the roadway that would eventually become us 27 bus./sr 1 bus. was established at least as early as 1919 as part of sr 1. in the first half of 1936, this segment had a "completed hard surface". between the beginning of 1953 and the 1960, sr 1 was routed on a more direct path between amsterdam and attapulgus, with a "soil surface". in 1989, an eastern bypass of attapulgus, designated as sr 831, was proposed from east-southeast of the city to north-northwest of it. in 1995, us 27/sr 1 was shifted onto this bypass. its former path was redesignated as sr 1 bus. between the beginning of 1996 and the beginning of 2011, us 27 bus. was designated on the path of sr 1 bus.
