A Southwest plane headed to Denver from Oakland early Saturday night slid off the taxiway shortly after landing.
Five crew members and 125 passengers were on board Flight 1905 as the Boeing 737 skidded off the taxiway moments after landing at around 5 p.m. Mountain time, said Southwest Airlines spokeswoman Katie McDonald
Passengers were bussed back to the terminal and those with connecting flights were accommodated, officials said.
One person aboard said she knew something was wrong, when she heard a strange noise.
"All of a sudden we heard a bunch of rumbling and the plane started to go sideways next thing we knew we were off in a ditch," said Teresa Penbrooke.
No injuries have been reported.
Officials have not said yet if weather played a role in the incident, but a cold weather system was moving through the area at the time and conditions were deteriorating.
There were freezing temperatures and about a quarter mile visibility.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
