There must be a million examples of crazy road signs but I think the following is completely bonkers.
There are several around but in particular Inglewood Road exiting into Mayplace Road (by Phoenix Football ground)
Big sign in tree-lined, grass verged Inglewood Road: Caution New Road layout (or something along those lines).
Apart from the fact that everyone using Inglewood Road have got the idea of a minor road joining a Main Road at a T-junction and the fact that the middle section of the junction has been raised by the use of sleeping policeman what use is the warning.
Believe it or not it is a relatively dangerous junction with vehicles coming from Barnehurst appearing at a relatively high speed around a blind bend but I fail to see the point of this sign.
