Tennessee State Route 300
State Route 300 is a four-lane freeway in Memphis, Tennessee that runs from Interstate 40 to U.S. [Route 51 in Tennessee|U.S. Highway 51]. SR 300 is unsigned throughout its length except on mileposts. The exit signs on I-40 just refer to SR 300 as Exit 2A going to US 51 and Millington. SR 300 carries a speed limit. Local media sometimes refers to this short route as the "101 Connector", its former federal aid urban designation. The I-69 designation has been approved for the entire length of SR 300.
The route that is now SR 300 was originally envisioned as a freeway known as the Mud Island Expressway, which would have extended from the present-day eastern terminus across Mud Island to I-40 near downtown.
