PORTABLE BARRICADE AND PORTABLE BARRICADE SYSTEM
A portable barricade includes a road plate, first and second support posts extending upward from end portions of the road plate, a barricade arm extending between the first and second support posts, and a lift coupled one of the end portions of the barricade arm and a corresponding one of the first and second support posts. Actuation of the lift is configured to slide the barricade arm relative to the first and second support members between a retracted position proximate to the road plate and a deployed position distal from the road plate.
