Transport and commuting · The east Gwinnett roads
Getting around Dacula
Getting around Dacula is a surface-road story with one good express idea in the middle. US 29 and State Route 8 (Winder Highway) run through the center of town, State Routes 124 and 324 cross the Hog Mountain side, and I-85 sits a short drive west at the Hamilton Mill interchange. Most everyday trips stay on those four-lane and two-lane roads.
Transit is thin: no local bus reaches the city, and the practical option is the Xpress commuter route from the Dacula Park-and-Ride at Hebron Baptist Church, which connects to MARTA rail downtown. Every route, lot, and time below is verified; where something does not exist, this page says so plainly.
The roads
The crossroads grid the town actually runs on
US 29 Business and State Route 8, Winder Highway
The main road through downtown Dacula, and the one that carries the grocery, school, and errand traffic every day. Southwest it runs toward Lawrenceville; northeast it continues through the old town toward Auburn and the Winder side.
State Route 124
Runs through the Hog Mountain corner of the city and crosses State Route 324 just east of the old crossroads. It is the direct road southwest to Lawrenceville and northeast toward the Mulberry and Braselton sides of the county.
State Route 324
The connector that ties the Dacula area to the interstate: it runs from the Buford side, through Hog Mountain, to its eastern end at US 29 Business and State Route 8 in Auburn. It is also the fastest way to the Mall of Georgia corridor from the Hog Mountain side.
I-85, a short drive west
The nearest interstate access is the Hamilton Mill interchange, Exit 120, roughly ten minutes from downtown Dacula in light traffic. That is the on-ramp most Atlanta commuters use, and the reason the park-and-ride lots sit where they do.
The commutes
What the drives to the usual destinations actually take
Times below are published figures for normal, uncongested traffic on the roads Dacula actually uses. The weekday peak changes them substantially, and the Atlanta run is the one that everyone asks about first.
Downtown Atlanta
About 45 minutes
Roughly 37 to 40 miles via I-85. Published figures run 40 to 50 minutes in normal traffic; at the worst of the weekday peak, budget 75 minutes or more.
Lawrenceville
About 10 minutes
About 6 miles down State Route 124, with published figures around 10 minutes. The easiest drive in this guide, and the one county business actually uses.
Mall of Georgia corridor
About 25 minutes
Around 14 miles via the Buford side, with published figures near 26 minutes and 15 to 30 on the spread. The big retail and job anchor of the corridor, close enough to be routine.
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. A Dacula household commuting into Atlanta runs above that average by design.
Transit
The honest transit picture: one commuter route, no local bus
No Ride Gwinnett local bus reaches Dacula or the Hog Mountain area. The county's local routes serve the central and southern corridors of Gwinnett, and none of them extends to this eastern corner of the county. There is no ride-hail shuttle run by the county here either.
The commuter service that genuinely serves the city is Route 416 of the Xpress regional network, which absorbed Gwinnett County Transit's former express routes in June 2025. It runs weekdays from the Dacula Park-and-Ride and connects to MARTA rail downtown:
Xpress Route 416
Dacula to downtown Atlanta
Weekday service from the Dacula Park-and-Ride, with a stop at the Indian Trail lot along the way. Connects at the Civic Center MARTA station in downtown Atlanta.
Xpress Routes 413 and 414
Hamilton Mill to downtown and midtown Atlanta
Weekday routes from the Hamilton Mill Park-and-Ride, a short drive west at the I-85 interchange. Handy for the Mulberry side of the city and the addresses that face that way.
Dacula Park-and-Ride
At Hebron Baptist Church, on Hebron Church Road
The city's commuter lot, in the northeast corner of the church parking at 202 Hebron Church Road. Route 416 leaves from here on weekday mornings and returns in the evening peak.
Hamilton Mill Park-and-Ride
On Sardis Church Road in Buford, at the Hamilton Mill interchange
The larger lot on the western side of the city's orbit. Routes 413 and 414 leave from here on weekday mornings; it fills earlier than the Dacula lot.
Schedules and fares change with the season, and the June 2025 handoff to Xpress is recent enough that printed habits are worth re-checking. Confirm the current timetable before your first ride; both lots fill early on weekday mornings.
Rail and air
MARTA, Hartsfield-Jackson, and the local field
No MARTA rail line reaches Gwinnett County. The nearest station to Dacula is Doraville, the outer terminus of MARTA's Gold Line, roughly half an hour by car via I-85 in light traffic. For most Dacula riders, the rail part of a transit commute is the Xpress connection at the Civic Center station downtown instead.
Hartsfield-Jackson Atlanta International Airport is about 46 to 47 miles from town, typically around an hour in normal traffic and faster late at night. It is the hub airport for the region and the answer to "which airport" for most Dacula households.
For private and general aviation, the nearest public field is Gwinnett County Airport Briscoe Field in Lawrenceville, about fifteen minutes by car, a public-use municipal airport with a 6,000-foot runway.
The takeaway
Driving or transit, the honest answer for Dacula
- The Atlanta commute runs via the Hamilton Mill on-ramp and is the one that grinds: free-flow is about 45 minutes, the weekday peak is longer, and the worst mornings run past 75.
- The Lawrenceville and Mall of Georgia runs are the practical ones, ten and 25 minutes respectively, and they move against the heaviest Atlanta flow.
- Winder Highway through downtown backs up in the school and evening windows; the Hog Mountain side of the city is where the newer, wider roads sit.
- The Hebron lot is the weekday alternative: one bus, downtown by 8, MARTA on the other side. It fills early, and it only works five days a week.
- There is no fixed-route transit inside the city, and none is announced. The honest expectation is car dependence with a real express option at the lot.
