Long, steep slopes along I-87 through the Adirondack corridor, the Palisades Interstate Parkway, Route 97 along the Delaware River, and the Niagara Gorge 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. Precambrian Adirondack anorthosite, Palisades diabase sill, and Devonian shale exposures 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 York 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's Niagara Gorge and historic bridge projects demonstrate proven New York rockfall capability.
Purpose-Built Equipment — Spider Excavators install attenuator cable anchors on the steep mid-slope positions that define system performance — accessing the critical anchor points that determine whether the system reduces energy as designed.
Rockfall Specialists, Not Generalists — Every Access Limited crew is trained specifically for steep slope and rockfall work. This is not a side service — it is the entire company.
Engineered Solutions — Every rockfall attenuation systems installation in New York is designed by engineers for the site-specific conditions — not selected from a generic product catalog.
24/7 Emergency Response — When a rockfall emergency demands immediate rockfall attenuation systems deployment on a New York corridor, Access Limited mobilizes with the specialty equipment and trained crews to respond.
