– Protection for lighting columns
– Adjacent to structures
– Level difference between carriageways
Where space permits, dual CB will accommodate level differences between carriageways, lighting columns and cables between the barriers and protect maintenance workers.
Bifurcation and Change of Alignment
– Transition to dual barrier
– Central reserve crossover
– Change of set-back
Bifurcation and change of set-back are most commonly used to accommodate bridge piers and other localised hazards. This is required when the pier or gantry leg has insufficient resistance to withstand impact thus requiring a secondary structure as protection.
Barrier alignment can be changed to allow CB to cross the central reserve when set-back changes from one carriageway to the other.
CB can also be locally widened, to accommodate signs or gantries mounted on CB, and to interface with bridge piers or gantry bases that are capable of withstanding full impact loads.
