116-407: A divided highway ( AmE ) 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 known as
174-428: A single carriageway regardless of how many lanes there are. Dual carriageways have improved road traffic safety over the years and over single carriageways and typically have higher speed limits as a result. In some places, express lanes and local or collector lanes are used within a local-express-lane system to provide more capacity and to smooth out traffic flows for longer-distance travel. A very early (perhaps
232-414: A broken line indicating passing zones and a solid line indicating no passing zones and solid white baseline shoulder stripes. On undivided roads with more than one lane in each direction, the center is normally marked with a double solid line. The double solid stripe denotes that it is illegal to pass on the other side of the center line. Multilane one-way carriageways use broken white lines between lanes;
290-478: A built up area is indicated by the presence of street lights; on lit dual carriageways that are not considered to be in a built-up area, the speed limit will be clarified with intermittent signs. Although in Ireland the term dual carriageway technically applies to any road with physically separated lanes, it is usually used only to refer to those route sections that do not have a motorway designation. Most often it
348-582: A central median, usually fitted with guardrails. The most heavily used expressways in Croatia is the D10 road , connecting capital Zagreb to Vrbovec and Križevci . In the United States, this type of road may be called a divided highway, boulevard, parkway, expressway, freeway, or interstate, and has a grassy median or Jersey barrier separating the traffic directions. With few exceptions, all roads in
406-484: A freeway from the 1950s to 1970s. Opened to traffic in 1940, the 160-mile-long (260 km) Pennsylvania Turnpike was the first rural dual carriageway built in the United States. By 1955 several states had built dual carriageway freeways and turnpikes and in 1957 the Interstate Highway System began. Completed in 1994, the major highway system links all the major cities of the United States. In
464-467: A lack of funding elsewhere, partial controlled-access "expressways" and limited-mobility divided arterial roads are more common in the western provinces where there are no specially numbered systems of freeways. On some portions of Ontario 's 400-series highway network, the median may be either steel guardrail or an Ontario tall-wall barrier rather than an unpaved strip, particularly in urban areas. Some partial limited-access divided highways such as
522-502: A median barrier preventing left turns (motorists have to use a "turnabout" overpass to access exits on the opposing direction). Speed limits in Canada are usually 80 to 90 km/h on signalized divided highways and 100 to 120 km/h on freeways. In Australia, dual carriageways are referred to in some regions as divided roads, though there is no official terminology. Each state's road agency has its own definition of what constitutes
580-501: A narrow strip of trees down the middle. In 1907 the Long Island Motor Parkway opened, and roughly 20% of it featured a semi-dual-carriageway design. The New York City Belt Parkway system, which was built between 1907 and 1934, also pioneered the same design. However the majority of it featured concrete or brick railings as lane dividers instead of grass medians. In the year of 1924 the first Italian autostrada
638-605: A new standard was set to designate certain high-quality routes formally as "Expressways". Many roads such as the A1 , the A14 , the A19 and the A42 are built to a high quality, with grade-separated junctions, full barriers at roadside and central reservations and, in some cases, three lanes of traffic. They may still fall short of motorway standard in terms of hard shoulders, the height of overpasses or

#1732765857042696-500: A precedent for future highways. Although it, like the first autostrada , did not feature a dual-carriageway design, it inspired the mass construction of future high-speed roadways. During the 1930s, Germany, Italy, and the Soviet Union began construction of a network of dual carriageway expressways. By 1942, Germany had over 3,200 km (2,000 mi) of dual carriageway roads, Italy had nearly 1,300 km (810 mi), and

Some are heavy concrete obstructions which can bounce a vehicle back into the path of other traffic; others are made from steel ropes mounted on moderately weak posts, where the rope cuts into the vehicle body to slow the vehicle while keeping it against
812-510: Is autovía (literally autoway ). All of them are government-owned and not tolled. First-generation autovías, built in the 1980s and early 1990s, were just duplications in parallel of existing roads, as shown in the photograph. Modern autovías are two carriageways built from scratch, leaving the old road they replace as an alternative route for pedestrians, bicycles and other non-motorized vehicles. Private properties may have direct access to an autovía, as well as bus stops and gas stations in
870-399: Is national roads (roads with a route number prefix of N ; e.g. N8 ) that are built as or upgraded to dual carriageway. A number of non-national roads (for example, regional roads ) are dual carriageway, for example in urban areas near or in cities, or where the road was part of a national route. Dual carriageways of this class differ from motorways in a number of ways. The hard shoulder
928-450: Is demarcated with a dashed yellow line (as opposed to an unbroken yellow line on motorways). The standard speed limit of 100 km/h (62 mph) for national routes usually applies (by default the limit is 80 km/h (50 mph) for non-national roads, even if dual carriageway). Local authorities have the power to apply a limit of up to 120 km/h (75 mph) as used on most motorways (The High Quality Dual Carriageway section of

