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 lafayette area. between october 1929 and june 1930, a portion in the southern part of lafayette had a "completed hard surface". by the end of 1930, us 41w was designated on sr 1 from rome to lafayette. by the beginning of 1932, a portion of us 41w/sr 1 in the northern part of the city had a completed hard surface. by the end of 1934, us 41w was decommissioned, and us 27 was designated on the entire length of sr 1. nearly 50 years later, an eastern bypass of lafayette, designated as sr 730, was proposed from southeast of the city to north-northeast of it. in 1988, us 27/sr 1 in the area was shifted eastward, onto the path of sr 730. its former path through the city was redesignated as us 27 bus./sr 1 bus.
