Divided highway systems utilize various methods to separate oncoming traffic lanes. The main method used is the placement of concrete barrier between opposing lanes. The individual Departments of Transportation in each state have specific standards for the size of highway barrier wall to be utilized in road construction projects. These protective concrete barrier wall systems are also widely known as jersey wall, jersey barrier, median barrier, medial barrier, or highway dividers. Below is a list of the wall sizes or concrete barrier dimensions normally being used in each state. Wall styles also vary by state.
