The injured were taken to Kendall Regional Medical, a level one trauma center nearby.
Two of the individuals are in critical condition and the other eight are in stable condition, Dr. Mark McKenny told reporters.
“Both (patients in critical condition) were operated on emergently,” McKenny said.
Injuries range from abrasions to broken bones, McKenny said.
Six to 10 people were killed in the collapse, U.S. Senator Bill Nelson of Florida told TV station CBS Miami.
Emergency personnel with sniffer dogs searched for signs of life amid the wreckage of concrete and twisted metal that rained from the collapsed structure and crushed vehicles on one of the busiest roads in South Florida.
At least eight vehicles were trapped in the wreckage of the 950-ton bridge and at least 10 people have been transported to hospitals, officials and doctors told news conferences.
Witnesses told local media the vehicles were stopped at a traffic light when the bridge collapsed, and authorities said there still may be more vehicles trapped underneath.
