The M56 Bowdon View Bridge is a two lane single direction bridge over the M56 Motorway. Bowdon View Bridge carries westbound traffic from Manchester off the M56 at Junction 7 and over the M56 to Bowdon Roundabout, where it links to the A556.
The bridge will be demolished on the weekend commencing Friday 15th October to Monday 18th October. The new bridge will be installed the following weekend, commencing on Friday 22nd October to Monday 25th October.

What this means is that if you’re heading towards Wales (maybe to to visit Llandegla / CYB / Marin trail etc, for instance) from the Manchester area over either of these weekends, your journey will be screwed as the M56 will be closed: you’ll have to go all the way round past the Trafford Centre, so you’ll need to add on at least 90 minutes I’d reckon. Avoid it if you can.
