T0777 Attachment 4 - Snow Plow Guide.pdf

This is the NJDOT Snow Plowing Guide, a technical reference document issued by the New Jersey Department of Transportation for winter operations management. The guide establishes standardized procedures and operational protocols for snow plowing and spreading services across New Jersey's state and local roadways.

The document provides detailed technical standards for snow plowing operations across various 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 and depressed medians. Standards specify truck positioning, spacing requirements (typically 100-500 feet between successive trucks), overlap specifications (approximately 2 feet between passes), and directional movement patterns to ensure comprehensive snow removal and efficient coverage. Additional guidance addresses specialized applications including jughandles and switch-back curve ramps, with recommendations for equipment selection and operational approaches. The guide emphasizes that these standards can be found on the NJDOT Intranet under Winter Operations and serve as best practice recommendations for contractors and department personnel responsible for maintaining roadway conditions during winter weather events.
