Atlanta's first real bus rapid transit line finally opened — a year late and roughly double its original $58M budget, with several stations still just temporary stops.

MARTA opened phase one of the Rapid A-Line on April 18, 2026 — metro Atlanta's first true bus rapid transit line, running mostly in dedicated lanes with upgraded, transit-signal-priority traffic signals on a five-mile route between the Five Points/Georgia State downtown core and the Atlanta BeltLine's Southside Trail. The line's construction cost roughly doubled from an original $58M estimate to about $123M after undocumented and shallow utility lines were found mid-excavation, and the opening slipped a year from an original summer-2025 target; at the April launch several of the 14 planned stations were still unfinished and served by temporary stops, with full completion (offboard fare payment, real-time information, level boarding at all stations) due in a second phase in fall 2026.

🎓 Lesson

Atlanta's first bus rapid transit line is a case study in why BRT budgets blow past their original numbers: undocumented utility lines under an urban corridor turned a $58M project into a $123M one, and pushed the opening back a year.
