T0777 Attachment 4 - Snow Plow Guide.pdf

This document is an NJDOT (New Jersey Department of Transportation) Snow Plowing Guide that establishes operational standards for snow removal services on state highways. The guide serves as a reference document for winter operations and is available on the NJDOT Intranet under Winter Operations.

The guide provides standardized plowing procedures for 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. Each configuration specifies truck positioning, spacing intervals (typically 100 to 500 feet between trucks), overlap requirements (approximately 2 feet between passes), and directional responsibilities. For example, on two-lane highways, Truck #1 guides on the centerline with the plow extending slightly into the adjacent lane; Truck #2 follows approximately 500 feet behind with a 2-foot overlap; and Truck #3 follows 100 feet behind Truck #2 to clean remaining areas to the gutter line. Additional guidance addresses specialized areas such as jughandles and switch-back curve ramps, with specific recommendations for equipment deployment and snow placement. These standards ensure comprehensive coverage, minimize gaps in plowing operations, and maintain maximum clear paths for traffic flow across all highway types within New Jersey's transportation network.
