I see a number of Dunning-Kruger drivers in this thread. This was apparently at night, in the rain, in an unlit area, and on a route the driver was unfamiliar with. There was no barricade or warning that anything was wrong. In those conditions, I think it's a bit disingenuous to blame this on the driver in any way. That bridge was a deathtrap waiting to happen.
As a side-note, I also know from personal experience how !@#$ hard it is to get a change through to Google Maps. The name of the park across my house was listed incorrectly. I tried for many years to get Google to update the name. Finally, the city took over management, and had an official website with photos showing the name of the park. So after well over a decade of trying (once every few years), I got the name of the park changed appropriately. I can only imagine the request to mark this bridge as broken was met with the same responsiveness.
