A driver who struck a tree along Interstate 12 was airlifted to a hospital following a Sunday evening wreck in Denham Springs, an emergency medical spokesman said.

The crash happened just after 6 p.m. near the interstate's exit onto Range Avenue, said Justin Cox, a spokesman for Acadian Ambulance Service. 

A medical helicopter transported the patient whose condition wasn't immediately known.

Authorities closed the eastbound lanes near the exit and advised drivers to take an alternate route.
