According to the video’s description, this is in Lillooet, BC to Gold Bridge.

The roads are treacherous with lots of tight turns and blind corners. There are also steep drop offs and no barriers.

Video’s Description:

It starts at the beginning of Bridge River Rd., where I had to maneuver onto a one lane bridge with less than 6″ of clearance on either side, and onwards from here. This is where Bridge River Rd. ends and Carpenter Lake Rd. begins with this test of trucking skills. Look for the pickup coming uphill, you can’t see it but the driver’s eyes went wide as saucers.-lol

At the bottom of the switchbacks there is a large cave not visible. You can see the cave in the video I took of my drive up this set of switchbacks after I unloaded and was homeward bound. Given the history of the area I would not be surprised to learn it was occupied at one time by early Native Indians.
