Motorway cantilever sign
A blue overhead sign suspended over the motorway from a post on the left, with a downward-pointing arrow indicating the left-hand lane, and the following text.
M58 [Hollow triangle diversion symbol] ; Southport; Liverpool; Skelmersdale.
Junction number: 26.
The M58 must be one of England's oddest motorways - unfinished at both ends, and full of strange junction layouts. It's yours to enjoy with a left turn here, or a right will take you in to Wigan.
