History

SH 77 was originally proposed on August 21, 1923, as a route from Douglasville to Naples, replacing SH 1B.^[2] On June 24, 1931, SH 77 was extended southeast to Louisiana, replacing a portion of SH 47.^[3] On August 4, 1932, SH 77 was extended to SH 11 (now US 259). On March 11, 1935, SH 77 Spur was designated to Marietta. This would be cancelled on completion, but would be restored on April 19, 1937, as SH 245. On July 15, 1935, the section of SH 77 west of Naples was cancelled.^[4] On September 26, 1939, SH 77 was extended west to Commerce, replacing SH 260, but this plan was cancelled on January 14, 1941. On February 28, 1966, SH 77 was extended west over FM 2880 from US 259 to US 67.^[5]
