Arcadia 347 is a proposed 108‑acre, master‑planned mixed‑use development at 6150 Thompson Mill Road that straddles the Gwinnett–Hall county line, with roughly 72 acres reported on the Gwinnett side.¹ Translation: it’s big enough to affect how this corridor functions, not just what gets built on one site.

The project has been publicly framed as an “Avalon‑style” mini‑city: housing, retail, office, and hospitality organized around a walkable main‑street concept.¹ ²

A key adjacent move is now underway on the public side: Georgia DOT’s SR 211 widening project (Pinot Noir Drive to SR 347/Friendship Road)—about 1.6 miles—is described by GDOT as a four‑lane urban section with a raised median, shared‑use paths, and a bridge replacement over Duncan Creek.³ The January letting cycle also included a ~$38.5 million contract award for this segment, according to a Georgia CEO Network posting summarizing the State Transportation Board’s awards.⁴
