An Expressway is an official term used by the Department for Transport and Highways England to describe Dual Carriageway Trunk Roads that are mostly grade separated, mostly dual carriageway and capable of providing mile a minute speeds outside of urban areas. They are designed to be capable of providing motorway standard journeys that are reliable and resilient to delay. They are also designed to be as safe as motorways, but are generally built where a motorway is not needed, normally because the traffic demand isn't there to fill one.

Expressway is also part of the official name of some roads, for example the Runcorn Expressways, the A38 Devon Expressway, A5300 Knowsley Expressway near Liverpool and A38(M) Aston Expressway in Birmingham.

The A14 is a good example of an expressway

Expressways have been around for many years, although most have not been named as such. The A12 in East Anglia, the A14, the A50 from the M1 to Stoke and the A30 from Honiton to Camborne have, for many years, been dual carriageways for most of their distances and have provided a high standard of performance, breathing life into areas that needed them, and providing relief to those who were plagued by traffic through the years. Some even carry traffic levels higher than some motorways and as a result are now being upgraded to cope.

Although the term only applies in England for Dual Carriageways on the Strategic Road Network, there are several roads that are under the control of a local authority that could be classified as expressways. These include the A380 from the A38 to the East Devon Coast, the A338 Wessex Way and the A130 from Benfleet to Chelmsford. The Heads of the Valleys Road (A465) in Wales and the A720 in Scotland are also good examples of roads that could be Expressways.

Finally, Expressway is also part of the title of Midland Expressway, the owners and operators of M6 Toll, though it is not part of the name of the road itself.

December 2017 proposals

In December 2017, further details were given about expressways as part of a report into the Strategic Road Network. The proposal includes different expressway types (of I - IV) with an aspiration that the highest quality expressways will be given motorway designation and an Ax(M) number. (Source: Highways England Strategic Road Network Initial Report)

Phase 1: a 2-3 lane dual carriageway, with no roundabouts, traffic lights or right turns on the main carriageway, some alternative provision for vulnerable road users, such as cyclists, and slow moving vehicles.

Phase 2: replacing central reservation barriers with safer, rigid concrete barriers for these high flow A-road sections.

Phase 3: introduction of technology and operational changes, including Traffic Officer patrol and emergency areas. A scheme may designate as a motorway and prohibit vulnerable road users and slow-moving vehicles if appropriate alternative provision is available, and there are appropriate terminal points.

Phase 4: motorway designation of the complete corridor.

Current Road From To Current Lanes Junction Types Notes
A1 Chopsticks icon.png A1(M) 10 Chopsticks icon.png A1(M) 14 2 Some GSJ, some Roundabouts, some LILO Requies many junctions to be removed or redesgined to be compliant. Section between J14 and J13 Already Expressway Complaint with 3 lanes with recent A14 Upgrade.
A1 Chopsticks icon.png A1(M) 17 Chopsticks icon.png A1(M) 34 2 Some Roundabouts, many right turns, GSJ at larger roads. Would require many improvemnt to junctions as well as providing an alternative route for forbidden vechicals, animals and cyclists.
A1 Chopsticks icon.png A1(M) 34 Chopsticks icon.png A1(M) 40 2 Mostly LILO, does have a few GSJ. Would require many improvemnt to junctions as well as providing an alternative route for forbidden vechicals, animals and cyclists. Also properties are situated along the A1.
A1 Chopsticks icon.png A1(M) 65 A1 Denwick Interchange D2/S2 Many at-grade junctions Parts still single carriageway
A2 Chopsticks icon.png M2 1 A2 (2 M25) 4 = HS All GSJ Built to motorway standard
A3 Chopsticks icon.png A3(M) 1 A3 Hook Junction 2 Majority GSJ
A5 Chopsticks icon.png M547 A5 Preston Island 2 No junctions or access No changes required.
A6 / A5111 A50 (Exwy) 2 A52 (Exwy) Spondon Roundabout 2 1 Roundabout, rest GSJ
A11 Chopsticks icon.png M11 9A A14 (Exwy) 36 2 All GSJ
A11 A14 (Exwy) 38 A11 Thickthorn Interchange 2 Most GSJ, some LILO
A12 A12 11 A12 33 2 Mostly GSJ
A13 A13 Mar Dyke A13 Baker Street Interchange 3 2 GSJ junctions Only the short section that connects the M25 to Tilbury (via A1089).
A14 Chopsticks icon.png M6 1 A14 (exwy) 21 2 / 3 Majority GSJ
A14 A14 (exwy) 21 A14 (exwy) 26 2 All GSJ This section is currently under construction be an expressway after construction has finished.
A14 A14 (exwy) 31 A14 62 2 / 3 Majority GSJ, few roundabouts such as at A14 J60
A19 A168 (exwy) York Road Interchange A1 80 2, some urban parts 3 Majority GSJ, are some LILO and even right turns. South part of route contiunes as the A168
A20 Chopsticks icon.png M20 12 A20 Dover 2 2 GSJ, then roundabouts and junctions within Dover Section of A20 that connects the M20 to Dover
A21 Chopsticks icon.png M25 5 A21 Pembury Interchange 2 All GSJ Unclear where southern end would be, Pembury Interchange would make most sence since it provides access to the A228 and A264, however that would be within the Weald area of outstanding natural beauty, so would be more likely to be at Quarry Hill Interchange or Vauxhall Interchange with the A26.
A23 Chopsticks icon.png M23 11 A23 Patcham Interchange About 60% 3, 40% 2 All GSJ, some properties.
A27 Chopsticks icon.png M27 12 A27 Southerham Roundabout M27 to A3(M) = 4+HS, rest is majority 2 lanes, one section with 3 and S2 through two towns Loads of roundabouts, loads of LILO, few right turns and GSJ at larger roads. An expressway should beable to reach the west side of chuchester due to the road was orginally designed to be a motorway. HE curretly working on dualing through the towns. Chichester has 6 roundabouts and is extreamly conjested.
A30 A303 Chopsticks icon.png M5 29 66% D2, 34% S2 D2 all GSJ, S2 typical of a normal S2 countryside road.
A30 Chopsticks icon.png M5 29 A303 (exwy) Penzance Parts D2, parts S2 GSJ on D2 parts, mostly roundabouts on S2 parts.
A31 Chopsticks icon.png M27 1 A31 Palmersford Roundabout 2 Mostly LILO or GSJ, few roundabouts and no right turns Passes through the New Forest National Park, so it would be difficult to close junctions to put traffic onto a new side road.

A303 M3 8 A30 (exwy) Penzance D2, parts S2 Pretty much all GSJ. Some at-grade junctions when S2.
A358 A303 (exwy) Southfields Roundabout Chopsticks icon.png M5 25 Mostly S2, some D2 All at-grade junctions Mostly single carriageway, however would make up a M3 to M5 expressway with the A303
A404 Chopsticks icon.png M404(M) 9b Chopsticks icon.png M40 4 2 Mostly GSJ, 1 roundabout and a few minor LILO
A449 / A5 Chopsticks icon.png M54 2 Chopsticks icon.png M6 12 2 Mostly at-grade junctions and roundabout Would use the A449 which is D2, and a realigned A5 to provide a shorter journey between the north and the west.
A421 Chopsticks icon.png M1 13 A1 Black Cat Roundabout 2 All GSJ Recently upgraded to dual carriageway.
A428 A1 Wyboston Interchange A14 (exwy) 31 Parts D2 and S2 At-grade for S2 and GSJ for D2
