SR-343 begins at an intersection with US-25E south of Morristown and north of White Pine and is called Old US Highway 25E. It heads north and has an interchange with SR-160 and continues north through a commercial area/retail area and into downtown Morristown. After intersecting with SR 160, TN SR 343 becomes known as South Cumberland Street. There, SR-343 has an intersection with US-11E and SR-66 at two separate intersections. At the SR-66 intersection, the name changes to North Cumberland Street and then travels north to an intersection where the Cumberland Street designation comes to an end and it becomes Buffalo Trail, the route continues north under this name and ends at US-25E on the north side of Morristown, just 0.5 miles (0.80 km) from the Hamblen–Grainger county line.

And for traffic going northbound on US-25E traffic must turn on a short side road called South Cherokee Park Road and for traffic on SR-343 wanting to go southbound US-25E must also use the side road.
