  • That’s cool and all, but the main reasons modern concrete structures don’t last are either:

    1. They’re full of steel reinforcement (because it would be unacceptably expensive to build structures relying entirely on compression the way the Romans did) and the steel deteriorates, or
    2. They become functionally obsolete regardless of the continuing stability of the structure.

    There are precious few things we build these days, aside from deliberate monuments, that we even want to last 100+ years to begin with. Even huge things like the Hoover Dam aren’t meant to be permanent on that kind of timescale.






  • I actually had a job for a while where I was responsible for the Changeable Message Signs (CMSs) on the freeways. So not quite a traffic reporter, but responsible for giving traffic advice to drivers in real time. You’re right, it was a reasonably interesting job.

    That said, other than making people aware of multiple-lane-closure wrecks in time to take an alternate route, there isn’t much “alleviating” that mere comments can do. The fundamental problem is that too many people are trying to use the roads at once because the system isn’t designed to facilitate alternatives to driving. Having some engineer on the TV every day saying “lobby your politicians for more funding for bikes and transit” might be a good thing, but wouldn’t exactly be “news.”
