Interstate 985 (I-985) is a 24.04-mile (38.69 km) long auxiliary Interstate Highway in Georgia. It begins at Interstate 85 near Suwanee and continues northward to the north Georgia city of Gainesville. I-985 is also known as the Sidney Lanier Parkway and is the unsigned State Route 419.

I-985 and SR 365 currently run concurrently — both routes end at the interchange with I-85 near Suwanee — but only the I-985 signs are displayed. I-985 also overlaps U.S. Route 23 from exit 4 northward; US 23 was moved onto the Interstate once it was completed.

I-985 is the highest-numbered spur route of a north-south Interstate, and is second only to Interstate 990, which serves the Buffalo metropolitan area.

Route description

I-985 heads northeast from the southern terminus at I–85, towards Gainsville. Southeastern of Gainsville I–985 has an interchange with U.S. Route 129. Then I–985 has an interchange with State Route 369, this interchange is also the northern terminus of I–985. [2]

The speed limit is 70 mph (113km/h) except north of exit 22 where the speed limit drops to 65 mph (105 km/h). After exit 24, I-985 ends, and the freeway becomes a four-lane highway with at-grade intersections.

History

The highway was built in the mid 1960s as State Route 365; it was given the I-985 designation in 1985.
