the Federal Highway , Skudai Highway , Gelugor Highway , Kuantan Bypass and Kuching Bypass . Limited-access roads in Singapore are formally known as semi-expressways (in contrast to controlled-access highways which are known as expressways ). While still functioning as high-speed roads, semi-expressways may still have at-grade intersections with traffic lights , and speed limits are not uniform. Grade separation is, however, still typical at major junctions. Five roads have been designated as semi-expressways: Bukit Timah Road , Jurong Island Highway , Nicoll Highway , Outer Ring Road System and West Coast Highway . Motorways in South Korea (자동차 전용 도로, jadongcha jeonyong doro , literally 'motor vehicle-only road') include various grades of highways other than expressways . Contrary to

1012-546: The M31 Hume Highway between Sydney and Melbourne, are almost all limited-access highways. In spite of this, 'freeway' terminology is used on signage for most regional limited access highways in the state of Victoria . The terms Motorway and Expressway in New Zealand both encompass multi-lane divided freeways as well as narrower 2 to 4-lane undivided expressways with varying degrees of grade separation ;

1056-492: The country's motorways and are usually upgraded versions of the national highways. The total length of Pakistan's expressways is 260-kilometre (160 mi) as of November, 2016. Around 770-kilometre (480 mi) of expressways are currently under construction in different parts of country. Most of these expressways will be complete between 2017 and 2020. Expressways in India make up more than 5,579  km (3,467  mi ) of

1100-519: The difference being that in New Zealand a Motorway has certain additional legal traffic restrictions. The Expressway Network of the People's Republic of China is the longest highway system in the world. The network is also known as National Trunk Highway System (NTHS). By the end of 2016, the total length of China's expressway network reached 131,000 kilometers (82,000 mi). Expressways in China are

1144-528: The eastbound direction of the parkway via a ramp. At this point, the Suitland Parkway passes to the north of Joint Base Andrews and comes to an interchange that provides access to the north gate of the base. A short distance later, both MD 337 and the Suitland Parkway end at a traffic light with MD 4 in Forestville . Commercial vehicles, such as trucks, are allowed on the Washington, D.C. portion of

1188-500: The expressway in South Korea, the status of motorway is a measure of traffic control rather than a class of road. For example, Jayu-ro is a segment of national route 77 as well as a motorway. As of June 2011, 1,610 km of highways in total were designated as motorways. (1,052 km national highways, 351 km metropolitan highways, 185 km regional highways and 20 km municipal highways) Like on expressways, motorcycles are not permitted. Sri Lanka has ensured to classify

1232-427: The expressways in reference to the connotation of E grades. As of 2014 , three expressways namely the  E01   Southern Expressway ,  E02   Outer Circular Expressway and the  E03   Colombo – Katunayake Expressway have been created. A tax levying structure is proposed for travelling via the expressways. Speed limits in the range of 80–100 km/h is attested for travelling through

1276-708: The expressways. Up to now two expressways namely the Northern Expressway and the Ruwanpura Expressway are in process to satisfy the needs of public transport. [REDACTED] Expressways in Taiwan may be controlled-access highways similar to National Freeways or limited-access roads. Most have Provincial (as opposed to National) Highway status, although some are built and maintained by cities. All provincial expressways run east–west except for Provincial Highway No. 61 , which runs north–south along

1320-413: The lack of one or more required features. In absence of specific regulation signs, a type-C road is accessible by all vehicles and pedestrians, even if it has separate carriageways and no cross-traffic. Suitland station Suitland station is an island platformed Washington Metro station in Suitland, Maryland , United States . The station was opened on January 13, 2001, and is operated by

1364-469: The latter two are marked with green signage, while valtatie signage is blue. While most of the network is all-access road, 779 km (484 mi) of it is motorway, and 124 km (77 mi) is limited-access road. The access is limited to motor vehicles faster than 50 km/h, thus excluding pedestrian, bicycle, moped or tractor traffic; furthermore, towing is not allowed. Limited-access roads are generally similar to motorways, but do not fulfill all

1408-458: The motorway built. After the missing lanes are built, they will become standard motorways. A High-quality dual carriageway (HQDC) in Ireland is normally completed to a motorway standard, including no right-turns, but with no motorway restrictions. These are common on the final stretches of motorways nearing a major city, generally in order to enable use of bus stops and city bus services on

