Motorway cantilever sign
A blue overhead sign suspended over the motorway from a post on the left, showing an upcoming exit and the following text.
Exit destinations: A580; [Hollow triangle diversion symbol] Liverpool; Manchester; Newton .
Forward destinations: Birmingham, Manchester (S) M6.
Junction number: 23.
The A580 is the East Lancashire Road, one of the UK's first purpose built inter-urban highways, opened in 1934. But today it's not the fastest way to either Liverpool or Manchester from here - you can use the M62 for that - and you have to wonder why they still appear on the signs.
