Low profile concrete barrier is used in construction areas where speed limits are 45 mph or lower and are available in 20″ lengths. The minimal visual impact of low-profile barriers can be used to establish defined workspaces that provide increased safety for workers, and shield drivers from trees, light poles, and other fixed roadway features.
Pedestrians, workers, and drivers all benefit from LPB protection since it improves visibility and offers positive protection.
LPB can provide protection for a variety of road users, as well as workers who are in close proximity to traffic, whereas the typical F-shape barrier with end treatment might hinder line of sight.
