A vehicle barricade has two concrete walls contiguously disposed along either side of a roadway for defining a checkpoint. A shaft is pivotally secured to the roadway and extends transversely between the concrete walls. A barrier plate is pivotal with the shaft between a first horizontal position and a second angularly disposed position adapted for preventing vehicle passage through the checkpoint by engagement of the barrier plate with the vehicle. A shaft retaining system is provided for preventing removal of the shaft and the barrier plate therewith from the roadway surface.
