A two-lane expressway or two-lane freeway is an expressway or freeway with only one lane in each direction, and usually no median barrier . It may be built that way because of constraints, or may be intended for expansion once traffic volumes rise. The term super two is often used by roadgeeks for this type of road, but traffic engineers use that term for a high-quality surface road. Most of these roads are not tolled.
30-525: The Minō Toll Road (箕面有料道路 Minō Yūryōdōro ) is a two-lane toll road in Minoh, Osaka that connects the Shin-Meishin Expressway to the southern limits of the city via a tunnel under Mount Minō. The Minō Toll Road was opened to traffic on 30 May 2007 between its southern terminus at Osaka Route 9 and the northern terminus at the main line of Japan National Route 423 . On 10 December 2017
60-554: A four-lane expressway with at-grade intersections (labelled as an arterial road for political convenience), instead of six-lane freeway with grade-separations. The Metro Toronto government agreed to extend it farther south to St. Clair Avenue . Fresh from battling the Spadina Expressway, anti-Spadina groups started battling the extension and soon, Parkdale residents joined in the debate, fearing an extension would pass directly through their neighbourhood. Additionally,
90-782: A full expressway in 1997. While the full four-lane divided toll expressways are more favored in recent years due to their higher traffic capacity, a few two-lane expressways do exist, such as the Kempas Highway and the North Klang Straits Bypass . These expressways, however, only have partial access control with at-grade intersections commonly available like most other federal and state roads. Nevertheless, these two-lane highways are still classified as "two-lane expressways" as they are maintained by highway concessionaires, namely PLUS Expressways Berhad (Kempas Highway) and Shapadu (North Klang Straits Bypass). Meanwhile,
120-618: A land transfer in which the right-of-way for the Spadina Expressway south of Eglinton was given to the City of Toronto (which effectively blocked any southward extension of the Spadina Expressway) in exchange for Black Creek Drive being transferred to Metro. Had this not been done voluntarily then the province would have seized the Spadina right-of-way and billed Metro for the cost of Black Creek Drive. In 1989, Metro Toronto initiated
150-588: A southerly extension. Black Creek Drive officially transitions into Highway 400 at the Maple Leaf Drive overpass, southeast of the Jane Street interchange. The roadway is named after the Black Creek ravine, which it parallels for most of its route. It features a maximum speed limit of 70 km/h (43 mph). Following the path of a proposed freeway extension of Highway 400, it
180-542: A study of the extension of Black Creek Drive south to the Gardiner Expressway. The Canadian Automobile Association has noted that the route operates inefficiently in its present form as a super-4 expressway and advocated upgrading the route to a freeway, by utilizing the corridor's right-of-way to widen it to six lanes and reconstruct the at-grade intersections to interchanges. The following table lists intersections along Black Creek Drive. The entire route
210-569: A super-2 expressway is simply referred to as a super-2, regardless of whether it is fully controlled-access or not. Highway 410 in Ontario was originally a super-2 before being upgraded to a full freeway. Similarly, most of Highway 102 in Nova Scotia was a super-2 for three decades before being upgraded. Many super-2 expressways are simply just short transitional segments between surface street and four-lane divided freeways. A super-4 expressway
240-450: Is a high-speed surface road with at-grade intersections, depending on the common usage of the term expressway in the area. By this definition, Super-2s can be considered the first stage of project which is expected to become a full freeway, with the transportation authority owning the land necessary for the future adjacent carriageway. At-grade intersections exist but there is sufficient land to replace them with interchanges. In some US states,
270-572: Is a multi-lane divided highway with at-grade intersections, although the highway will become a full controlled-access freeway if the intersections are replaced with interchanges. A super-4 may have been a super-2 that has been twinned, although such instances of super-4 intermediaries are rare as super-2s are often upgraded right away to full freeways. Highway 40 in Ontario is a super-4 expressway between Highway 402 and Wellington St., and from Indian Rd to Rokeby Line. The remaining sections of Highway 40 are super-2 expressways. Other super-4 expressways include
