Conservation rules slow Norfolk roadworks to snail's pace

Rare species of snail found near A47 will be monitored in new home until 2023

Snails with legally protected status could delay a road scheme by five years as a project to rehome them is kept under observation.

Ditches alongside a section of the A47 in Norfolk are a habitat for little whirlpool ramshorn snails, whose shells measure just a few millimetres in diameter.
