Grade or grading may refer to:
An intersection or an at-grade junction is an junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
The A1 is the longest numbered road in the UK, at 410 miles (660 km). It connects London, the capital of England, with Edinburgh, the capital of Scotland. It passes through or near North London, Hatfield, Welwyn Garden City, Stevenage, Baldock, Letchworth Garden City, Biggleswade, St Neots, Huntingdon, Peterborough, Stamford, Grantham, Newark-on-Trent, Retford, Doncaster, York, Pontefract, Wetherby, Ripon, Darlington, Durham, Sunderland, Gateshead, Newcastle upon Tyne, Morpeth, Alnwick and Berwick-upon-Tweed.
The A1 is a major route in Northern Ireland. It runs from Belfast via Lisburn and Banbridge to the border with the Republic of Ireland south of Newry, from where the road continues to Dublin, becoming the N1 road and M1 motorway. Between Sprucefield and Carrickcarnan the road forms part of the European route E01.
The N11 road is a national primary road in Ireland, running for 129 km (80 mi) along the east side of Ireland from Dublin to Wexford. It passes close to Bray, Greystones, Wicklow, Arklow, Gorey, and Enniscorthy. Beyond Wexford, the route continues to Rosslare as the N25. The road forms part of European route E01. As of July 2019 the N11/M11 is of dual carriageway or motorway standard from Dublin as far as Oilgate in County Wexford.
The A63 is a major road in Yorkshire, England between Leeds and Kingston upon Hull. A section between North Cave and Hull forms the eastward continuation of the M62 motorway and is part of the unsigned Euroroute E20.
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.
NOT even a list!
A dual carriageway or divided highway 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.
Spaghetti Junction is a nickname sometimes given to a complicated or massively intertwined road traffic interchange that is said to resemble a plate of spaghetti. Such interchanges may incorporate a variety of interchange design elements in order to maximize connectivity.
In civil engineering, 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.
A flying junction or flyover is a railway junction at which one or more diverging or converging tracks in a multiple-track route cross other tracks on the route by bridge to avoid conflict with other train movements. A more technical term is "grade-separated junction". A burrowing junction or dive-under occurs where the diverging line passes below the main line.
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.
The Red Cow interchange is a major road junction in west Dublin, Ireland on the M50, meeting the N7 Naas Road at a free-flow grade-separated junction which incorporates a tram line. The N7 route commences at this junction, junction 1 on the N7 and junction 9 on the M50, and the Naas Road from the city centre via Inchicore to the Red Cow interchange comprises part of the R110 and the R810. The junction is the busiest road junction in Ireland. Before a recent upgrade, it frequently had tailbacks several kilometres long on the routes leading to it.
A junction is where two or more roads meet.
The City of Peterborough in East Anglia has an extensive and well integrated road network, owing partly to its status as a new town. Since the 1960s, the city has seen considerable expansion and its various suburbs are linked by a system of parkways.
The A8 in Northern Ireland is a 26.1 km route connecting the city of Belfast with the harbour town of Larne. One of the busiest routes in the region, the road forms part of the unsigned European routes E01 and E18.
The A42 is a major trunk road in the East Midlands region of the United Kingdom. It links junction 23A of the M1 motorway to junction 11 of the M42 motorway. The A42 is in effect a continuation of the M42, and its junctions are numbered accordingly.
Grade II* listed buildings in Devon are listed buildings in the county of Devon, England, that are particularly important buildings of more than special interest. The county of Devon is divided into ten districts, namely Exeter, East Devon, Mid Devon, North Devon, Torridge, West Devon, South Hams, Teignbridge and the unitary authorities Plymouth and Torbay. As there are 1,237 Grade II* listed buildings in the county the list has been split into separate lists for each district.
Secondary Highway 500, commonly referred to as Highway 500, was a secondary highway in the Canadian province of Ontario which was first designated in 1956. It's route was renumbered in 1964, becoming:
