Allows municipalities to advertise for free on certain bridges and railways overpasses.

This bill allows New Jersey municipalities to display free advertising on bridges and railway overpasses located within their boundaries, specifically those managed by the Department of Transportation, New Jersey Turnpike Authority, South Jersey Turnpike Authority, or NJ Transit Corporation. Municipalities must apply through the Department of Transportation, adhere to strict safety and design rules (such as avoiding traffic-sign imitation, flashing lights, or private company promotions), and ensure ads don't interfere with traffic safety or existing signage laws. The bill prohibits advertising on Interstate/Primary System highways or in protected areas and amends existing law to clarify that such municipal ads require no fee or permit under specific conditions.
