Friday, July 21, 2017

Hop aboard in this one-minute clip showcasing some of the testing underway for LRV 4. This particular test focused on vibrations and ride quality.

During subway closure, a bus bridge will operate between Embarcadero Station and St. Francis Circle, making stops at subway stations. There will still be surface train service outside of the Muni Metro subway. Please plan extra travel time when taking Muni during subway closures.
