A water-ballasted protection barrier array and fencing and gate assemblies are disclosed. In one embodiment of the water-ballasted protection barrier array, first fence assemblies are placed in a superjacent relationship with barrier segments to form stacked first fence assembly-barrier segment combinations. The water-ballasted protection barrier array may be constructed by placing second fence assemblies in lateral interposed relationships with two stacked first fence assembly-barrier segment combinations. Alternatively, gate assemblies may be placed in lateral interposed relationships with two stacked first fence assembly-barrier segment combinations to buildout the water-ballasted protection barrier array. A system of connecting lugs and connectors having a common vertical axial alignment such that a connecting rod is inserted therethrough to securably join the components of the water-ballasted protection barrier array.
