Thanks, it is always interesting learn of new cases.

This particular area was difficult during the initial construction. Unfortunately, a lot of rock is available and the late Winter/early Spring sees a lot of this.

thank you TDAA for the great photo link!! did you see how some of the boulders are broken on pink veins?

say, emmgjld, can you say anything more about the construction? how close is it to the tunnel portal?

This is several hundred feet to the west of the tunnel. In one location you can see the end of the median divider. This location allows for enough room to shift traffic between EB and WB lanes.

Here is some info on the canyon:

This link shows the west end of the tunnel. In the pic of the hanging Lake Tunnel, you can see the electric sign and the crossover. This is the exact area of the slide.

Oops, I think that pic is actually the east end, but the layout is similar, and gives perspective of the slide vs. the tunnel location.
