36-510: Maryland Route 168 ( MD 168 ) is a state highway in the U.S. state of Maryland . Known as Nursery Road , the highway runs 1.28 miles (2.06 km) from Hammonds Ferry Road in Linthicum east to MD 648 in Pumphrey in northern Anne Arundel County . MD 168 was built in the late 1920s. MD 168 begins at an intersection with Hammonds Ferry Road in a mixed commercial and industrial area at

72-539: A business district near Baltimore/Washington International Thurgood Marshall Airport . MD 168 heads east as a two-lane undivided road that passes underneath I-695 and intersects Fairview Avenue, which is unsigned MD 969A and provides access to westbound I-695. The state highway enters a residential area after it crosses MD 295. MD 168 reaches its eastern terminus at its junction with MD 648 (Baltimore–Annapolis Boulevard) in Pumphrey. Nursery Road continues east into

108-512: A designated National Highway System , but the system is completely unsigned, aside from the Trans-Canada routes. This makes Canada unique in that national highway designations are generally secondary to subnational routes. In Germany , state roads ( Landesstraßen or Staatsstraßen ) are a road class which is ranking below the federal road network ( Bundesstraßen ). The responsibility for road planning, construction and maintenance

144-492: A gap in the network. The "intermodal" and "anomaly" classes are not distinct designations, however, but simply represent an additional clarification of why the road holds "core" or "feeder" status. Since 2016, the "anomaly" category has been dropped and the road is simply included in the specific list. The tables below do not include "intermodal" municipal streets which connect major highways to intermodal facilities. Note that some highways listed here may be designated as part of

180-530: A population of at least 10,000 inhabitants are urban roads (type D and E) under the jurisdiction of the relevant municipalities. The state highway that cross towns or villages with a population of less than 10,000 inhabitants are urban roads (type D and E) under the jurisdiction of the municipality, subject to authorization from ANAS . State highways in India are numbered highways that are laid and maintained by state governments . Mexico 's State Highway System

216-523: A state or province include both nationally numbered highways and un-numbered state highways. Depending on the state, "state highway" may be used for one meaning and "state road" or "state route" for the other. In some countries such as New Zealand , the word "state" is used in its sense of a sovereign state or country. By this meaning a state highway is a road maintained and numbered by the national government rather than local authorities. Australia 's important urban and inter-regional routes not covered by

252-483: A strategic transport network of highways and freeways . The system includes but is not limited to the Trans-Canada Highway , and currently consists of 38,098 kilometres (23,673 mi) of roadway designated under one of three classes: Core Routes, Feeder Routes, and Northern and Remote Routes. The Government of Canada maintains very little power or authority over the maintenance or expansion of

288-617: A three-digit number designation, preceded by D . Provincial roads ( Turkish : İl yolu ) are secondary roads, maintained by respective local governments with the support of the KGM. The roads have a four-digit numbering grouped as two pairs, pairs are separated by a dash. First pair represents the license number of that province . State highways are generally a mixture of primary and secondary roads, although some are freeways (for example, State Route 99 in California, which links many of

324-503: A truly comprehensive expansion plan. In many parts of the country, the system relies on two-lane highways, or expressways which are not fully up to international freeway standards; according to Lakehead University economics professor Livio di Matteo, many parts of the system, even on the main Trans-Canada Highway portion of the network, still leave "the nation's east-west flow of personal and commercial traffic subject to

360-750: Is 100 km/h, with reductions when one passes through a densely populated area. The highways in New Zealand are all state highways, and the network consists of SH 1 running the length of both main islands, SH 2–5 and 10–58 in the North Island, and SH 6–8 and 60–99 in the South Island. National and provincial highways are numbered approximately north to south. State Highway 1 runs the length of both islands. Local highways ( Korean :  지방도 ; Hanja :  地方道 ; RR :  Jibangdo ; MR :  Chipangdo ) are

396-490: Is a system of urban and state routes constructed and maintained by each Mexican state. The main purpose of the state networks is to serve as a feeder system to the federal highway system. All states except the Federal District operate a road network. Each state marks these routes with a white shield containing the abbreviated name of the state plus the route number. New Zealand state highways are national highways –

432-521: Is divided into states and has state highways. For example, the longest highway in the state of São Paulo , the Rodovia Raposo Tavares , is designated as SP-270 and SP-295 . Canada is divided into provinces and territories, each of which maintains its own system of provincial or territorial highways, which form the majority of the country's highway network. There is also the national transcontinental Trans-Canada Highway system, which

