(KSL News) -- A man is in critical condition this evening, after he walked into traffic on Interstate 80 this morning.
It happened just after 10 a.m. near the State Street off-ramp. Troopers say the man stepped out in front of an A-1 disposal vehicle... and was hit.
Sgt Phil Waters/Utah Highway Patrol: "FROM WITNESSES STATED HE WAS IN THE EMERGENCY LANE. HE WALKED OUT INTO THE CENTER LANE OF THE FREEWAY AND TURNED AND LOOKED AT THE TRUCK AND WAS STRUCK BY IT."
The man was flown to the hospital. Investigators say there was no car nearby, and they aren't sure why he was walking along the freeway.
And, they don't know who he is!
He's a white male in his late 30's, with curly brown hair, a beard, and a moustache.
He has a tattoo on his right arm and was wearing a green t-shirt, blue shorts, white sneakers, and a ball cap.
Investigators are asking anyone with information to call 887-3800.
