Christmas Island rangers have taken road safety to a whole new level with the construction of a “crab bridge” more than the island’s busiest road.

In preparation for the annual spawning season, rangers have been setting up barriers along the roadside to stop the crabs from being crushed under the wheels of cars.

A five-metre-high bridge has also been constructed at one point along the road to aid the crabs move across the island and continue their migration.

Christmas Island Tourism Association marketing manager Linda Cash stated aside from the practical use, the bridge had also become a tourist attraction.

“Sydney can have its Harbour Bridge, and San Francisco its Golden Gate bridge, but it is our crab bridge which is currently wooing vacationers from all more than the globe,” Ms Cash said.

“The ubiquitous crabs take the most direct route possible from their burrows in the rainforest terraces down to the coast, turning the roads, golf course and beaches into a crimson carpet.”

Rangers on Christmas Island have also constructed 31 underpasses across the island to assist the migrating crab masses en route to spawn.

Far more than 50 million crabs are expected to be involved in the annual migration, predicted by the Tourism Association to take spot on January six.
