Document Summary

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

The guide details specific plowing protocols for five highway types: 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. Additional guidance covers specialized areas including jughandles and switch-back curve ramps. For switch-back curve ramps, the document recommends using power-reversible plows or graders to minimize thawing and refreezing cycles. The standards are designed to ensure comprehensive snow removal from traveled lanes to shoulder and gutter lines while maintaining safe traffic conditions during winter weather events.