300-763: Is separated at-grade from Queens Drive and Maple Leaf Drive, both of whom cross overhead. After Maple Leaf Drive overpass, the route becomes the provincial Highway 400 and thereafter falls under the control of the Ministry of Transportation of Ontario , including the interchange with Jane Street. South of Highway 401, all on-ramps to the southbound lanes of Highway 400 are signed as Black Creek Drive (without reference to Highway 400) even though Highway 400 continues until Maple Leaf Drive. The road has signalized intersections at Photography Drive, Eglinton Avenue West, Todd Bayliss Boulevard, Trethewey Drive and Lawrence Avenue West. From Trethewey north,
330-569: The Crosstown Expressway . A piece of a larger plan to expand a network of expressways across Toronto, the route was instead completed as a compromise between Metropolitan Toronto and the provincial government, as part of the larger Spadina Expressway controversy. The goal of Metro Toronto was to establish a network of expressways across and into Toronto, including the Crosstown Expressway north of Dupont Street, and
SECTION 10
#1732780824753360-848: The Hanlon Parkway in Guelph and Black Creek Drive in Toronto, both which have sufficient right of way to allow for interchanges and overpasses to replace the at-grade crossings. When a super-2 expressway is converted to a four-lane divided freeway, conversion artifacts such as double yellow lines, or broken yellow lines in passing zones are usually cleanly bestowed in favor of more consistent road marking for four-lane divided expressways. While most expressways in Japan are four-lane divided expressways with median barriers, some expressways in rural areas are two-lane expressways, such as some sections of
390-608: The Hokkaidō Expressway . The two-lane expressways in Japan are built in the same manner as the ordinary four-lane expressways with grade-separated interchanges and full access control, allowing future conversions to full four-lane divided expressways. The two-lane expressway is not a new concept in Malaysia , as the Kuala Lumpur–Karak Expressway was initially a two-lane toll expressway before being upgraded to
420-540: The Mount Dennis neighbourhood of Toronto. The four-lane road passes beneath railway tracks that carry the Kitchener GO Line and Union Pearson Express rail corridors. It travels north alongside Black Creek , from which it takes its name; Keelesdale Park lies to the east. The road continues north–northwest, intersecting Eglinton Avenue West . Coronation Park and Trethewey Park occupy the eastern side of
450-569: The Richview Expressway along Eglinton Avenue West. Plans were conceived to extend Highway 400 south from Highway 401 to Eglinton Avenue, where it would join those two new expressways. These plans would never reach fruition, as public opposition to urban expressways cancelled most highway construction in Toronto by 1971. The proposed route of the Highway 400 extension would have followed Weston Road as well as
480-799: The South Klang Valley Expressway at Teluk Panglima Garang is a two-lane carriageway making it the first true two-lane expressway in Klang Valley and the second in Malaysia. The first true two-lane expressway with full access control is the section of the Senai–Desaru Expressway between Cahaya Baru and Penawar. Some sections of two-lane freeway can be found on the N1 and the N2 highways. A portion of State Route 80 in
510-541: The United Nations Economic and Social Commission for Western Asia define an express road as a limited-access road that has signs reserving the roadway for specific categories of motor vehicles and that prohibits stopping and parking. Two-lane freeways are usually built as a temporary solution due to lack of funds, as an environmental compromise or as a way to overcome problems constrained from highway reconstruction when there are four lanes or more. If
540-635: The right-of-way of the Canadian Pacific Railway , then east along Dupont Street to connect with the Crosstown Expressway at present-day Christie Street . From there it would branch southward along Christie and Clinton Streets to the Gardiner Expressway. Alternate alignments included one following Parkside Drive south to the Gardiner, and one following the Canadian National Railway tracks south to Front Street and
570-403: The City of Toronto objected to the construction of the road south to St. Clair Avenue. A compromise was reached at Weston Road ; the 400 Extension would end there, but Weston Road would be widened to support the flow of traffic from Black Creek Drive. Construction began in late 1977. Black Creek Drive opened in 1982 from Jane Street south to Weston Road. On March 1, 1983, Metro Council performed