Italian Highway Code ( Codice della strada ) divides dual carriageways into three different classifications: Italian type-B and type-C roads do not follow a specific numbering criterion. They may be numbered as Strade Statali (SS; "state roads"), Strade Regionali (SR; "regional roads"), Strade Provinciali (SP; "provincial roads") or Strade Comunali (SC; "municipal roads"). The Spanish word for dual carriageway

What may have been the world's first long-distance intercity dual carriageway/freeway was the Queen Elizabeth Way in Southern Ontario in Canada, initially linking the large cities of Toronto and Hamilton together by 1939, with construction on this stretch of the present-day Queen Elizabeth Way beginning in 1936 as "Middle Road". It was gradually upgraded to
1798-659: The UK, although the term "dual carriageway" applies to any road with physically separated lanes, it is frequently used as a descriptive term for major routes built in this style. Such major dual carriageways usually have two lanes of traffic in each direction, with the lane nearest the centre being reserved for overtaking. Occasionally dual carriageways have only one lane in each direction, or more than two lanes each way (sometimes to permit easier overtaking of slower uphill traffic). Different speed limits apply on dual carriageway sections from those that apply on single carriageway sections of

1856-428: The barrier until it has stopped. Often on urban dual carriageways where the road has been converted from a four-lane single carriageway the central reservation will not be substantial: often just a small steel divider to save space. Turning right (that is, across the line of traffic heading in the opposite direction) is usually permitted only at specific locations. Often the driver will be required to turn left (away from
1914-459: The basis of their structure these roads have, comparable to the German autobahn , the legal foundation that no default speed limit exists (design speed 130 km/h), although the standard advisory speed limit ( German : Richtgeschwindigkeit ) still exists. Nevertheless, expressways are often given speed limit signs. Exit signs. At the moment some (blue) motorways have been taken out of

Crash barriers are now mandatory for such routes, and wire cabling or full crash barriers (depending on whether or not the route is a motorway, and median width) have been fitted to existing routes. Between 2000 and 2010, three major types of dual carriageway were built on national road schemes in Ireland: In Germany the term Autobahnähnliche Straße (motorway-like road) refers to roads that are similar to German autobahn in grade-separation and signage. Most of them are designated as Kraftfahrstraßen (expressways), which means that

Roundabouts on dual carriageways are relatively common, especially in cities or where the cost of a grade-separated junction would be prohibitive. Where space is even more limited, intersections may be controlled by traffic lights. Smaller residential roads adjoining urban dual carriageways may be blocked off at one end to limit
2088-607: The entire length featured a dual-carriageway design. In the early 1930s, it was extended southward all the way to Naples and northward to Florence. Most of the original routing was destroyed by the Allies in World War II. By 1930 several US and European cities had built dual-carriageway highways, mostly to control traffic jams and/or to provide bypass routes for traffic. In 1932 the first German autobahn opened between Cologne and Bonn. It ran 21 km (13 mi) and became
2146-667: The federally funded Interstate Highway System are fully controlled access divided highways known as freeways . A broader definition, expressways , includes both freeways and partial limited-access divided highways, and "expressway" is often used specifically to refer to the latter. United States Numbered Highways , state highways and other locally maintained highways may also be divided. Speed limits on rural divided highways range from 65 to 75 miles per hour (105 to 121 km/h), with some portions as high as 80 miles per hour (130 km/h). One privately run toll road in Texas, SH 130, has

Dual carriageways or expressways in Croatia (Croatian: brza cesta ) are non- tolled roads with 2 or more lanes in each direction, but without emergency lanes . The main motorways in Croatia are also dual carriageways, but they have emergency lanes and tolls. Many bypasses and beltways of smaller cities in Croatia have been recently constructed or planned as dual carriageways. All dual carriageways in Croatia house

The two major accesses to Spain from France, AP-7 into Catalonia and AP-8 into the Basque Country , are autopistas. In comparison, the prime road between Spain and Portugal is the photographed autovía A-5 . In both autopistas and autovías,

