A slate of recommended projects aimed at improving Gainesville’s transportation picture now has a price tag: $235.2 million. Norcross-based Pond & Co., the city’s consultant on a transportation master plan, presented a list of projects based on three time frames, or tiers — 2013-20, 2021-30 and 2031-40 — to a focus group Thursday night at the Fair Street Neighborhood Center. The focus group, made up of city residents charged with giving a nongovernmental perspective to the plan’s development, suggested moving some projects around and, in some cases, making them a higher priority.
