Congestion Mitigation:

As the daily traffic on a bridge increases over time, bridge authorities must find a way to increase the capacity of the bridge to match the traffic flow.  New construction is extremely expensive, and often times it is not even an option.  The cost-effective and expedited method of increasing bridge capacity is to create a managed lanes facility where the lane configuration of the bridge is flexible and additional lanes are made available to the peak traffic direction.  This can be done with cones and overhead lights, but crossover accidents will occur, causing serious injuries and fatalities.

Moveable barrier creates managed lanes for bridges while providing positive barrier protection.  The barrier wall is lifted from the road surface and moved laterally one or more lanes at speeds up to 16 km/h to meet peak traffic demand, while eliminating crossover accidents.

Speeding Construction and Increasing Safety:

Bridge work projects face multiple challenges.  Limited space for vehicles, equipment, and workers results in an increase in the number of construction stages, prolonging the job and raising the cost of construction.  Safety is also compromised if all work must be performed in a cramped and inefficient work zone, and bridge work zones that create a flexible work space by utilizing cones and barrels are inherently dangerous to workers and motorists.

Moveable barrier creates a safe, flexible work zone for bridges that allows contractors to expand the work zone during off peak traffic hours, and reduce or even close the work zone during peak traffic hours to maximize traffic flow.  Larger, more efficient construction equipment can be used in the expanded work zone, combining or eliminating stages and allowing many re-decking projects to be completed in one construction season rather than two.
