The recent collapse of a major freeway bridge in Washington State has raised concerns about U.S. infrastructure—and with good reason. According to a 2011 report from Transportation for America (the latest of its kind), nearly 70,000 of the nation’s bridges are considered “structurally deficient.” That means that one or more of their crucial components—the deck, where cars, trucks and people cross; the superstructure, which supports the deck; and the substructure, which supports the superstructure from the group—has received a rating lower than four from the Federal Highway Administration, on a scale of zero to nine. They’re technically still safe to drive across, but need to be monitored closely. (The Washington bridge was actually classified as ”functionally obsolete,” a level better than “structurally deficient.”) Here, a sampling of those risky bridges, ranked by average daily traffic.
You might want to do some fact checking when citing an old source.
The replacement of the 695 bridge over MD26 (Liberty Rd) was completed last year.
The 695 bridge over Millford Mill is being replaced this summer.
Baltimore County/Harford County line US40 both directions at the Gunpowder...that is a bridge diaster waiting to happen.
Isn't it wonderful that we are pouring billions into other countries while our own infrastructure is crumbling and there is no money to repair what can be death and suffering to our own? Where are we going??
A big earthquake, or Mt Rainier (volcano) popping its top in a big blast, will cripple Washington and Oregon infrastructure like nothing else -- short of nuclear war.
And no amount of planning and cash set aside to improve engineering, will strengthen infrastructure enough to withstand nature. Japan's acclaimed emergency preparedness, proven so weak when disaster actually occurs, proves that.
Nature decides who wins, who loses and who cares.
Finally somebody realizes that Nature is our true enemey. Everything else (including human induced climate change) is just a historical footnote.
@RudyHaugeneder All sorts of things can go wrong. It's a good idea to try to forestall the ones which we can predict, rather than to throw up our hands in impotence. We cannot predict just when a volcano might erupt, and we cannot forestall that. But we can inspectr bridges and other infrastructure to determine whether they are serviceable, and act accordingly.

@MustGoFishin Yeah, I was shocked that significant bridges were not on the list. In Maryland there is the 50 or so year old Bay Bridge, in Boston the million year old Tobin Bridge, in NYCity there are tons of ancient bridges, also in Chicago just about every bridge looks like a catastrophe waiting to happen. Most of the bridges into Canada from Detroit eastward to Lake Ontario look like a good wind would take them out. All of these would be extremely expensive and time consuming to replace and the effect on local commerce and commuting would be a nightmare. This is where we should be spending money, not the MIC and wars on drugs and terrorists.
@MustGoFishin Where did you get that definition from ? And what about a structure where the fall is 19 feet ? Is that a bridge or an overpass ?
