This is a clever thing to do, download an app and when you are rolling over a bridge use the built in accelerometers to measure the bumps and vibrations.
Pretty neat.
But I think you would want to continue the traditional inspections as well, at least until the tech proves out for about 20 years. Would hate to have a bridge fall down because the bridge rulers decided to depend on something that didn’t do a good job.
And of course, we don’t want to anger the bridge inspectors union.
