Just past the northeastern edge of Tunnel Hill is an interchange with Interstate 75 (I-75; Larry McDonald Memorial Highway).

[5][6] The next year, this segment's northern end was shifted to the northwest to travel from Villanow to US 41/SR 3 in Tunnel Hill.

[16][17] Later that year, the Whitfield County portion of the Villanow–Tunnel Hill segment of SR 2 had a "completed hard surface".

[19][20] By the beginning of 1948, all of SR 201 at the time, except for its northern terminus, had a "sand clay, top soil, or stabilized earth" surface.

The highway's northern segment was replaced by SR 2's new routing, thereby truncationg it to the western part of Varnell.
