T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the NJDOT Snow Plowing Guide, issued by the New Jersey Department of Transportation. It serves as an operational manual for snow plowing services across New Jersey's highway system rather than a formal contract award document.

The guide establishes standardized plowing procedures for different 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 medians and depressed medians with drainage. For each configuration, the document specifies truck placement, spacing intervals (typically 100-500 feet between trucks), overlap requirements (approximately 2 feet between passes), and sequencing protocols. Additional guidance covers specialized areas such as jughandles and switch-back curve ramps, with specific recommendations regarding plow positioning, direction of snow movement, and optimal equipment types for efficient snow removal. The procedures emphasize maximizing clear path coverage while minimizing thawing and refreezing cycles through coordinated multi-truck operations and progressive widening techniques where applicable.
