Motorways under construction or planned[edit] The £380m A1(M) Leeming - Barton upgrade[14] commenced construction in Spring 2014 with completion scheduled for Spring 2018. The only other new motorway constructions currently being planned in the UK is a motorway running south of the city of Newport, south Wales. This motorway remains to be properly named, only being described as the M4 relief road. Unbuilt motorways[edit] There have been many plans for motorways in the UK that have not been built. Below is a list of plans that were not built (not exhaustive):

M12 in 3 forms (although a small part was built and is not used - a stub sliproad):[15]

From the London

Hattersley
to Stannington (an outer-suburb of Sheffield) and to link that tunnel to a new underground motorway providing links to the M1.[27]

Many cities had urban motorway plans, most of which were not built. London,[28] Newcastle,[29] Liverpool,[30] Manchester/SELNEC and Glasgow[31] all had extensive plans. Northern Ireland[edit] M-designated motorways[edit]
