I showed my husband the pictures, as he has 38 years experience in road construction. He said that we have been in that area many times and there's
been a "dip" in the road for years. Ie it was showing signs of instability at that point. He stated to me that it appeared to be a typical road
collapse, and that could be anything from the bedrock or base it was built on, to the built up layers they use to build up the road to the asphalt
surface.It may have been from seismic activity...we don't have all the answers yet. Many of the roads were built back in the 50s and 60s, and many
haven't seen alot of attention since. I'm not saying that this is just true in Arizona, but in many states. He also stated that this isn't really
that unusual for the type of area this road was built in. Mind you, this is just his opinion from all the years of his experience, working all over
the western US.
Now, for my personal take on this....WOW...what a mess. That clean up will take some time, once they stabilize the area, and figure out just why it
collapsed. I sure as heck wouldn't have been standing on the road...you got more guts than I do!
