T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the New Jersey Department of Transportation (NJDOT) Snow Plowing Guide, which establishes operational standards for snow and ice removal services on state highways. The guide provides technical specifications and procedural requirements for contractors performing winter maintenance operations across New Jersey's road network, including two-lane, three-lane, four-lane, and multi-lane divided highways.

The guide defines specific plowing standards for different highway configurations, detailing truck placement, spacing intervals, overlap requirements, and directional protocols. For two-lane highways, three trucks operate with 100-500 foot spacing and 2-foot overlaps to ensure complete snow clearance from centerline to shoulder. For three-lane and four-lane undivided highways, four trucks maintain similar spacing patterns with progressive coverage. Multi-lane divided highways with raised or depressed medians employ four or more trucks with 100-foot intervals between vehicles and consistent 2-foot overlaps. Additional standards address specialized areas including jughandles and switch-back curve ramps, which require specific truck positioning and directional plowing techniques to maximize clear path safety and efficient cleanup. The document emphasizes progressive widening of cleared areas and provisions for equipment alternatives, such as power-reversible plows or graders, when standard truck configurations are unavailable.
