A diamond interchange is a common type of road junction, used where a controlled-access highway crosses a minor road.
The Western Bypass is a section of the N1 and the Johannesburg Ring Road located in the city of Johannesburg, South Africa. Known at the time as the Concrete Highway, the freeway was initially opened in 1975 as a route to avoid the city centre of Johannesburg and to provide access to the western areas of the Witwatersrand. From the south, the Western Bypass begins at the Diepkloof Interchange in Soweto, where it splits from the N12 freeway and ends at the Buccleuch Interchange, where it merges with the N3 Eastern Bypass, M1 South and N1 Ben Schoeman freeways.
The N1 is a national route in South Africa that runs from Cape Town through Bloemfontein, Johannesburg, Pretoria and Polokwane to Beit Bridge on the border with Zimbabwe. It forms the first section of the famed Cape to Cairo Road.
A concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers. When two roadways share the same right-of-way, it is sometimes called a common section or commons. Other terminology for a concurrency includes overlap, coincidence, duplex, triplex, multiplex, dual routing or triple routing.
A diverging diamond interchange (DDI), also called a double crossover diamond interchange (DCD), is a subset of diamond interchange in which the opposing directions of travel on the non-freeway road cross each other on either side of the interchange so that traffic crossing the freeway on the overpass or underpass is operating on the opposite driving side from that which is customary for the jurisdiction. The crossovers may employ one-side overpasses or be at-grade and controlled by traffic light.
The R21 / P157 is a major north–south provincial route in eastern Gauteng Province, South Africa. Built in the early 1970s, it remains one of two freeways linking Pretoria with Johannesburg, via the R24. As the eastern of the two freeways, it links the Pretoria city centre with OR Tambo International Airport, the N12 freeway, and Boksburg. Between the Solomon Mahlangu Drive on-ramp in Monument Park, Pretoria, and the N12 in Boksburg, the R21 / P157 is an 8 lane highway and motorway (freeway), with 4 lanes in each direction. It has off-ramps leading to Irene, Olifantsfontein, Benoni, and Kempton Park, including a partial offramp to Atlas Road. The route intersects the N1 Highway near Centurion, the R24 near the airport, the N12 and N17 in Boksburg, and the N3 near Vosloorus on the East Rand, where it ends. The section from the N12 to the N3 is not a freeway. As early as the 1970s there were proposals to extend the R21 / P157 freeway further south and the freeway may be linked with the current eastern terminus of the M2 in Germiston in future.
The R24 is a major East-West provincial route in the Gauteng and North West provinces that links OR Tambo International Airport with Rustenburg via Johannesburg, Krugersdorp and Magaliesburg. The process of renaming the streets and freeway that form the route from Krugersdorp eastward to OR Tambo International after anti-apartheid stalwart Albertina Sisulu was completed in 2013.
In the field of road transport, an interchange or a grade-separated junction 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 or a limited-access divided highway (expressway), though they are sometimes used at junctions between surface streets.
Highway 6, also known as the Trans-Israel Highway or Cross-Israel Highway, is a major electronic toll highway in Israel. Highway 6 is the first Israeli Build-Operate-Transfer road constructed, carried out mainly by the private sector in return for a concession to collect tolls on the highway for a given number of years. It is also one of the largest infrastructure projects undertaken in Israel.
Highway 1 is the main highway in Israel, connecting Tel Aviv and Jerusalem, and continuing eastwards to the Jordan Valley in the West Bank.
The N12 is a national route in South Africa which runs from George through Beaufort West, Kimberley, Klerksdorp and Johannesburg to eMalahleni.
Route 443 is also known as Ma'ale Beit Horon, following the ancient east-west trade route connecting the Via Maris and the Way of the Patriarchs. It is the main highway connecting Tel Aviv and Gush Dan with Jerusalem via Modi'in. While technically listed as a regional road, it is for the most part a divided, four-lane highway which utilises some grade separation and interchanges, as well as major at-grade intersections, and thus is not classified as a motorway, even though there is a short motorway section on its western end, connecting it to westbound Highway 1.
Highway 38 is an arterial road in the low plains of Judea in Israel. It serves as the main access route to Beit Shemesh and as a main north–south route in the region. Along the route are many nature preserves and archeological sites.
Hevel Modi'in Regional Council is a regional council in central Israel. It was founded in 1950 and covers an area from Petah Tikva to Modi'in.
Route 411, is the designation of a regional route in the Shephelah region in Israel running southeasterly consolidating previous local roads and new construction. The western section begins at Highway 42 near Kfar Gevirol in western Rehovot and continues just past Route 410. The central section, completed in June 2014, continues to the entrance of Kvutzat Shiller. The eastern section begins just short of Highway 40 south of Rehovot and terminates at Highway 3 towards Jerusalem, bypassing the towns of Kiryat Ekron and Mazkeret Batya.
Ben Shemen Interchange is a major freeway interchange complex in central Israel, connecting Highway 1, Highway 6, Route 443 and Route 444, as well as several local roads. The interchange is located near moshav Ben Shemen and Ben Shemen Forest, hence its name. It is one of the largest and most complex interchanges in the country.
The N14 is a national route in South Africa which runs from Springbok in the Northern Cape to Pretoria in Gauteng. It passes through Upington, Kuruman, Vryburg, Krugersdorp and Centurion. The section between Pretoria and Krugersdorp is maintained by the Gauteng Provincial government and is also designated the P158.
The N17 is a national route in South Africa which runs from Johannesburg to Oshoek (Ngwenya) on the border with Eswatini. It passes through Springs, Bethal and Ermelo.
The Ben Schoeman Freeway or Ben Schoeman Highway is the main freeway between Johannesburg and Pretoria, and consists of portions of the M1, N1, and N14. Opened in 1968, it is named after former Minister of Transport Ben Schoeman, and is undoubtedly the busiest road in South Africa.
