KCBS_740 SAN FRANCISCO (KCBS) — Some BART riders had an unusual reason for a longer than usual commute Monday morning.

BART officials said that around 9am, a woman’s shoe got stuck on one of the escalators at the Embarcadero station, according to the San Francisco Chronicle.

The woman wasn’t hurt, but officials did shut down the escalator. Because of that commuters headed to a second escalator, which soon became overloaded, causing officials to shut it down as well.
