House Bill 1739, also known as Senate Bill 1772, amends Tennessee Code Annotated to establish a framework for the enforcement of traffic laws on designated private roadways within the West Tennessee megasite. The bill introduces a new section, 64-9-116, which defines "designated private megasite roadway" and allows local law enforcement agencies to enter into written agreements with the authority overseeing the megasite. These agreements will enable sworn peace officers to enforce traffic laws on these private roadways, provided that the roadways are not dedicated to public use and are properly identified in the agreement.

The bill outlines specific requirements for these agreements, including the need for approval from the authority's board and the local governing body, as well as the installation of traffic-control devices that comply with state standards. It clarifies that entering into such agreements does not create public access rights or transfer ownership responsibilities to governmental entities. Additionally, the bill specifies that private security personnel are not granted law enforcement powers under this new provision. The act is set to take effect upon becoming law.
