M8 motorway (Scotland) M80 motorway; A823(M) motorway; M876 motorway; M898 motorway; M9 motorway (Scotland) M90 motorway; A. A8(M) motorway This page was last edited on 9 August 2015, at 23:34 (UTC). SABRE - The Society for All British and Irish Road EnthusiastsGeographical extremities: north, south, east and westGeographical extremities: north, south, east and west If the two routes multiplex with each other, both junctions are counted. The first is the consideration that any motorway that replaces a short A-road gets a ridiculous number: M876 is a vital link in Scotland's motorway network, but it parallels the A876 and therefore it gets an outrageous number even though all the numbers M81 to M89 are unassigned. That looks highly unlikely now.

References to 'Great Britain' below exclude Northern Ireland, which is treated separately. It is very unlikely … The majority of road lengths in Great Britain is made up of minor roads, with these roads accounting for 215,200 miles in 2019, consisting of 18,800 miles of ‘B’ roads and 196,400 miles of ‘C’ and ‘U’ roads.

The longest motorway in Northern Ireland is the M1 at 38 miles. The longest motorway in Ireland is, for now, the M7 at a distance of 187 km (116 miles).

In 2016 there were: •2,300 miles of motorway • 5,300 miles of trunk ‘A’ road • 23,800 miles of principal ‘A’ road • 18,800 miles of ‘B’ road • 196,300 miles of ‘C’ and ‘U’ road Many cities had urban motorway plans, most of which were not built. The longest, and only, Motorway wholly in Wales is the A48 (M) at 2 miles. The following motorways were planned, but never built. Scotland…

The longest Motorway wholly in Scotland is the M8 at 61 miles, with the M74 coming second at 32.5 miles. Taken together with the A74 (M) and M74 (which is itself being extended by 5 miles) the total continuous length of motorway will be about 370 miles. It also passes through the Manchester Metropolitan University, just South of the John Dalton building, and north of the Union building. This page is still a 'work in progress' and updates / corrections are more than welcome. In addition, the proposal to put a tunnel under the River Thames to the east of Dartford Crossing and the revived Birmingham Western Orbital plans are both described as motorways.There have been many plans for motorways in the UK that have not been built. This page is an attempt to provide details of the longest, highest, etc. classified roads in the British Isles. Roads which used to be motorways but have been downgraded: Generally they result from a main route being realigned, and the old road being downgraded to a lesser status. Text is available under the Creative Commons … The A635(M) is the UK smallest motorway and forms a small part of the Mancunian Way for 0.3 miles before becoming the A57(M). It isn't even signposted. Most are urban link roads, which were allocated separate numbers many years ago, whereas these days they would simply be a spur of the main route. A spur motorway from Baillieston Interchange (meeting the M8 and M73) to Swinton … Scotland (UK) Distance Chart (Distance Table): For your quick reference, below is a Distance Chart or Distance Table of distances between some of the major cities in Scotland (UK). These major roads make up 13 per cent of the total road length. However, none of the A-roads are continuous as they either have a non-dominant multiplex, or motorway (eg There must be many claimants for the title of shortest classified road in GB. Under its charter, motorways are excluded from the remit of Some examples are: Below is a list of plans that were not built (not exhaustive):

There are many examples of two roads meeting each other again and again. North West England: Greater Manchester: A823(M) The A823(M) is a motorway spur from the M90 near Rosyth to the A823 south of Dunfermline. The A74 (M) and M74 were, when they were built, going to be renumbered as M6, creating a motorway over 350 miles long linking the M1 (and thus London) to Glasgow.
