Several Gainesville residents gathered along Thompson Bridge Road on Monday morning and afternoon to wave signs and pass out fliers protesting plans to redevelop the Lanier Plaza shopping center. Citing concerns about traffic and environmental impacts, how the proposed project squares with the city’s 2030 comprehensive plan and what will become of the existing businesses in the shopping center, residents staked signs in the ground at Lanier Plaza urging passers-by to support their cause. “This is obviously something we don’t want,” said Vanessa Hyatt-Fugate, who lives in a neighborhood adjacent to the shopping center.
