The Quickchange® Moveable Barrier system is designed to create a positive traffic barrier between opposing lanes of traffic and between motorists and construction work areas.
Quickchange® Moveable Barrier (QMB) is designed to cost effectively increase capacity and reduce congestion by making more efficient use of new or existing roadways. Applications include high volume highways where additional right-of-way may not be available, where environmental concerns may exist, or where the lack of funding may slow or inhibit support for new construction.
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.
