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.
