Power is back at US Bank Plaza downtown.
Ameren officials say it should be business as usual today after a 36-story downtown office building was evacuated yesterday because of an underground transformer fire.
Ameren officials say the transformer was inside a vault under a sidewalk at 7th Street and Locust.
Fire crews rescued at least ten people from elevators. No injuries were reported.
An underground electrical fire has forced the evacuation of a building in downtown St. Louis.
Fire crews are on the scene at 7th and Washington. Images show thick smoke pouring out of grates on the street. Tenants of some other nearby buildings are not being allowed to leave.
