NJDOT Snow Plowing and Spreading Services Guide

This document is a comprehensive operational guide published by the New Jersey Department of Transportation (NJDOT) that establishes standardized procedures for snow plowing and spreading services on state roadways. The guide is designed to ensure consistent, efficient snow removal operations across varying highway configurations and is available to NJDOT personnel and contracted service providers through the department's internal Intranet under the Winter Operations section.

The guide provides detailed technical specifications and truck positioning standards for six distinct highway configurations: two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, multi-lane divided highways with raised medians and no drainage, multi-lane divided highways with depressed medians and drainage, and jughandle intersections. Each configuration specifies precise truck spacing intervals (ranging from 100 to 500 feet between vehicles), overlap requirements (approximately 2 feet), snow placement directions, and equipment recommendations. Additionally, the guide includes specifications for switch-back curve ramps, recommending the use of power-reversible plows or graders to minimize thawing and refreezing cycles. The document emphasizes operational efficiency and traffic safety through progressive widening techniques and coordinated multi-truck formations designed to maximize clear path width while minimizing service duration and disruption to traffic flow.
