Gas prices near 31520

Brunswick is the mainland port city of the Golden Isles, laid out in an old colonial grid much like Savannah's, with the deep-water port and the marshes spreading out to the east. That layout matters for fuel hunting: the stations clustered downtown along U.S. 17 and Norwich Street serve in-town traffic, while the busier, more competitive pumps sit out near the I-95 interchanges a few miles to the west and northwest of the historic center.

Drivers heading over to St. Simons or Jekyll cross long causeways with no fuel once you leave the mainland, so this ZIP is effectively the last fill-up before the islands. Stations near the F.J. Torras Causeway and the Sidney Lanier Bridge approaches know they are catching beach-bound and resort traffic, and that captive position tends to keep their posted prices a notch firm compared with the interior of town.

Your better bets are usually the high-volume retailers along the U.S. 17 and U.S. 341 corridors, where steady local turnover and tighter competition keep credit prices honest. If you are about to merge onto I-95 for the long run between Savannah and Jacksonville, it is worth checking the in-town price before committing to whatever the ramp stations are posting that day.
