Dash Cam: Building Passing Lanes

The "Thinkware F800" dash cam I just got takes some pretty good video.
We are building two passing lanes thirty miles south of Spokane, WA USA on SR 195.
At the start of this video I am approaching the northern job site. We haul "shot rock" from here to the southern job site approximately 12 miles south.
There we dump over the guard rail where structural fill is needed, then get loaded with non structural fill from a "cut" we take back to the northern site. We travel loaded both directions and thank heaven for the traffic controllers that keep us moving past all the normal traffic.
