Thousands of traffic signs are being brought down across the country as part of a Government drive to rid our streets of clutter.
Transport Secretary Patrick McLoughlin has urged local authorities to continue the cull.
Mr McLoughlin has also unveiled a new document called Reducing Sign Clutter that provides guidance to local authorities on how to remove unnecessary traffic signs as cost-effectively as possible.
In London alone 8,000 repeater signs and 4,000 poles installed on the capitals roads in the early 1990s have been ripped out. Laid out side by side these would stretch almost 2.5 miles.
