How about the local council in Cornwall who waited years to put a by-pass around the bottleneck at Double-Bois and then built it - complete with two 'Bat' bridges that cost £300,000.
Yes, that's right - two bridges to assist BATS to fly over the new bypass.
The local council defended building the bridges by way of saying that BATS are protected species and therefore they were entitled to assistance to cross over the road. However the Council were a bit upset by the fact that after considerable research - only about a dozen bats have been seen in the vicinity of the Bridges.
Perhaps the bats need the sign writers of Bolton to show them where the bridges are.
