Wigan
Smart Motorway gantry sign
A gantry structure spanning the motorway with electronic signals, blue signs showing an exit and the following text.
Exit destinations: A49 [Solid triangle diversion symbol] Wigan.
Forward destinations: Preston M6.
Junction number: 25.
In this part of Lancashire the M6 gets a bit single-minded about going to Preston, and until we reach it there will be little indication that anything exists north of there.
