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

This bill allows New Jersey municipalities to place free advertisements on bridges and railway overpasses within their borders that are managed by state transportation authorities (such as the NJ Turnpike Authority, South Jersey Turnpike Authority, or NJ Transit), subject to approval and safety rules. Municipalities must apply through a process established by the Department of Transportation, and ads must comply with existing restrictions - like not mimicking traffic signs, avoiding flashing lights, and not promoting private businesses - to ensure safety and prevent interference with traffic control. The bill also amends state law to exempt these municipal advertisements from requiring a permit under the Roadside Sign Control and Outdoor Advertising Act, provided they meet all specified conditions.
