Annual crab migration shuts down roads on small island

By Around the Web

(UPI) – Highways and roads have been shut down on an Australian island for an annual occurrence: the migration of millions of red crabs.

The red crabs of Christmas Island migrate every autumn from their homes on the island to the ocean, and many highways and roads are shut down to protect the traveling animals from vehicles.

Some roads that remain open have been outfitted with special bridges the crabs use to avoid traffic, and other roads are cleared by workers with rakes before vehicles come through.
