T0777 Attachment 4 - Snow Plow Guide.pdf

This is a Snow Plowing Guide document issued by NJDOT (New Jersey Department of Transportation) that establishes operational standards for snow plowing services on various highway configurations. The guide applies to state-maintained roadways in New Jersey and serves as an instructional and operational resource for contractors and NJDOT personnel responsible for winter maintenance operations.

The guide provides detailed technical specifications and operational procedures for snow plowing across six highway categories: two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, multi-lane divided highways with raised medians and no drainage, multi-lane divided highways with depressed medians and drainage, and jughandles. For each configuration, the document specifies truck positioning, spacing intervals (typically 100 feet between trucks), overlap requirements (approximately 2 feet), and directional plowing sequences to ensure comprehensive snow removal from roadway surfaces to shoulder and gutter lines. Additional guidance addresses specialized roadway features such as switch-back curve ramps, which require power-reversible plows or graders for optimal efficiency. The standards emphasize progressive widening and sequential truck deployment to maximize operational effectiveness and safety during winter storm events.
