Document Summary

This is the NJDOT Snow Plowing Guide, a technical operations manual issued by the New Jersey Department of Transportation. The document establishes standardized plowing procedures for state and local roadway maintenance operations across New Jersey's highway system.

The guide provides detailed operational standards for snow plowing activities across 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. For each configuration, the guide specifies truck positioning, spacing intervals (ranging from 100 to 500 feet between vehicles), plowing sequence, overlap requirements (approximately 2 feet between passes), and specialized procedures for roadway features including jughandles and switch-back curve ramps. The document includes technical diagrams illustrating truck placement and snow displacement patterns. Equipment specifications note that switch-back curve ramps are optimally plowed using power-reversible plows or graders, with alternative procedures provided when such equipment is unavailable. The guide is intended for field operators and supervisory personnel managing winter maintenance operations and serves as the standard reference document accessible through NJDOT's internal intranet system.
