NJDOT Snow Plowing Guide

This document is a guide published by the New Jersey Department of Transportation (NJDOT) detailing standardized procedures for snow plowing operations on state highways. The guide establishes operational protocols for contractors and NJDOT personnel responsible for maintaining roadways during winter weather events. It applies to various highway configurations throughout New Jersey and serves as the technical standard for snow removal services across the state's transportation network.

The guide presents five primary plowing configurations with specific truck deployment and positioning standards: two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, multi-lane divided highways with raised medians, and multi-lane divided highways with depressed medians with drainage. For each configuration, the document specifies truck sequencing, spacing intervals (typically 100 to 500 feet between trucks), overlap requirements (approximately 2 feet), and directional plowing patterns. Additional guidance covers jughantles and switch-back curve ramps, detailing optimal equipment deployment and operational techniques. The standards emphasize maximizing clear path coverage while minimizing thawing and refreezing cycles through progressive widening and efficient truck coordination. These operational standards ensure consistent, effective snow removal across New Jersey's diverse highway infrastructure during winter weather conditions.
