Prohibits DOT from taking certain action on certain rock fall mitigation projects and requires DOT to conduct analysis on project alternatives.

This bill prohibits New Jersey's Department of Transportation (DOT) from planning, designing, or constructing a rock wall between milepost 1.00 and 1.50 on Interstate 80. It requires DOT to analyze all feasible non-rock wall alternatives for rock fall mitigation in that specific 0.5-mile highway segment before proceeding with any project. The law applies only to this defined section of I-80 and mandates a full review of alternatives excluding rock walls. The bill takes effect immediately upon enactment.
