T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the New Jersey Department of Transportation (NJDOT) Snow Plowing Guide, which establishes standardized operational procedures for snow removal services on state highways. The guide provides detailed specifications for snow plowing operations across various highway configurations and conditions.

The guide outlines snow plowing standards for five primary 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. Each configuration specifies precise truck positioning, spacing requirements, and overlap standards to ensure complete snow removal from roadways to shoulder and gutter lines. For example, on two-lane highways, Truck #1 guides on the centerline with the plow extending slightly into the opposite lane, Truck #2 follows approximately 500 feet behind with a two-foot overlap, and Truck #3 follows approximately 100 feet behind Truck #2 to clean remaining areas to the gutter line. Additional guidelines address specialized areas including jughandles and switch-back curve ramps, with specific instructions for equipment deployment and cleanup procedures. The guide includes detailed diagrams illustrating truck positioning and spacing for each highway type to ensure consistent, efficient snow removal operations across NJDOT's maintenance network.
