J-J Hooks Barrier Applications

Concrete Traffic Barriers – Safety Applications

Whether temporary or permanent, J-J Hooks traffic barriers reduce the risk of head-on collisions from out-of-control vehicles crossing over the median. The weight of barriers and the interlocking J-J Hooks design provide sufficient inertia to redirect an impacting vehicle without requiring attachment to the highway when a minimum run of 12-foot length barrier is used. Jersey and F-shape barriers reduce the risk of erratic vehicles deflecting back into the traffic stream after barrier collision, avoiding traffic pile ups. Concrete barrier walls also decelerate errant vehicles within tolerable limits.

Concrete construction barriers protect construction workers by creating a high level of containment, by restraining stray vehicles from entering a work zone. Concrete highway barriers allow construction sites to operate safely in close proximity to busy roadways. Precast concrete barriers are useful for redirecting vehicles into new traffic patterns during different phases of construction.

Full-length keyway allows barriers to be placed on bridge decks by use of a U-channel and allows sections to be installed permanently using a mechanical keyway in the roadway with grout as a bonding agent.  Keyway is an optional feature not required in all locations.

Transition Sections, Bridge Barriers, and other special designs available in some locations.
