Transport and commuting · The I-85 corridor
Getting around Suwanee
Getting around Suwanee is an interstate story with a walkable middle. I-85 runs along the town's east side with the main exit at State Route 317, the I-985 split just north, and the Mall of Georgia interchange beyond it. Downtown Suwanee around Town Center is the one place you can leave the car, and the rest of the town runs on a handful of state highways.
Transit is better than most Gwinnett addresses: a real local bus, Ride Gwinnett's Route 50, runs through the center of town, and the region's commuter express network is minutes away at two park-and-ride lots. Every route, lot, and time below is verified; where something does not exist, this page says so plainly.
The roads
The interstates and the highways that frame the town
I-85
Exit 111 at State Route 317 is Suwanee's main interchange, and the town's front door for Atlanta trips. Exit 113, just above the town line, is where I-985 splits off toward Gainesville, and Exit 115 at State Route 20 puts the Mall of Georgia about a mile from the city. A new half-diamond interchange at McGinnis Ferry Road is under construction on the south side.
State Route 317, Lawrenceville-Suwanee Road
The town's Main Street, running from the I-85 interchange through downtown and on south toward Lawrenceville. It is the road most school, pool, and plaza trips touch, and the one the morning peak backs up on.
Buford Highway, US 23 and State Route 13
Runs through the western side of town and meets Lawrenceville-Suwanee Road near the downtown core. North it becomes the Buford frontage, south it points toward Duluth and the Perimeter.
State Route 20, one exit north
Does not cross Suwanee itself, but its interchange at I-85 Exit 115 is the mall corridor, a few minutes north on the interstate. For Buford Drive errands, the quick answer is I-85 to Exit 115 or the surface run up Buford Highway.
The commutes
What the drives to the usual destinations actually take
Times below are published figures for normal, uncongested traffic on the I-85 corridor and the state highways. The weekday peaks change them substantially, and the Atlanta run is the one that everyone asks about first.
Downtown Atlanta
About 40 minutes
Roughly 33 to 34 miles via I-85 south. Published figures run 35 to 40 minutes in normal traffic; the morning peak stacks up to 45 minutes and more.
Mall of Georgia corridor
About 15 minutes
About 7 to 8 miles north, with published figures in the 12 to 15 minute range via I-85 or Buford Highway. The effortless commute in this guide.
Lawrenceville
About 20 minutes
About 9 to 10 miles down State Route 317, with published figures from 16 to 23 minutes. The county business run, straight down the road Suwanee was built on.
For scale: the average one-way commute in Gwinnett County runs about 33 minutes across all workers, per the U.S. Census Bureau's American Community Survey.
Transit
What actually runs: one local bus, two commuter lots nearby
Ride Gwinnett's local Route 50 is the only fixed-route bus in the city, and it is a real one: it runs through downtown Suwanee at Town Center, connecting the Suwanee side of the county to the Mall of Georgia, Exchange at Gwinnett, and Coolray Field. It does not reach the subdivisions off the main corridors.
No Xpress commuter route stops inside Suwanee itself; the park-and-ride lots sit at the edges. Sugarloaf Mills Park-and-Ride is a few minutes southwest, and the I-985 / State Route 20 lot in Buford is a few minutes northeast. Both feed the Xpress weekday express routes into downtown and midtown Atlanta, connecting with MARTA rail at the Civic Center and Arts Center stations. The Xpress network absorbed Gwinnett County Transit's former express routes in June 2025.
For rail without a bus: the nearest MARTA station is Doraville, the outer terminus of the Gold Line, about half an hour south on I-85 in light traffic. Most riders find the Xpress connection downtown more direct.
Schedules and fares change with the season. Confirm the current timetable before your first ride; the lots fill early on weekday mornings.
Rail and air
MARTA, Hartsfield-Jackson, and the local field
No MARTA rail line reaches Suwanee or any other Gwinnett address. The nearest rail station is Doraville, the Gold Line's outer terminus, about half an hour by car in light traffic; from there the line runs into downtown Atlanta and on to the airport.
Hartsfield-Jackson Atlanta International Airport is about 40 to 43 miles from town, roughly 50 minutes to an hour in normal traffic. The route uses the downtown connector, so the earlier the departure the better.
For private and general aviation, the nearest public field is Gwinnett County Airport Briscoe Field in Lawrenceville, about twenty minutes by car, a public-use municipal airport with a 6,000-foot runway.
The takeaway
Driving or transit, the honest answer for Suwanee
- The Atlanta commute runs down I-85 and is the one that grinds: free-flow about 40 minutes, the weekday peak longer, and the worst mornings are the ones that make people look at the lots.
- The Mall of Georgia and Lawrenceville commutes are the practical ones, 15 and 20 minutes respectively, and they move against the heaviest flow.
- Suwanee is one of the few Gwinnett towns with a bus through its center, and the express lots are minutes away on both sides of town. The rail connection is the point: Xpress routes meet MARTA downtown.
- School traffic concentrates at the interchange and along State Route 317 in the drop-off and pickup windows.
- Downtown Town Center is genuinely walkable, the one place in Suwanee where the car can stay parked.
