ABSTRACT:
A highway traffic barrier of the New Jersey style is made from semi-rigid plastic material so that it has some elasticity and will act as a shock absorber, while weighing considerably less than the present day New Jersey style barrier made from concrete. The barrier is hollow and contains interior baffles to provide compartments within the barrier. When in use the barrier is filled with a liquid through filling openings at the top of the barrier and has a weight about equal to the present New Jersey style barriers made of concrete. When the barriers are not filled with a liquid, they weigh considerably less than present New Jersey style barriers made of concrete. When not in use, the liquid is discharged through discharge openings near the bottom of the barriers. Each barrier has a groove at each end which is adapted to receive a key so that the barriers may be joined together to form a highway barrier of the required length. Handles are provided along with recesses in the sides of the barrier to facilitate moving of the barriers manually. The handles also act as reflectors when they are placed in recesses in the top of the barriers.
