NJDOT Snow Plowing Guide

This document is the New Jersey Department of Transportation (NJDOT) Snow Plowing Guide, a technical and operational document that establishes standards and procedures for snow removal services on state highways. The guide provides detailed specifications for contractor operations across various highway configurations and road types throughout New Jersey.

The guide establishes plowing standards for multiple 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 each configuration, the document specifies truck positioning, spacing requirements (typically 100 to 500 feet between trucks), and overlap specifications (approximately 2 feet) to ensure complete snow removal coverage. The guide also addresses specialized areas including jughandles and switch-back curve ramps, with specific directional plowing techniques for each condition. Equipment requirements recommend power-reversible plows or graders for optimal efficiency, particularly on switch-back ramps. The standards emphasize progressive widening on low sides and maximum clear path maintenance for cross traffic. These operational guidelines ensure consistent, efficient snow removal across all state-maintained roadways and serve as the basis for contractor performance requirements and service-level agreements.
