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 and ice removal services on state highways. The guide serves as an instructional resource for contractors and NJDOT personnel responsible for winter maintenance operations across New Jersey's roadway network.

The guide provides detailed technical specifications and truck positioning standards for snow plowing operations across six distinct 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, multi-lane divided highways with depressed medians and drainage, and jughandles. For each configuration, the guide specifies truck sequencing, spacing intervals (typically 100 to 500 feet between trucks), overlap requirements (approximately 2 feet), and designated plowing patterns to ensure complete coverage from shoulder to gutter line. Additionally, the document includes standards for switch-back curve ramps, recommending the use of power-reversible plows or graders for optimal snow removal efficiency. The guide emphasizes progressive widening strategies and notes that when drainage and storage areas are available on raised medians, alternative formation patterns may be employed to enhance operational effectiveness.