468-451: Is free to choose a different marker, and most states have. States may choose a design theme relevant to its state (such as an outline of the state itself) to distinguish state route markers from interstate, county, or municipal route markers. National Highway System (Canada) The National Highway System ( French : Réseau routier national ) in Canada is a federal designation for

504-533: Is marked by distinct signs, but has no uniform numeric designation across the country. In the eastern provinces, for instance, an unnumbered (though sometimes with a named route branch) Trans-Canada route marker is co-signed with a numbered provincial sign, with the provincial route often continuing alone outside the Trans-Canada Highway section. However, in the western provinces, the two parallel Trans-Canada routes are consistently numbered with Trans-Canada route markers; as Highways 1 and 16 respectively. Canada also has

540-568: Is not a road class. The Strade Statali , abbreviated SS, is the Italian national network of state highways. The total length for the network is about 25.000 km (15.534 mi). The Italian state highway network are maintained by ANAS . From 1928 until 1946 state highways were maintained by Azienda Autonoma Statale della Strada (AASS). The next level of roads below Strada Statali is Strada Regionale ("regional roads"). The routes of some state highways derive from ancient Roman roads , such as

576-406: Is vested in the federal states of Germany. Most federal states use the term Landesstraße (marked with 'L'), while for historical reasons Saxony and Bavaria use the term Staatsstraße (marked with 'S'). The appearance of the shields differs from state to state. The term Land-es-straße should not be confused with Landstraße , which describes every road outside built-up areas and

612-626: The Strada statale 7 Via Appia , which broadly follows the route of the Roman road of the same name . Other examples are the Strada statale 1 Via Aurelia ( Via Aurelia ) and the Strada statale 4 Via Salaria ( Via Salaria ). Since the reforms following the birth of the Kingdom of Italy in 1861, the State took charge of the construction and maintenance of a primary network of roads for connections between

648-796: The 2000s accessed federal funding under the Strategic Highway Infrastructure Program. There is no single, ongoing program for federal contributions to the National Highway System; rather, these contributions have been made through a variety of separate infrastructure investment programs of defined length and scope. Recent transportation planning proposals have identified public-private partnerships and dedicated fuel taxes as possible mechanisms for providing more stable funding, although no comprehensive program has been implemented to date. The National Highway System has been criticized for lacking

684-488: The National Highway System may also incorporate city arterial streets to connect highway routes which are part of the system but do not directly interconnect, or to link the system to an important intermodal transport hub—such as a shipping port , a railway terminal , an airport or a ferry terminal —which is not directly on a provincial-class highway. Routes within the system continue to be maintained, funded and signed as provincial, rather than federal, highways. However,

720-1061: The National Highway System over only a portion of their total length, rather than over the whole highway. Termini listed below are those of a highway's NHS designation only, and may not necessarily always correspond to the termini of the highway as a whole. The system includes 4,478 kilometres (2,783 mi) of highway in Alberta . The system includes 7,040 kilometres (4,370 mi) of highway in British Columbia . The system includes 2,095 kilometres (1,302 mi) of highway in Manitoba . The system includes 1,802 kilometres (1,120 mi) of highway in New Brunswick . The system includes 2,467 kilometres (1,533 mi) of highway in Newfoundland and Labrador . The system includes 1,423 kilometres (884 mi) of highway in

756-576: The National Highway or National Route systems are marked under the State Route system. They can be recognised by blue shield markers. They were practically adopted in all states by the end of the 1980s, and in some states, some less important National Routes were downgraded to State Routes. Each state has or had its own numbering scheme, but do not duplicate National Route numbers in the same state, or nearby routes in another state. As with

792-475: The National Routes and National Highways, State Routes are being phased out in most states and territories in favour of alphanumeric routes. However, despite the fact that Victoria has fully adopted alphanumeric routes in regional areas, state route numbers are still used extensively within the city of Melbourne as a part of its Metropolitan Route Numbering Scheme . Brazil is another country that

828-708: The United States rather than on Canadian highways; even though the distance may be longer than the Trans-Canada Highway route, as it frequently takes a shorter amount of time due to the US Interstate system's higher speed limits, increased lane capacity, higher number of alternative routes, and reduced likelihood of being delayed by a road accident. In its current form, the National Highway System includes routes in all Canadian provinces and territories except Nunavut , which has no conventional road connections to any other Canadian province or territory. Officially

