Long, steep slopes along I-80 through the Delaware Water Gap, I-78 through the Watchung Mountains, Route 23 along the Palisades, and Route 15 through the Highlands allow rockfall to build energy over hundreds of feet of vertical fall — reaching velocities and impact forces that exceed the capacity of any single containment barrier. Palisades diabase sill, New Jersey Highlands gneiss, and Delaware Water Gap quartzite on these slopes require a system that reduces energy incrementally rather than absorbing the full impact at one point.
Access Limited designs and installs rockfall attenuation systems across New Jersey for corridors where fall height and block size combine to produce energy levels that single-barrier solutions cannot handle.
Curtain attenuators consist of mesh panels suspended from horizontal cables across the slope face. Falling rock hits the curtain, transfers energy to the cable system, and drops to the slope surface at reduced velocity — repeating the process through multiple curtain stages.
Hybrid systems combine attenuator curtains on the upper slope with a flexible rockfall barrier at the base — the curtains reduce the energy so the terminal barrier can be sized for practical installation rather than the full unattenuated impact.
Access Limited brings specialty rockfall equipment to New Jersey's constrained, high-traffic corridors.
