NJDOT Snow Plowing Guide

This is an operational guide published by the New Jersey Department of Transportation (NJDOT) that establishes standardized procedures for snow plowing services on state highways. The document provides technical specifications and best practices for winter operations management across different highway configurations and conditions.

The guide details plowing standards for multiple highway types, including two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, and multi-lane divided highways with both raised and depressed medians. For each configuration, the document specifies truck positioning, spacing intervals (typically 100 to 500 feet between vehicles), overlap requirements (approximately 2 feet), and operational sequences. Additional standards cover specialized areas such as jughandles and switch-back curve ramps. The guide emphasizes equipment coordination, requiring power-reversible plows or graders for optimal efficiency on ramps and curves, and mandates that contractors maintain progressive widening of cleared areas and proper snow placement to gutters and shoulders to maximize traffic safety and operational effectiveness.
