Route description

Spalding County

Southern terminus in Griffin

SR 155 begins at an intersection with US 19/US 41/SR 3/SR 7 south of Griffin, in Spalding County. This also marks the southern terminus of US 19 Bus./US 41 Bus., which travel concurrently with SR 155 to the northeast to an intersection with SR 16 in the central part of the city. They cross a Norfolk Southern Railway until SR 155 departs to the east. It heads northeast, and turns north on McDonough Road. It heads northward and enters Henry County.^[1]