600-570: The Gardiner Expressway. The provincial government began construction of an extension of Highway 400 as far south as Jane Street in 1965, which was completed and opened on October 28, 1966, while the remainder of the plans were shelved following the cancellation of the Spadina Expressway in 1971. The provincial government still owned the right-of-way along the Black Creek Valley and agreed to construct it as
630-608: The Hanoi-Lao Cai Expressway is two-laned. The section between Cam Lo and Hoa Lien of the North-South expressway is two-laned. Black Creek Drive Black Creek Drive is a limited-access arterial road in Toronto , Ontario, Canada. A four-lane route that runs north–south, it connects Weston Road and Humber Boulevard with Highway 401 via Highway 400 , the latter of which it forms
SECTION 20
#1732780824753660-510: The concept of express road encompasses roads which are classified between a motorway and an ordinary road. It does not necessarily have two lanes. This concept is recognized both by European Union law and under the UNECE treaty. This type of road is not very standardized, and its geometry may vary from country to country or within a same country. These roads are usually, but not always, limited-access roads . Some European Union regulation considers
690-561: The high-quality roads to be roads "which play an important role in long-distance freight and passenger traffic, integrate the main urban and economic centres, interconnect with other transport modes and link mountainous, remote, landlocked and peripheral NUTS 2 regions to central regions of the Union". According to this same regulation "High-quality roads shall be specially designed and built for motor traffic, and shall be either motorways, express roads or conventional strategic roads." Eurostat and
720-446: The road is widened, the existing road is typically allocated to traffic going in one direction, and the lanes for the other direction are built as a whole new roadbed adjacent to the existing one. When upgraded in this manner, the road becomes a typical freeway. Many two-lane freeways are built so that when the road is upgraded to a proper divided freeway, the existing overpasses and ramps do not need reconstruction. A super-2 expressway
750-412: The road north of Eglinton, while the western side is occupied by commercial and industrial uses. Much of this land was a former Kodak plant, marked today only by the existence of Photography Drive. Between Trethewey Drive and Lawrence Avenue West , the road passes between residential subdivisions within the Black Creek ravine. North of Lawrence, the road diverges from the Black Creek ravine. The road
780-399: The section north of Eglinton Avenue fits the definition of a limited controlled-access expressway since bicycles and pedestrians are banned from using the roadway or paved shoulders. Black Creek Drive forms the southerly extension to Highway 400, and was originally intended as part of a proposed expressway that would have connected Highway 401 with the Gardiner Expressway, via
810-637: The toll road was connected to the Shin-Meishin Expressway at the northern terminus of the toll road in addition to the already built junction with National Route 423. The entire toll road is in Osaka Prefecture . Two-lane expressway A somewhat related concept is a "four-lane undivided freeway". This is much rarer; a current example is U.S. Route 101 in California through Humboldt Redwoods State Park . In Europe,
840-539: The two directions are separated by a 81 cm (32 inches) tall Jersey barrier , and north of Lawrence, the directions are separated by a set of steel guard rails. South of Trethewey, the two directions are separated by a grass median. The speed limit is 70 km/h (43 mph) for the route's entire length. Although the city classifies it as an arterial road (Google Maps also colour-codes it as an arterial unlike other expressways with at-grade crossings like Highway 7 (York Regional Road 7) between Vaughan and Richmond Hill ),
870-661: The vicinity of Bisbee is a two-lane expressway with an interchange at West Boulevard and Tombstone Canyon Road ( Historic US 80 ). A 1.8 mile section of the State Road 912 freeway in East Chicago, Indiana is 2 lanes. This 2-lane section includes a new bridge over the Indiana Harbor and Ship Canal that opened in 2020. The original bridge that was closed in 2009 and demolished in 2012 carried 6 lanes of traffic. The section from Yen Bai City to Lao Cai City of
900-663: Was built instead as an arterial road with at-grade intersections by the provincial government . While Metropolitan Toronto and the Province of Ontario sought to extend Highway 400 south to the Gardiner Expressway , public opposition to building freeways into central Toronto resulted in the road being constructed only as far south to Weston Road as a limited controlled-access expressway with at-grade intersections. At its south end, Black Creek Drive begins at an intersection with Weston Road and Humber Boulevard, in
