pathetic motorways and the walton summit motorway i resent the implication being the webmaster of the aforementioned site the site is not a wacky website but a factually accurate record with comments tossed in you are allowed to educate without boring people you know uncleg is proceeding from a false assumption that the classification of all motorways is listed on signposts there are many other examples of unsigned motorways where official dft documentation exists such as the tiny a m in manchester or the a m in cambridgeshire the walton summit motorway is an extremely unusual case whilst it is quite true that there are many short motorway spurs that are simply a part of the parent motorway such as the m spur at luton the walton summit motorway does not fall into this category as is clearly pointed out the walton summit motorway is neither part of the m nor part of the m but does have motorway classification because it inescapably leads to the roundabout that links the two there is no other stretch of motorway in the uk where a short spur motorway actually links two different motorways if it is part of the m as the start of restrictions sign at the bottom of the hill implies then why does the directional flag sign state m m meaning a part of the m this is a common form of signage throughout the uk system but is unusual to be found upon a motorway a similar item can be seen with reference to the example of the a m above the start of restrictions sign when heading westbound on the a m clearly states a m but the dft documentation states otherwise it's the statutory instrument no the city of manchester mancunian way a m and a m mancunian way slip roads special road scheme confirmation instrument that you're looking for if you're really concerned about its accuracy a pdf copy is available on pathetic motorways but a simple google search will turn up the relevant central government pages if you doubt the source material the walton summit motorway is a motorway without a number hardly an unusual concept in road terms where most roads either do not possess a classification number or is of a c d or u classification which do not appear on road signs it is bowever an unusual concept in motorway terms
