Bridges help bats get home safely

One of the two bat bridges

Two special bridges to help bats find their way home have been built as part of a £42m road scheme in Cornwall.

The bridges cost a total of £250,000 and are made out of steel wire and netting stretched in a V-shape.

They replace some hedges that the protected creatures used to find their way to their roosts near Dobwalls, using sound reflection.

Other wildlife protection measures on the bypass include tunnels for badgers and otters, and a water run for fish.

The Highways Agency will monitor the bridges for five years to monitor their success.
