State Route 300 (abbreviated SR 300) is a four-lane controlled-access expressway inside of Memphis, Tennessee that goes from Interstate 40 to 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 55 mph (89 km/h) speed limit. Local media sometimes refers to this short route as the "101 Connector", its former federal aid urban designation (U-101 connector).[1] 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.
