Lollipop man - for otters?

We've all seen lollipop men and women help us across the road - but now there's one for otters.
And a special tunnel has been made so otters can cross the road without being hit by cars.
A tunnel under a busy road in Herefordshire is helping the local otters cross safely.
Signs have also been put on the road which warn motorists of the presence of otters.
When roadworks were needed to help with floodwater, workers also dug the special tunnel.
Each year more than 400 otters are killed on roads in the UK.
