Milwaukee Marathon, Half Marathon & 5K Run Detours & Delays 2025
On Saturday, April 12, 2025 (subject to change without notice), riders should plan for delays and detours across the entire MCTS system from 6 a.m. until 1 p.m. Numerous streets and intersections across Milwaukee will be closed or partially closed for the Milwaukee Marathon, Half Marathon & 5K Run.
Because many MCTS routes intersect with the marathon course or connect with routes that do, plan for possible significant delays on all MCTS routes while the marathon is taking place.
Please use Real-Time on our website or in the Umo app to avoid long waits at your stop and give yourself extra time to get to your destination.
