Median Gates
The installation of continuous concrete barrier is often the preferred safety barrier option on urban motorways providing heavy duty impact resistance with minimal maintenance. Median gates are designed to provide vehicle access during emergencies or road maintenance. Median gates should facilitate ease of operation, with manual operation often preferred eliminating the potential for electrical or mechanical failure. When the median gate is closed, it is designed to function as a continuous safety barrier system.
The ArmorGuard Barrier Gate is a highly mobile, steel gate system designed to create safe, controlled access points in temporary or emergency traffic management situations.
Frequently Asked Questions
What is the purpose of a median gate?
A median gate is designed to provide emergency vehicle access or facilitate a contraflow.
What is a contraflow?
A contraflow is a temporary traffic management arrangement where vehicles are directed to travel in the opposite direction to the normal traffic flow, usually on one side of a divided road or motorway, to maintain traffic movement during construction, maintenance, or emergencies.
What are the advantages of using a contraflow?
The use of a contraflow minimises disruption to traffic during road maintenance by providing two-way operation on one carriageway.
What site control measures should be implemented before opening a median gate?
Appropriate traffic control is required to ensure reduced vehicle speeds through the crossover point.
What is the advantage of a gate that is opened manually?
A manual operation eliminates the potential for electrical or mechanical failure.
Can a median gate be installed within a section of median guardrail barrier?
A median gate is regarded as a rigid barrier and typically designed for connection to a concrete barrier. The difference in system stiffness between a median gate and guardrail barrier would require a specially engineered transition.
What are the recommended maintenance requirements for a median gate?
Jockey wheels should be inspected to ensure they correctly operate and the area adjacent to the median gate should be kept free of debris.
