The recent devastation in western North Carolina from hurricane Helene is truly mind-boggling. There is no doubt that it will be multiple years before the roads there are back to anything resembling "normal." I'm sure the death toll will also only go up from where it is now, which is heartbreaking. Watching on the news, one can't help but to feel utterly helpless.

One aspect of this ever-changing story that will be fascinating to watch will be how the North Carolina DOT chooses to repair the collapse of I-40:

In addition to the curved section shown above, a longer, straighter section also washed out, with the adjacent river coming perilously close to the road's edge. From a logistical perspective, it's going to be very interesting to see how they choose to fix this collapse. Is it better to cut into the neighboring rock and essentially shift the road away from the river's edge? Do you try to backfill the river somehow? I can only imagine the engineering challenges that await this repair.

A terrific YouTube channel to follow for this kind of content is Casey Jones - Professional Engineer. He often digs deep into stories such as this, providing his own insights as a certified civil engineer. The video below has some good footage of the damage the highway received, along with some brief commentary about the challenges ahead.
