The tree is plainly visible (when driving uphill) right below #6.
The highway used to cross a bridge and go through tunnel 4 and to the "Blinking Light" at the old intersection. The road was straightned out and the intersection improved shortly after the Casinos led to increased traffic. I suspect it is now A CDOT storage shed.
THe tree is really big. It would take a crew of several guys a few hours to remove.
the section is commercially run, so they will deal with it for sure.
