San Marcos drivers with a sweet tooth are about to get a new excuse to exit I-35. Swig, the Utah-born chain that helped turn TikTok-famous “dirty sodas” into a national habit, is moving into a drive-thru spot at 180 N. I-35. The brand is known for its customizable fountain soda mixes, sweetened with flavored syrups, fresh fruit and a splash of cream, and it has been rapidly franchising across the United States. New signage is already up at the site, although the company has not yet announced a firm opening date.
According to Community Impact, this will be Swig’s first location inside San Marcos city limits and will sit along the busy I-35 corridor. The outlet reports that the chain now operates more than 150 locations nationwide and that the San Marcos shop will bring Swig’s signature dirty soda lineup to local customers.
Where It Will Sit
Earlier this month, new Swig-branded signage went up on the former Salad and Go drive-thru at the 180 N. I-35 pad, signaling that the long-vacant site is finally getting a new tenant, as reported by MySA. Commercial real estate listings also now tag the address with a Swig label, backing up the local chatter, according to LoopNet.
What They Will Be Pouring
Swig’s menu centers on build-your-own dirty sodas, which start with a standard fountain soda and then layer in flavored syrups, fruit purees and various creams, with plenty of seasonal names, snacks and specialty twists in the rotation, according to Swig. For anyone who wants something lighter or more caffeinated than a traditional soda, the company also highlights Refreshers, which are water-based fruit drinks, and Revivers, which are customizable energy drink mixes.
Why Locals Should Pay Attention
Swig openings in Central Texas have not exactly been low key. New shops have been known to trigger long car lines and parking headaches, with operators rolling out cones, temporary signage and extra staff just to keep traffic moving, as reported in a dirty soda frenzy at Austin's first Swig. Those growing pains can be a mixed bag: they often boost visibility and foot traffic for neighboring businesses while creating short-term circulation issues for property managers and customers trying to get in and out.
For now, the company has not posted a firm opening date for the San Marcos drive-thru, according to Swig. Local coverage from Community Impact and future updates to Swig’s store locator are likely to be the best places to watch for a confirmed timeline. This story will be updated when the company announces an official opening date.
