T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the NJDOT Snow Plowing Guide, published by the New Jersey Department of Transportation. It serves as an operational manual for snow plowing services on state highways and roads within New Jersey.

The guide establishes standardized plowing procedures for various 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 or depressed medians. The document specifies truck positioning, spacing intervals (typically 100-500 feet between trucks), overlap patterns (approximately 2 feet), and directional plowing protocols. For two-lane highways, three trucks operate with specific spacing and overlap requirements. For three-lane highways, up to four trucks may be deployed. Multi-lane divided highways employ similar truck sequencing with provisions for additional lanes as needed. The guide also addresses specialized conditions including jughandles and switch-back curve ramps, with recommendations for equipment type (power-reversible plows or graders preferred for curve ramps). All procedures emphasize maximizing clear path coverage while minimizing refreezing cycles and ensuring efficient cleanup operations.
