Bridgehunter has been down for 3 weeks, I guess.
When James Baughn passed away (unexpectedly), he didn't leave any instructions as to how to keep the site up and running.
The folks who now maintain the site (Historic Bridge Foundation) knew a day would come in which the current Bridgehunter site would be unsustainable and a new site was being worked upon. I guess that crash came sooner than they expected.
