T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the New Jersey Department of Transportation (NJDOT) Snow Plowing Guide, which establishes operational standards and procedures for winter snow removal services on state highways. The guide provides technical specifications and truck positioning protocols for contractors and NJDOT personnel responsible for snow plowing operations across various highway configurations throughout New Jersey.

The document outlines detailed plowing standards for different 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 medians and depressed medians with drainage. For each configuration, the guide specifies truck sequencing, spacing requirements (typically 100 to 500 feet between vehicles), overlap patterns (generally 2 feet), and positioning protocols to ensure complete snow removal from shoulders to gutters. Specialized procedures are provided for jughandles and switch-back curve ramps, with recommendations for equipment types such as power-reversible plows or graders. The guide emphasizes progressive widening of cleared areas and efficient cleanup methods to minimize traffic disruption and maximize public safety during winter storm events.
