The South Dade TransitWay has been a bus-only road since February 1997; what opened on 27 October 2025 was its data layer. Miami-Dade's Department of Transportation and Public Works rebuilt the 20-mile corridor with 14 fare-gated stations — off-board payment by EASY Card, contactless bank card or QR ticket, level boarding, real-time arrival displays — plus crossing gate arms and traffic signal preemption meant to hold a green for peak-direction express buses. On the first morning the preemption did not work: the county blamed test programming still in the system, unauthorised vehicles on the busway and drivers blocking intersections, and announced a 90-day optimisation period. The county had chosen this over rail, its Transportation Planning Organization selecting BRT as the locally preferred alternative on 30 August 2018 against a far costlier Metrorail extension. The line still does not enter the City of Miami: it runs entirely through southern Miami-Dade and ends at Dadeland South in unincorporated Kendall, where riders transfer to Metrorail for downtown.
📊 Impact
The FTA's Small Starts profile justified its $100M share on a forecast of 14,700 daily linked trips in the 2018 base year, rising to 20,600 by 2040. The county's own ridership report for December 2025 counts 5,240 average weekday boardings on BRT route 601 and 4,113 on the parallel local route 602 — 9,353 together, against 7,950 on the three routes (34, 38, 39) the conversion discontinued. Boardings and linked trips are different units, a linked trip often covering more than one boarding, so the distance to the forecast is at least this wide. Route 601 slipped 4.2 percent from November to December 2025, and Dadeland South Metrorail alone supplied 2,073 of its 5,240 weekday boardings.
🎓 Lesson
A rebuilt corridor is only as fast as the signals it is allowed to hold: Miami-Dade bought preemption hardware and gate arms and then found on day one that the binding constraint was signal programming and enforcement against drivers in the busway, not equipment. And a line that ends at someone else's rail station inherits that station's reach rather than its own — two fifths of the BRT's boardings happen at the transfer point.
