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 and technical reference document for snow plowing services on state roadways rather than a formal contract award. The guide establishes standardized procedures and best practices for contracted snow plowing operations across various highway configurations throughout New Jersey.

The guide specifies detailed plowing standards for five highway types: two-lane two-direction highways, three-lane two-direction highways, four-lane undivided highways, multi-lane divided highways with raised medians and no drainage, and multi-lane divided highways with depressed medians and drainage. Each configuration details truck positioning, spacing intervals (typically 100 to 500 feet between trucks), overlap requirements (approximately 2 feet), and the sequence of plowing operations. Additional guidance covers specialized applications including jughandles and switch-back curve ramps. The standards mandate that Truck #1 initiate plowing from designated reference points (centerlines, lane lines, or median edges), with subsequent trucks following at specified distances and overlapping previously plowed areas to ensure complete snow removal to gutter lines. The document emphasizes efficient coverage and progressive widening where applicable, particularly for ramps requiring power-reversible plows or graders for optimal results. These operational standards apply to all contracted snow plowing services on NJDOT-maintained roadways during winter weather events.
