T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the NJDOT Snow Plowing Guide, issued by the New Jersey Department of Transportation. It provides operational standards and procedures for winter snow removal services across New Jersey's state highway system.

The guide establishes standardized plowing protocols for different highway configurations, including two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, and multi-lane divided highways with raised or depressed medians. For each highway type, the document specifies truck positioning, spacing requirements, overlap specifications, and directional snow placement procedures. Key specifications include maintaining 100-foot spacing between trucks with approximately 2-foot overlaps on previously plowed areas, and designating lead trucks to guide on centerlines or lane lines depending on highway type. The guide addresses specialized situations including jughandles and switch-back curve ramps, with detailed instructions for snow management at road intersections and medians. For switch-back curve ramps, the document recommends using power-reversible plows or graders for optimal efficiency, with progressive widening toward low sides. These standards ensure consistent, efficient snow removal operations across varying highway configurations and weather conditions throughout New Jersey's transportation network.