864-644: The cities of the Central Valley , Route 128 in Massachusetts, or parts of Route 101 in New Hampshire). Each state has its own system for numbering and its own marker. The default marker is a white circle containing a black sans serif number (often inscribed in a black square or slightly rounded square), according to the Manual on Uniform Traffic Control Devices (MUTCD). However each state

900-531: The federal government provides some funding assistance for important maintenance and expansion projects on designated highways through cost sharing programs. For instance, several recent maintenance projects on National Highway System routes in Saskatchewan were partly funded under the federal government's Building Canada Fund–Major Infrastructure Component, while several four-laning projects in Ontario in

936-541: The main cities; in 1865 the Lanza law introduced the classification of roads between national, provincial and municipal (see Annex F, art.10) and the Royal Decree of 17 November 1865, n. 2633 listed the first 38 national roads. Italian state highways are identified by a number and a name. In road signs and maps the number is preceded by the acronym SS, an acronym for strada statale ("state road"). The nomenclature of

972-482: The next important roads under the National highways . The number has two, three, or four digits. Highways with two-digit numbers routes are called State-funded local highways. State roads ( Turkish : Devlet yolu ) are primary roads, mostly under the responsibility of General Directorate of Highways (KGM) except in metropolitan city centers where the responsibility falls into the local government. The roads have

1008-487: The northern end of the unincorporated community of Linthicum. Access between MD 168 and eastbound Interstate 695 (I-695, Baltimore Beltway) is via the county highway between the state highway and the Patapsco River to the north. The west leg of the intersection is county-maintained West Nursery Road, which curves to the south, has a diamond interchange with MD 295 (Baltimore–Washington Parkway), and serves

1044-596: The parking lot for the Nursery Road station of MTA Maryland 's Baltimore Light RailLink . MD 168 was paved in concrete in 1929 from Hammonds Ferry Road—which was built contemporaneously and was designated MD 167 —to the Baltimore–;Annapolis Boulevard, which was then part of MD 3 . The entire route is in Anne Arundel County . State highway Roads maintained by

1080-640: The state highways managed by ANAS generally follows the SS n scheme, where n is a number ranging from 1 ( Aurelia ) up to 700 (of the Royal Palace of Caserta ) depending on the date of establishment of the state highway. Newly built ANAS roads, not yet classified, are identified by the acronym NSA, an acronym for nuova strada ANAS ("new ANAS road"). State highways can be technically defined as main extra-urban roads (type B road) or as secondary extra-urban roads (type C road). State highways that cross towns with

1116-655: The system beyond sharing part of the cost of economically significant projects within the network. Highways within the system are not given any special signage, except where they are part of a Trans-Canada Highway route. The system was first designated in 1988 by the Federal/Provincial/Territorial Council of Ministers Responsible for Transportation and Highway Safety, a council consisting of the federal, provincial and territorial Ministers of Transport . A total of 24,500 kilometres (15,200 mi) of highway were originally designated as part of

1152-405: The system maintains three classifications of road: Core, Feeder and Northern/Remote. Within the core and feeder classes, the system's official register made additional distinctions between conventional core or feeder routes and intermodal links or "anomalies", where a highway that does not meet the normal criteria for inclusion, or a municipal arterial road, has been adopted into the system to fill in

1188-498: The system. Highways selected for the system were existing primary routes that supported interprovincial and international trade and travel, by connecting major population or commercial centres with each other, with major border crossings on the Canada–United States border , or with other transport hubs. The system was further expanded in 2004, with the addition of approximately 14,000 kilometres (8,700 mi) of highway that

1224-547: The whims of an errant moose". American transportation planning academic Wendell Cox has also identified improvements to the system, so that Canada would have a comprehensive national freeway network comparable to the American Interstate Highway System , as an economically critical project for the country to undertake in the 21st century. Cox notes that many Canadians prefer to drive between Western Canada and Eastern Canada by travelling through

1260-530: The word "state" in this sense means "government" or "public" (as in state housing and state schools ), not a division of a country. New Zealand's state highway system is a nationwide network of roads covering the North Island and the South Island . As of 2006, just under 100 roads have a "State Highway" designation. The NZ Transport Agency administers them. The speed limit for most state highways

1296-409: Was not part of the original 1988 network. It was in this era that the current "core", "feeder" and "northern or remote" classes of route were established. Not all highways within the system are designated in their entirety, but may instead be part of the system over only part of their length; a few highways even have two or more discontinuous segments designated as part of the system. In some locations,
