The Watford Ring Road is a road located in Watford, Hertfordshire, UK. It is numbered A411, and serves as a one way system around the town centre. It has decreased traffic through the town centre, and now provides links to every part of Watford, as well as the M1 motorway (by way of the A4008 road).
Watford is a town and borough in Hertfordshire, England, 15 miles (24 km) northwest of central London.
Hertfordshire is one of the home counties in England. It is bordered by Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it is placed in the East of England region.
The M1 motorway connects London to Leeds, where it joins the A1(M) near Aberford, to connect to Newcastle. It was the first inter-urban motorway to be completed in the UK; the first motorway in the country was the Preston By-pass, which later became part of the M6.
The ring road essentially acts as one big roundabout around the town centre, whilst also having bus stops and roads in towards the centre. There are numerous multi-storey car parks that can be reached from the ring road: Palace, Queens, Kings, Church, Gade and Sutton. These are connected to the Harlequin Shopping Centre and Watford Town Centre.
The Harlequin Shopping Centre, currently known as Intu Watford, is a shopping centre in the middle of Watford, Hertfordshire, United Kingdom. It opened between 1990 and 1992. The centre was rebranded as intu Watford in 2013 following the renaming of its parent Capital Shopping Centres Group as Intu Properties.
The road is a typical example of 1960s town planning: grade separation is used on three occasions to separate the traffic from pedestrians and cycles. The most notable of these is the large bridge which takes the road across Watford's High Street. Another example is the short branch from the ring road to the A412 road, which crosses an underpass before joining with the latter at a full-blown grade separated junction.
Grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges, tunnels, or a combination of both can be built at a junction to achieve the needed grade separation.
The A412 is a road in England between Slough and Watford. It was the main artery for this corridor and used to continue to St Albans prior to the construction of the M25. It provides interchange to the A4 in Slough, the A40/M40 at the Denham Roundabout, the M25 in Maple Cross, the A404 in Rickmansworth town centre, the A411 on a partially grade separated dual carriageway in Watford town centre, and the A41 in North Watford.
A roundabout is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.
Boulevard Périphérique, sometimes called Périph', is a controlled-access dual-carriageway ring road in Paris, France. With a few exceptions, it is situated along Paris's administrative limit.
The A41 is a major trunk road in England that links London and Birkenhead, although it has now in parts been superseded by motorways.

The road forms part of European route E01. As of 2015 the N11/M11 is of dual carriageway or motorway standard from Dublin as far as Gorey in County Wexford.
The A45 is a major road in England. It runs east from Birmingham past the National Exhibition Centre and the M42, then bypasses Coventry and Rugby, where it briefly merges with the M45 until it continues to Daventry. It then heads to Northampton and Wellingborough before running north of Rushden and Higham Ferrers and terminating at its junction with the A14 road in Thrapston.
The Leeds Inner Ring Road is part-motorway and part-A roads in Leeds, West Yorkshire, England, which forms a ring road around the city centre. It has six different road numbers that are all sections of longer roads. Clockwise, the roads are the A58(M), a motorway section of the A58 road; the A64(M), part of the A64 road; the A61 between York Road and the M621; the M621 between junctions 4 and 2; and the A643 between the M621 and A58.

A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, and partial controlled access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway, including limited or no access to adjacent property, some degree of separation of opposing traffic flow, use of grade separated interchanges to some extent, prohibition of some modes of transport such as bicycles or horses, and very few or no intersecting cross-streets. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.
The A4400 was a main road in Birmingham, United Kingdom that previously formed a ring around the city centre. Junctions on the road were largely grade separated, with pedestrians kept physically separate from vehicular traffic and most junctions allowing vehicles staying on the road to pass over or under those using the junction. It is now widely regarded as one of the classic urban planning blunders of the 20th century.

The R136 road is a regional road in Ireland, located in the southwest of Dublin. Named the Outer Ring Road, the route, which is dual carriageway, runs from the N4 at Lucan to the N81 at Tallaght, bypassing west of Clondalkin and crossing the N7 near Citywest. It was built as part of the planning for the new town of Adamstown.
A three-level diamond interchange is a type of highway interchange where through traffic on both main roads is grade-separated from intersections which handle transferring traffic. It is similar in design to a three-level stacked roundabout except for its use of conventional intersections, and can be thought of as two diamond interchanges fused together.
Ringway 4 was the outermost of the series of four London Ringways, ring roads planned in the 1960s to circle London at various distances from the city centre. They were part of a comprehensive scheme developed by the Greater London Council (GLC) to alleviate traffic congestion on the city's road system by providing high speed motorway-standard roads within the capital linking a series of radial roads taking traffic into and out of the city. Most of the scheme was cancelled in 1973.

Terminology related to road transport—the transport of passengers or goods on paved routes between places—is diverse, with variation between dialects of English. There may also be regional differences within a single country, and some terms differ based on the side of the road traffic drives on. This glossary is an alphabetical listing of road transport terms.
