Not every rockfall corridor in Pennsylvania requires a high-energy flexible barrier. Along I-76 along the Pennsylvania Turnpike, Route 22 through the Lehigh Valley, I-80 across the Allegheny Plateau, and I-99 through the Ridge and Valley, many slopes produce moderate rockfall — small to medium blocks that roll, slide, or bounce into highway ditches. Catch fences intercept this material at the ditch line or on benches cut into the slope, preventing it from reaching the roadway.
Access Limited installs catch fence systems across Pennsylvania — engineered for the block sizes, fall trajectories, and containment requirements specific to each PennDOT corridor.
Ditch-line catch fences are installed along the inside edge of the highway ditch — the last line of defense before rockfall enters the travel lanes. These systems are sized to contain the rockfall volume and energy anticipated from the upslope source.
Bench-mounted fences are installed on intermediate benches cut into the slope — intercepting rockfall partway down the face before it can build energy on the lower slope.
Temporary catch fences provide immediate rockfall protection during construction, emergency response, or interim periods while permanent systems are designed and installed.
Access Limited's Cementon Road Bridge project showcased the specialized capability PennDOT corridors demand.
