Requires underground structural assessment prior to commencing public highway or public transportation projects within close proximity to operating or retired mines.

This bill requires underground structural assessments before starting public highway or public transportation projects near operating or retired mines. It affects state transportation authorities like the Department of Transportation, New Jersey Transit, and the Turnpike Authority, as well as their contractors. The key mechanism requires entities to obtain guidance from the Department of Labor's mine safety section, conduct assessments if needed, and submit results within 10 business days. For high-risk sites, it mandates post-construction monitoring using techniques like elevation scans and ground-penetrating radar. The goal is to prevent subsidence-related damage, ensure public safety, and avoid infrastructure disruptions.
