T0777 Attachment 4 - Snow Plow Guide.pdf

This document is the NJDOT (New Jersey Department of Transportation) Snow Plowing Guide, which establishes standardized operational procedures for snow and ice removal services on state roadways. The guide provides technical specifications and best practices for contractors performing winter maintenance operations across New Jersey's highway system.

The guide details plowing standards across five 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, and multi-lane divided highways with depressed medians and drainage. For each configuration, the document specifies truck positioning, spacing intervals (typically 100-500 feet between vehicles), overlap requirements (approximately 2 feet), and directional plowing sequences to ensure complete snow removal from travel lanes to shoulder or gutter lines. Additional standards address specialized areas including jughandles and switch-back curve ramps. The procedures prioritize maintaining maximum clear paths for cross-traffic and efficient cleanup operations through coordinated multi-truck sequences. The guide emphasizes that power-reversible plows or graders are most effective for complex configurations such as switch-back ramps, with recommendations for alternative equipment when specialized machinery is unavailable.
