A route used by toads trying to reach their breeding grounds is to be closed for the mating season.
Hundreds of amorous amphibians crossing Charlcombe Lane in Bath have been squashed by passing cars in previous years.
To protect them, the council will block the road to through traffic from the end of January until the end of March.
Similar closures - and a helping hand from local residents - in 2003 and 2004 saved over 1000 toads, frogs and newts.
Bath and North East Somerset councillor Rosemary Todd said: "The last two years have saved the lives of hundreds of amphibians
"I hope users of Charlcombe Lane will understand why it is important for us to close the road - we apologise for any inconvenience this will cause."
People living in Charlcombe Lane will still be able to get to their homes, but signs will be put up to encourage others to follow diversions.
