Route description
SR 320 is known as East Brainerd Road its entire length, and begins at an intersection with Lee Highway (US 11/64/SR 2) near the Chattanooga Metropolitan Airport. From here SR 320 travels eastward as a two lane road to traverse I-75/US 74’s Exit 3 interchange, where it widens to five lanes, including a center turn lane.[2] SR 320 continues eastward through the community of East Brainerd, before ending at a four way intersection with SR 321 just south of Collegedale.[3][4] TDOT has been working since 2015 to widen the route to four lanes to this point, and some of this project is already complete.[5] Although the state route designation ends at this point, a county maintained road also labeled as East Brainerd Road continues east to SR 317 in Apison, and some maps show this portion as part of SR 320.
