The M50 motorway is a C-shaped orbital motorway in Dublin and the busiest motorway in Ireland. The current route was built in various sections over the course of 27 years, from 1983 to 2010. It begins at Dublin Port, running northward through the Dublin Port Tunnel and along a portion of the Airport Motorway. It then turns west at its junction with the M1, circling the northern, western and southern suburbs of Dublin, before merging with the M11 at Shankill in South East Dublin. The road forms part of European route E01.
State Highway 1 is the longest and most significant road in the New Zealand road network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island.
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.
State Route 3 is a 120.67-mile-long (194.20 km) state highway located in southern Maine. It is a major interregional highway, connecting the Interstate 95 corridor to the Atlantic coast. The western terminus is at SR 8, SR 11 and SR 27 in Augusta and the eastern terminus is at SR 102 and SR 198 in Mount Desert. Major cities and towns along the length of SR 3 include Augusta, Belfast, Ellsworth, and Bar Harbor.
State Highway 20 (SH 20), also known as the Southwestern Motorway, is a New Zealand state highway linking State Highway 1 at Manukau with State Highway 16 in Point Chevalier, via Māngere and Onehunga. Along with its spurs, State Highway 20A and 20B, the state highway serves Auckland Airport, the country's largest, therefore making SH 20 a key arterial route connecting the airport to the wider Auckland region and most of the upper North Island. The route also forms the southern part of the Western Ring Route, a 48 kilometres (30 mi) motorway route bypassing central Auckland.
Dorset is a county in South West England. The county is largely rural and therefore does not have a dense transport network, and is one of the few English counties without a motorway. Owing to its position on the English Channel coast, and its natural sheltered harbours, it has a maritime history, though lack of inland transport routes has led to the decline of its ports.
State Highway 2 runs north–south through eastern parts of the North Island of New Zealand from the outskirts of Auckland to Wellington. It runs through Tauranga, Gisborne, Napier, Hastings and Masterton. It is the second-longest highway in the North Island, after State Highway 1, which runs the length of both of the country's main islands.
The Christchurch Southern Motorway is the main southern route into and out of Christchurch, New Zealand. The motorway forms part of State Highway 1 and State Highway 76.
The Christchurch–Lyttelton Motorway, also known as Tunnel Road, is part of the road network connecting Christchurch, New Zealand with its port at Lyttelton. It is part of State Highway 74.
The Christchurch Northern Motorway is the main northern route into and out of Christchurch, New Zealand. The motorway forms part of State Highway 1 and State Highway 74.
State Highway 73 is a major east-west South Island state highway in New Zealand connecting Christchurch on the east coast with Cass/Hokitika via the Southern Alps. It is mostly two lane, with some single-lane bridges north of Springfield but is mostly dual carriageway in Christchurch. The fourth and fifth-highest points of New Zealand's state highway network are on this road at Porters Pass and Arthur's Pass respectively.
Several special routes of U.S. Route 74 exist. In order from west to east they are as follows.
The North–South Corridor is a series of component motorways travelling through Adelaide, South Australia that will eventually form a continuous link from Old Noarlunga in the outer southern metropolitan Adelaide suburbs through to Gawler in northern metropolitan Adelaide, comprising a distance of 78km. Under South Australia's road route system, the corridor is signed as route M2.
The Western Belfast Bypass is an approximately five-kilometre-long (3.1 mi), four lane, grade separated motorway recently built to bypass the northern Christchurch suburb of Belfast, New Zealand. It is estimated that its construction will result in 17,000 fewer vehicles using Main North Road through Belfast, and shorten travel times between the north and west of Christchurch. In addition, the motorway will allow for improved public transport, cycling, and pedestrian options on Main North Road. It is expected that 21,500 vehicles per day will use the WBB motorway by 2026. The speed limit along the route is 100 km/h.
State Highway 76 (SH 76) is a state highway in Christchurch, New Zealand. This highway was gazetted in 2012 after stage 1 of the Christchurch Southern Motorway was completed. Beforehand, much of SH 76 was part of SH 73 and included the former two-lane Christchurch Arterial Motorway, which was upgraded to four lanes. SH 76 includes the entire length of the Christchurch Southern Motorway and forms the most direct route from the south of Christchurch to the city centre and Lyttelton.
The Western Corridor is a road in Christchurch, New Zealand which connects the suburb of Belfast, New Zealand, in the north to Hornby in the south and connects the Canterbury region to Christchurch Airport. Most of the traffic on the corridor heads to the city, the airport, Belfast or Hornby, while 15% of traffic travels further north or south.
U.S. Route 74 Alternate is an alternate route of U.S. Route 74 in Western North Carolina, running from the town of Forest City to the city of Asheville. It replaced US 74's former mainline route in 1994, when its parent highway was moved onto a new freeway alignment running from Forest City to I-26 in Columbus, North Carolina, and from there to I-40 and US 23 in Enka, North Carolina. Its alignment, a narrow, winding road, greatly differs from US 74 today, straying from its parent route by as much as ~14 miles, separated by as much as half an hour of driving time. Throughout its routing, it is in Buncombe, Henderson, and Rutherford counties.