Urban divided highways which are at grade and typically have much lower speed limits are sometimes called boulevards . In keeping with the U.S. Department of Transportation 's Manual on Uniform Traffic Control Devices (MUTCD), since the early 1970s all divided highways are striped by color to show the direction of traffic flow. Two-way undivided roads have an amber center line, with

2436-680: The introduction the Irish Planning system in 1964. Today Irish planning policy prohibits such development on National Primary or National Secondary roads where the speed limit exceeds 60 km/h (37 mph). This policy results from concerns expressed by the National Roads Authority. A local authority is not obliged to implement this policy and can disregard this policy at its own discretion. This would usually only occur in exceptional circumstances or where planners are overruled by elected councillors using section 140 of
2494-708: The lanes of an existing road (for example US Highway 33 between Elkhart and Goshen in northern Indiana). Like other countries, there are several types of divided highways; fully controlled-access divided routes with interchanges (commonly known as "freeways" in the United States, Australia, and regionally within Canada), expressways that often include a mix of interchanges and traffic signals, and divided arterial roads that are almost entirely stop-controlled. Unlike some other countries, divided dual carriageways in Canada are seldom equipped with traffic circles , roundabouts, or rotaries as alternatives to stoplights. In Canada,
2552-535: The median-side baseline is solid amber, and the right sideline is solid white. Frequently in the U.S. the two carriageways are separated by some distance (wide medians with small forests or even hills in them), but drivers can always tell whether the roadway is two-way or one-way—and, if one-way, the direction in which the traffic flows—by looking at the striping coloration. For an example, see inset showing U.S. Route 52 near Lafayette, Indiana . Some divided highways have been turned into undivided highways by widening
2610-678: The need to preserve access to adjoining property or to the absence of a non-motorway alternative route. Also, dual carriageways that are not motorway classified do not need to be equipped with emergency phones. Motorway restrictions only apply to motorway sections, rather than all dual carriageway sections of national roads (these are signposted with the N prefix on the route number, rather than M ). Some national secondary roads , and regional roads in particular often have houses, schools and other developments fronting on to them. Less important national primary roads , and older sections not yet upgraded may also feature such developments built before
2668-522: The number of junctions on the dual carriageway; often other roads will pass over or under the dual carriageway without an intersection. A dual carriageway with grade-separated junctions and which meets other requirements may be upgraded to motorway standard, denoted by an (M) added after the road number (e.g. " A1(M) " or " A38(M) "). Unlike in Ireland, there was no official terminology for 'high-quality dual carriageways' until April 2015, when in England
2726-453: The quality of intersecting junctions. The national speed limit applies on dual carriageways (unless it is in a ' built-up area ', or a lower limit is posted), which is as follows: A dual carriageway in a built up area will have a statutory speed limit of 30 mph (48 km/h) unless otherwise sign-posted. It is common for such urban dual carriageways to have an increased speed limit of 40 mph (64 km/h). A road deemed to be in

The road then reaches the main market street in Chipping Norton before entering the Cotswolds . The road here has many hills and turns, and is single-carriageway with some tight bends, with not much opportunity for overtaking. The road then enters Gloucestershire , and
2900-508: The roads allow higher speed traffic than is common on other roads. This in turn requires them to have dual carriageways in most cases. An exception is the 2+1 road system in some rural areas; these roads are also referred to as expressways. Autobahnähnliche Straßen mostly are colloquially referred to as gelbe Autobahn (yellow motorway) because they have the same technical standard as the Autobahn but have black on yellow signs instead of
2958-403: The same class of road, except in cities and built-up areas where the dual carriageway is more of a safety measure. When first constructed, many dual carriageways—including the first motorways—had no crash- or other barriers in the central reservation. In the event of congestion, or if a driver missed their exit, some drivers made U-turns onto the opposite carriageway; many accidents were caused as

The road begins at a roundabout junction with the A40 road on the northern section of Oxford's ring road in Oxfordshire . It has a grade separated junction with the A34 road (leading to the M40 motorway and Winchester ). From here,
3074-646: The term "divided highway" is used for this type of road, and the segment between the roadways is referred to as a "median". There may be gaps in the median strip of a partially controlled-access road to allow turning and crossing. More informally, a divided highway may be referred to as "twinned". This stems from the practice of "twinning" an existing two-lane highway and converting it into a divided highway. Such highways in southern Ontario, southern Quebec, and parts of Atlantic Canada usually feature full controlled-access with interchanges where robust federal and provincial funding has made such freeways possible. However, due to
