Site work for a road / highway in Sparta, New Jersey. Conceptual plans call for site work for a road / highway.

The purpose of the Route 15 Corridor, Rockfall Mitigation, Contract B project is to improve the overall safety for the traveling public along the Route 15 corridor in Rockaway & Jefferson Townships in Morris County and Sparta & Lafayette Townships in Sussex County. The NJDOT Rockfall Hazard Management System (RHMS), has identified twenty (20) rock slopes that pose a high risk for falling rock events within the project limits. Seven (7) of these slopes have been classified as High Hazard Slopes, under the Federal Highway Administration (FHWA) Rockfall Hazard Rating System, due to the occurrence of past rockfall events and the potential for rockfall to impact the roadway. The mitigation measures proposed will improve safety by reducing the number of falling rock events along Route 15 utilizing rockfall protection, removal, and stabilization measures. Additionally, substandard existing guide rail at the rockfall sites will be upgraded to meet current MASH standards, as needed.
