Wide Angle Wednesday: Signs & Symbols

Words, numbers, colours, shapes - we're bombarded with them on the roads these days - but I guess the most important sign here is the solar powered one warning of the height of the bridge... It has only appeared recently, near the studio where I do Pilates, so I'm assuming something has tried to get under said bridge and failed - some signs of minor damage on the underside! 

Oooh forgot ( a sign of old age? ) - this is number 500 ( a sign of stickability? )!
