2017-02-13 - Park City, UT - Triangle

Hello, So on February 13th 2017 I was driving home by myself from work. I worked in Heber City, Utah. The road from Heber to Park City, Utah, is rather dark (highway 40) and it's the only way to highway 80. It was later around 9:20ish and nobody was on the road with me. I noticed something odd as I was going to go over the bridge from 40 to 80 so, I slowed way down to about 20mph and looked up.

It was very, very low triangular shaped with a greenish white light underneath metal looking and it seemed to be floating. I had my window down and I did not hear any helicopter noises. It actually freaked me out. I grew up around helicopters and airplanes due to my father being in thr airforce and I had never seen anything like that. There is a military base near my home where I curently live so I wasn't sure what to think. I came home told my dad about it but he was stumped. (He still works on airplanes)

I don't think it was a drone bcecause it was rather large. I don't know why I didn't take a picture, but like I said it freaked me out and I wanted to get away from it. Thanks for your time.
