New Jersey Barrier Design

Originally developed in the 1950s, the modular design of NJ barriers adds versatility for minimizing vehicle damage and preventing vehicle crossovers resulting in a likely head-on collision. Taller NJ barriers deliver the added advantage of blocking most oncoming headlights.

Our precast concrete barrier systems have many benefits over plastic barriers:

  • Stronger and heavier: reduce the risk of fatal and severe injury crashes
  • Reduced costs: substantial cost savings and less maintenance
  • Specifications: connect to F-style barriers and constant slope barriers
  • Versatility: available in several lengths and manufactured to specifications

Depending on the type of barrier that your project requires, the experienced team at Westcon Precast provides a range of models at differing dimensions to accommodate a wide range of projects. Look below for the engineering specifications and see if the New Jersey barrier is the right barrier choice you need to best suit your project.
