Tennessee State Route 373

SR 373 begins in Maury County at an intersection with SR 50 a few miles southeast of Columbia. It heads south as Culleoka Highway through farmland as a two-lane highway to pass through Culleoka, where it makes a sharp turn to the east. The highway winds its way east through more hilly terrain for a few miles to cross into Marshall County.[2] SR 373 winds its way through rural hilly countryside for several more miles as Mooresville Highway, where it has an interchange with I-65 (Exit 32) and widens to a four-lane undivided highway, before entering Lewisburg at an intersection with SR 417 (W Ellington Parkway). The highway becomes W Commerce Street and passes through neighborhoods for several miles before entering downtown. SR 373 then comes to an end at the courthouse square at an intersection with US 31A Business/US 431 Business/SR 11/SR 50 (2nd Avenue/E Commerce Street).[3][4]

The entire route of SR 373 was originally designated as State Route 50A (SR 50A). It has since been renumbered, as many of Tennessee's alternate routes were, to SR 373.
