The 460-CTB-1E precast concrete barrier is an excellent choice when you need an added layer of safety to transition the height of 690 precast barriers from high to low during highway construction.

The low profile transition of a 460-CTB-1E precast concrete barrier is ideal for minimal visual impact for most roadside or shoulder applications during highway construction. It has the added advantage of establishing defined workspaces and shielding drivers from driving off the side of the roadway into natural or manmade hazards, such as rivers, ditches, or rock bluffs.

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

  • Safety: sloped profile design offers a smooth transition for the existing roadway
  • Specifications: connect to the standard 690 precast concrete barrier height
  • Reduced costs: reinforced concrete that is easily repaired and reused
  • Visibility: improves visibility and protection for roadside and shoulder work zones

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 460-CTB-1E transition barrier is the right barrier choice you need to best suit your project.
