Out and about – the A601(M)

Today I went for a little drive around Lancashire and collected some images of old and new signs, and several of them have caused me to get a bit grumpy due to elementary mistakes that either make a sign cluttered, or suffering from design errors. Instead of just griping, though, I intend to demonstrate how the same sign could have been designed as a constructive critique and a sort of workshop for sign designers who need a bit of inspiration.

The simple fact is that whilst Chapter 7 is great for telling you where to put blocks, etc, there is virtually nothing on how to assemble a sign in the first place. The best information available (and we presume will become part of Chapter 2 when it is eventually published) is currently two Interim Advice Notes that were helpfully drafted by Matthew Youell of Highways England. These two documents are great, and represent the first real leap forward in advance direction sign guidance since 1964.

So, here’s my ‘rogues’ gallery, and my own interpretation of it.

A601(M), Carnforth Spur

The A601(M) is a weird little road. It originally was the end of the Lancaster Bypass section of the M6 until it was extended north in 1970. It then gained a single carriageway extension to the south in 1987 or so, to connect to the nearby quarries. It isn’t a trunk road, so the signs are all maintained Lancashire County Council.

Note: the future of this motorway is in doubt, as there are development proposals that will see special road status removed from the entire route. That probably explains why the old signs have survived for so long.

Junction 35A

The worst offender at junction 35A in terms of adherence to design rules has to be this assembly.

  • The new A6 sign on the left is at least on a passively safe post, but the problem is this sign should really be a chevron type (flag) sign, however the geometry of the roundabout is from 1960, before ‘modern’ roundabouts were thought of, so there is no exit deflection. In this instance I’d be inclined to say it’s fine as it is.
  • The signs pointing towards the motorway lack the motorway symbol, and feature an erroneous use of a motorway panel inside a blue local bordered sign. Notwithstanding the fact blue bordered signs should have been removed by 31 December 2014, this combination was never really intended and against good practice.

Due to the amount of sign clutter and risk of confusion that multiple signs on a roundabout’s circulatory carriageway can cause, it is not now considered best practice to provide multiple signs at a roundabout in this style. However, if it is deemed desirable I would suggest the following replacement sign.

At this point the destinations reached via the M6 are irrelevant, as the M6 itself is the destination. Hence a cluttered assembly can be reduced to provide just two relevant destinations to traffic entering the motorway. You will notice this sign is NOT blue. Traffic does not directly enter the motorway at this point so the use of the motorway symbol and a blue background sign is actually incorrect and misleading.

Despite the presence of the non-passively safe lighting column, it is good practice to consider having crash friendly sign posts on the assumption that the column will eventually be replaced.

  • The assembly is separated to the point of being useless; the second sign is too far away from the decision point; traffic is already committed to the motorway.
  • The signs are old, but not told enough to be exempt from the design requirement to have a motorway symbol on them.
  • The motorway is A601(M), not M6.

A601M-35A-2

The same de-cluttering principles as the above sign have been applied. The sign gives only the relevant information at this point. The next junction is the decision point for M6 north or south. We have an unfortunate tendency to overload drivers with information before they need it and this causes more problems than it solves.

The motorway itself

The advance direction sign for the A601(M)’s junction with the M6 is hidden by foliage, and is thus extremely hard to photograph. Throw in the March sun and all I have is a terrible quality photo.

  • The sign is hidden by foliage and can’t be seen until the last minute.
  • The roundabout symbol is missing the ‘cut out’ to denote the correct circulation.
  • A stub arm is missing.
  • The sign is outdated and needs updating to reflect LTN 1/94 design principles.

A601M-35-1

  • The regional destination of “The North” is replaced with the correct “The LAKES”.
  • North and South have been shown with the M6 number, but this could easily be omitted with no detrimental effect. Likewise for “Blackpool (M55)”
  • The ahead destination confirms that there is still a route subject to motorway regulations.

This entire assembly makes me grind my teeth together; the wrong lengths of Lattix post, the re-use of an old sign on a new passively safe structure, and the wrong use of block spacing on the left hand, newer, sign. I’d question the necessity of the right hand signs entirely, and the left hand one should look something like this:

A601M-35-3

Going around the roundabout we can see that this assembly is also in need of some serious improvement:

  • Some road numbers would be beneficial; the coverplate says “(A6)”.
  • The tourist sign is not needed; these destinations should have correct publicity to tell people to follow the relevant ‘main’ destination until a closer decision point. The brown sign replaced a much older installation referring to Frontierland, a long since demolished theme park in Morecambe.
  • The signs should have been moved up to avoid the over sized space between them.
  • The Services flag sign has two side extensions that are way beyond what is needed.
  • The right hand assembly is not needed.

By bringing everything onto a single assembly, it reduces the overall space taken, and provides the same information on fewer signs:

A601M-35-4

Note; the services referred to are officially a truckstop, so the use of the lorry symbol, whilst strictly non-conventional, is at least of use to HGV drivers.

The only problem with this sign is it is old and has a badly aligned “Truckhaven” coverplate on it.

Nearby signs

There are a few other bothersome signs in the near vicinity. These all have similar issues to those raised above such as missing route numbers, missing symbol cut outs, and poorly applied coverplates.

It does bother me slightly that on a motorway that is barely 1.5 miles long, that virtually every major sign assembly (that’s 13 of them) needs improvement in one way or another. Not a great example to follow.

  1. Ouch. Taken all in all, the A601(M) might be the wrongest motorway in the UK. It has the wrong number, its eastern half is built to the wrong standards and it has signs that are all wrong. Remind me, does traffic drive on the left or the right?

    (Incidentally I think you’d invite more comments if the “add a comment” button was at the bottom of the post and not the top – I didn’t see it when I first started visiting. Feel free to remove this site feedback comment before publishing!)

  2. Looks like the County Council needs your demo designs sent over!

    Pah! Come down to Oxfordshire, Where Blue-bordered signs frolock alongside fields!