1452-401: The name highway ( Malay : lebuhraya – this is also the name for expressways ). Highways normally have a lower speed limit than expressways (but still higher than the rest of the local road network), and permit at-grade intersections and junctions to residential roads and shopfronts, although grade separation is still typical. Highways are normally toll-free and are owned and operated by

1496-593: The parkway, but must exit at Alabama Avenue. All exits are unnumbered. Limited-access road The first implementation of limited-access roadways in the United States was the Bronx River Parkway in New York , in 1907. The New York State Parkway System was constructed as a network of high-speed roads in and around New York City . The first limited access highway built is thought to be

1540-431: The particular stretch of road. Speed limits are normally 100 km/h compared to 120 km/h on motorways In Italy there are: Type B highway (or strada extraurbana principale ), commonly but unofficially known as superstrada , is a divided highway with at least two lanes for each direction, paved shoulder on the right, no cross-traffic and no at-grade intersections. Access restrictions on such highways are exactly

1584-895: The privately built Long Island Motor Parkway in Long Island , New York. The Southern State Parkway opened in 1927, while the Long Island Motor Parkway was closed in 1937 and replaced by the Northern State Parkway (opened in 1931) and the contiguous Grand Central Parkway (opened in 1936). In the United States , the national Manual on Uniform Traffic Control Devices (MUTCD) uses "full control of access" only for freeways . Expressways are defined as having "partial control of access" (or semi-controlled access ). This means that major roads typically use interchanges and commercial development

1628-433: The road comes to an interchange with Suitland Road. The road continues east through more woods with nearby development including the incorporated town of Morningside , with the median widening as the road comes to a traffic light with MD 337 . It is at this point that southbound MD 337 splits from the westbound Suitland Parkway. The parkway passes under I-95 / I-495 without an interchange before northbound MD 337 merges onto

1672-581: The same of Italian motorways ( autostrade ), as well as signage at the beginning and the end of the highway (with the only difference being the background color, blue instead of green). Speed limit on type-B road is 110 km/h (68 mph). Type C highway (or strada extraurbana secondaria ), a single carriageway with at least one lane for each direction and shoulders. It may have at-grade, at-level crossings with railways , roundabouts and traffic lights . This category contains also dual carriageways that can not be classified as type-B highways because of

1716-491: The smaller metropolitan areas mostly rely on limited-access highways for high-speed local traffic. In South Australia the terms "expressway" and "freeway" can be synonymous. The Southern and Northern Expressways are both controlled-access highways. However, perhaps confusingly, the Port River Expressway is a limited-access highway. Dual carriageways that connect capital cities and regional centres, such as

1760-430: The technical requirements, such as several lanes in one direction or separation of opposite directions. Limited-access roads are usually built because the local population density is too low to justify a motorway. Often space has been left during construction for an eventual upgrade to a motorway. Limited-access roads also function as feeder routes for motorways. The general speed limit on main roads and limited-access roads

1804-407: The towing of fairground vehicles, as well as four-wheelers (without passenger compartment), are allowed to drive on an autoweg . An autoweg can consist of two or more lanes. The driving directions can be separated by a roadmarking, or by a central reservation. If a public road ( autosnelweg , autoweg , weg ) consists of two or more lanes that are clearly separated from each other by a roadside or

1848-421: The west coast. Some provincial expressway routes are still under construction. In Austria the speed limit on a Schnellstraße is 100–130 km/h (62–81 mph). Schnellstraßen are very similar to Austrian Autobahnen (freeways/motorways); the chief difference is that they are more cheaply built with smaller curve radius, often undivided and have fewer bridges and tunnels. In Belgium an autoweg

1892-539: Was a two-lane limited-access road, and the western half a four-lane divided limited-access road. In the 1990s the eastern half was doubled in size to match the western half, with that work completed in 1996. Around the same time a 2-mile-long trail, the Suitland Parkway Trail, was constructed from Pomeroy Road to Southern Avenue. The Suitland Parkway begins at an interchange with I-295 and South Capitol Street in Washington, D.C. , heading southeast as

1936-575: Was built during World War II to provide a road connection between military facilities in the Washington, D.C. metropolitan area and is named after Suitland, Maryland . It fully opened on December 9, 1944 as the Camp Springs highway, so called because it connected Camp Springs (now Joint Base Andrews ) in Prince George's County with Bolling Air Force Base . However one lane of the highway was opened in mid-October 1944. The Suitland Parkway
