The portable highway barrier of the present invention comprises an elongated barrier body made of lightweight material and having an open cavity therein. The barrier includes an elongated vertical channel at one end and an elongated vertical rib at the opposite end so that a plurality of barrier bodies can be placed in end to end relationship with the rib of one body inserted into the channel of the adjacent body. The barrier can be filled with water or other fluid material once it has been transported to the construction site.
