I came across this interesting product for structural/geotechnical monitoring of cracks in 3 dimensions. Most crack monitors are designed for monitoring in 2 dimensions, this one can measure movement out of the plane of monitoring. I like that the markings are laser-etched so the simple device should last for a long time. Price is $40/each from Quality Plus Engineering, LLC.

I saw this video on the ADOT Facebook Page. The failure seems larger than what I though based on the photos from the ground. [Source: ADOT Facebook Page]
