T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the New Jersey Department of Transportation (NJDOT) Snow Plowing Guide, which provides standardized operational procedures for snow and ice removal services on state highways. The guide establishes best practices and performance standards for contractors and NJDOT personnel responsible for winter maintenance operations across New Jersey's roadway network.

The guide details truck positioning, spacing, and overlapping requirements for snow plowing operations across five highway configurations: 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. For each configuration, the document specifies the sequence and spacing of plowing trucks, with typical intervals of 100 to 500 feet between trucks and overlap of approximately 2 feet to ensure complete snow removal and clearing to the gutter line. Additional standards address specialized applications including jughandles and switch-back curve ramps, with recommendations for using power-reversible plows or graders for maximum efficiency. The guide establishes that progressive widening and strategic truck deployment minimize operational delays while ensuring comprehensive roadway clearance during winter weather events.
