Crews have been able to rescue all of the people that were trapped in the Arch elevators for two and a half hours Saturday evening, reports CBS Station KMOV.
Fire Department spokesman Steve Simpson told a local television station that rescue crews treated two people. One was given oxygen and the other was diabetic. He didn't elaborate on their treatment.
"Everybody else seemed to be in good spirits, glad and relieved to be coming down," he said.
The people became trapped when trams on both legs of the arch stalled. Some people also were stranded at the top of the 630-feet high monument of stainless steel, where they were watching a fireworks show, broadcasters reported.
Around 11:30 p.m., light could be seen again through windows at the top of the arch. And a man trapped inside used his cell phone to call KSDK television and report that the trams were working again and people were being taken to the bottom.
Anxious relatives stood outside the popular tourist attraction as rescuers worked inside. Dozens of emergency vehicles surrounded the arch.
Firefighters and police did not immediately return calls from The Associated Press seeking comment. Calls to the Gateway Arch also were not immediately returned.
