History

Considering that, only a year after the highway was commissioned, the Miller County section of the highway was decommissioned, leaving the Brinson section of GA 310 as a double spur in Decatur County, ending at the Miller County line to the north and Lake Seminole to the south with the other section of the highway across the lake. In 1965, a new route was constructed in Miller County, extending from the GA 310 stub end north to Colquitt. However, oddly enough, this road did not become part of GA 310 for more than two decades to come. In fact, the extension to Colquitt was not completed until the early 1990s. Perhaps the consideration of decommissioning the highway was so strong that no action was taken for all that time.

When the Miller County section was commissioned, GA 310 was at maximum length, extending nearly 33 miles (53.1 km). This all changed, however, in 1995. That year, the 5.8 miles (9.3 km) dead end Yates Spring Road section south of GA 253 to Lake Seminole was decommissioned and the 3.5 miles (5.6 km) portion of the highway on the other side of the lake was changed to GA 97 Spur. Coinciding with that was the relocation of the northern end of the highway to Grow Street instead of connecting to U.S. 27 in downtown is now State Route 45 Connector on Northern Terminus of U.S. 27 and State Route 1.around the other major highways . However, the 2005 map shows GA 310 restored back to the former terminus! Such a shift seems highly unlikely, however
