NJDOT Snow Plowing Guide

This document is an operational guide published by the New Jersey Department of Transportation (NJDOT) providing standardized procedures for snow plowing services on state highways. The guide establishes best practices and performance standards for contractors and NJDOT personnel responsible for winter road maintenance operations across New Jersey's highway system.

The guide specifies truck positioning, spacing, and operational standards for snow plowing across various highway configurations, 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 two-lane highways, Truck #1 guides on the centerline with the plow extending into the adjacent lane, Truck #2 follows approximately 500 feet behind with a 2-foot overlap, and Truck #3 follows 100 feet behind Truck #2 to clean remaining areas to the gutter line. For more complex configurations, additional trucks maintain 100-foot spacing intervals with 2-foot overlaps of previously plowed areas. The guide also addresses specialized applications including jughandles and switch-back curve ramps, with recommendations for equipment types and operational techniques to minimize thawing and refreezing cycles and ensure efficient snow removal and cleanup.
