What a complete waste of money these signs are!!! In all the many years they have been installed, I can honestly say they have been of use just ONCE (advised of the A338 into Bournmeouth being closed)
They are quick to tell us that there is queue on the M25 etc yet fail to tell us of the impending traffic 2 miles up the road !!
Save millions & stick a sign up next to the road saying 'tune in to Radio Solent for the latest traffic reports'
