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.
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.
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.

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.

Where a route uses two diffrent roads but up to 1 junction of one of the roads they are grouped togeather.
|Current Road||From||To||Current Lanes||Junction Types||Notes|
|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.|
|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.|
|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.|
|Denwick Interchange||D2/S2||Many at-grade junctions||Parts still single carriageway|
|M25)(||4 = HS||All GSJ||Built to motorway standard|
|Hook Junction||2||Majority GSJ|
|Preston Island||2||No junctions or access||No changes required.|
|/||(Exwy)||Spondon Roundabout(Exwy)||2||1 Roundabout, rest GSJ|
|(Exwy)||Thickthorn Interchange||2||Most GSJ, some LILO|
|Mar Dyke||Baker Street Interchange||3||2 GSJ junctions||Only the short section that connects the M25 to Tilbury (via A1089).|

|(exwy)||(exwy)||2||All GSJ||This section is currently under construction be an expressway after construction has finished.|
|(exwy)||2 / 3||Majority GSJ, few roundabouts such as at A14 J60|
|York Road Interchange(exwy)||2, some urban parts 3||Majority GSJ, are some LILO and even right turns.||South part of route contiunes as the A168|
|Dover||2||2 GSJ, then roundabouts and junctions within Dover||Section of A20 that connects the M20 to Dover|
|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.|
|Patcham Interchange||About 60% 3, 40% 2||All GSJ, some properties.|
|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.|
|66% D2, 34% S2||D2 all GSJ, S2 typical of a normal S2 countryside road.|
|Penzance(exwy)||Parts D2, parts S2||GSJ on D2 parts, mostly roundabouts on S2 parts.|
|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.|

|Penzance(exwy)||D2, parts S2||Pretty much all GSJ. Some at-grade junctions when S2.|
|Southfields Roundabout(exwy)||Mostly S2, some D2||All at-grade junctions||Mostly single carriageway, however would make up a M3 to M5 expressway with the A303|
|2||Mostly GSJ, 1 roundabout and a few minor LILO|

|Wyboston Interchange||(exwy)||Parts D2 and S2||At-grade for S2 and GSJ for D2|
