CyclopsShield™ Safe Culvert End

Cyclops-Shield™ provides protection against the blunt ends of roadside culverts by deforming upon vehicle impact creating a traversable surface. Culverts located under crossroads and driveways present a vehicle snagging hazard when installed parallel to the roadway.

Cyclops-Shield™ is a MASH compliant alternative to expensive traversable gratings and does not affect the hydrology of the culvert.
