Green Valley Fire District firefighters extricate a victim from a vehicle after a collision early Friday morning when a vehicle hit a stopped SUV from behind, forcing it over the guardrail.

An SUV stopped on a freeway overpass was launched over a guardrail and onto the roadway below after being rear-ended by another vehicle early today in a three-vehicle wreck south of Tucson, officials say.

The driver of a southbound vehicle on I-19 then swerved into the median to avoid the SUV, said L.T. Pratt, a spokesman for Green Valley Fire District.

Two people were taken to the hospital after a crash that pushed one of the vehicles through the guard rail and onto the roadway beneath the overpass.

Two people were taken to Banner University Medical Center with injuries that are not life-threatening, he said. A third driver was treated at the crash scene.
