Where is it?
M60 junction 26, where Manchester's ring road motorway interchanges with the parallel A560, allowing westbound to westbound and, er, westbound to westbound movements.
It was spotted by Peter Edwardson.
What's wrong with it?
It's half a junction, filling in bits of movements that the junctions either side either don't have or, in some cases, already do have. There's no access for traffic heading eastbound on the A560 — but it's still forced to stop at a set of traffic lights where the sliproads take it in turns to cross each other over. The layout of this means that heading eastbound on the A560, and waiting at the traffic lights, there appears to be a sliproad leading up to the left onto the motorway. The danger of this isn't just potential — numerous confused drivers have ended up facing the wrong way round on the M60 here. In addition, the A560 is dualled to the east but single to the west — and of course the west is the busier part.
Why is it wrong?
It shouldn't really exist at all — the reason it's wrong is that it's forced into existence by silly junctions at each side that leave out certain movements (there's no access to the westbound M60 from the junction further east, for example). If a couple of sliproads had been built there, it may have cost more, but would have avoided this.
What would be better?
Either add in the missing movements at the other junctions, or grade-separate this junction, so there's no traffic lights and no opportunity for confused pensioners to end up facing the wrong way on a busy motorway. There's no shortage of space for two levels of flyovers and room for them to merge in properly with the A560.
Right to reply
I'm with Iain Benson. That merger from the A560 onto the M60 going north is horrible. I hate doing it, but unfortunately it's my local junction to the M60. Going north is quite maddening. You get forced onto the fast lane and can easily get stuck there as all the M60 traffic comes rushing in from the other lanes meaning it's very difficult to get yourself out. Thankfully I don't use it during rush hour as I can imagine it would be horrendous.
To be honest, much of the M60 through Stockport is a mess, partly caused by the botching together of two motorways into one, and partly due to sheer lack of space to do anything proper.
Not an ideal junction, agreed, but there are no need for any problems here. There are 'No Entry' signs in the correct places, so no one should be going the wrong way up slip-roads. And traffic lights at the end of slip-roads are a common occurrence in England so that shouldn't be causing any problems either, (especially as advanced warning is given on the overhead gantry as you leave the M60 that there are traffic lights ahead).
