The M56 from the M60 (Manchester) junction 1 all the way to junction 15 is carpeted in litter in the central reservation. Not surprising as I witnessed a waste transport vehicle with rubbish flying off the top. I came off at the same junction and later I saw it turn off where there was a sign to a waste site. When is the Highways Agency going to tackle this? The HE contractors could spend weeks or months cleaning this only for a single lorry with an unsecured load to obliterate it again in the course of 1 journey of 45 minutes!
