SR 36/SR 126 then continue southeast to a y-intersection, where they turn onto Fort Henry Drive and become a divided highway.

The highway then passes through rural areas again, now paralleling I-81, to enter Blountville, where it has an intersection with SR 75.

SR 126 then passes through Walnut Hill before entering Bristol, coming to an end at an intersection with US 11W/SR 1 just south of downtown.

SR 126 was the original US 11W from Bristol to Kingsport until the late 1950s when the US highway was relocated 4 miles north of Blountville and paralleled Reedy Creek Road/Bloomington Pike Road, which bypassed Blountville and Sullivan Gardens.

[citation needed] The part known as Memorial Boulevard from Kingsport to Blountville is undergoing an widening project that will add more lanes and make the road safer for traffic.
