Interstate 985 (I-985) is a 25.01-mile-long (40.25 km) Auxiliary Interstate Highway in the northeastern part of the U.S. state of Georgia. It begins at an interchange with I-85 (which also serves as the southern terminus of SR 365) on the southeastern edge of Suwanee and continues northeastward to the city of Gainesville. I-985 is also known as the Sidney Lanier Parkway and is also designated as unsigned State Route 419. The roadway was designated as I-985 in 1985.
I-985 and SR 365 are concurrent for I-985's entire length, but only the I-985 signs are displayed. I-985 is also concurrent with US 23 from exit 4 northward.
I-985 is the highest-numbered spur route of a north-south Interstate, and is second only to I-990, which serves the Buffalo metropolitan area.
In Gwinnett County, I-985 begins concurrent with SR 365 at an interchange with I-85 on the southeastern edge of Suwanee. The two highways head northeast to Buford, at an interchange with US 23/SR 20 (Buford Drive N.E.). Here, US 23 joins the concurrency of I-985/SR 365.
