T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the NJDOT Snow Plowing Guide, prepared by the New Jersey Department of Transportation. It serves as an operational guide for snow plowing services on state roadways, establishing standardized procedures for contractors and agency personnel engaged in winter maintenance operations.

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 either raised medians without drainage or depressed medians with drainage. For each configuration, the document specifies truck positioning, spacing intervals (typically 100 to 500 feet between trucks), and overlap requirements (generally 2 feet) to ensure comprehensive snow removal from roadways to shoulder and gutter lines. Additional guidance addresses specialized areas including jughandles and switch-back curve ramps, with specific instructions for truck sequencing and snow placement to maximize traffic safety and operational efficiency. The guide emphasizes that switch-back curve ramps should preferably be plowed using power-reversible plows or graders, with progressive widening to the low side during storm conditions and snow relocation to the low side upon storm completion.
