N-Swimmer - CLEARLY, all the science is well beyond me. BUT, absent wind in the requisite direction, is it possible to do anything to increase the rate at which the ice falls?I'd go slow for two reasons.
1. Minimize the addition of kinetic energy to the bridge structure, thereby avoiding a possible increase in the rate at which the ice is falling.
2. Increase the odds that I could stop in time to avoid falling ice that I observe ahead of me while crossing the bridge.
All's I can say is that when it snows and "ices" hereabouts, it get us all pretty excited!I see two factors here:
#1. Going faster would possibly "shake" the bridge, thus resulting in some Ice being jarred loose.
#2. IF there was Ice around, my bet is that there was ICE on the road surface of the bridge (That tends to be the case with almost ALL bridges--they tend to hold water and ice longer, due to the construction). As such, "going slow" over potential ice pockets, is likely a wise choice.
But, I have no actual knowledge of the Bridge in question, or the environmental conditions.
A quick Third Point: In cases such as this, I tend to trust the Police, as they are likely privy to a lot more knowledge about the situation.
Tell me about it.All's I can say is that when it snows and "ices" hereabouts, it get us all pretty excited!
Mr. Fair,Yesterday up here in the PNW, the Tacoma Narrows Bridges were shut down, because of the danger of falling ice. These bridges are a major thouroughfare, so this is a big deal. Anyway...one of the backed-up cars was carrying a woman on her way to the hospital to have her broken wrist set. The police allowed this car to cross.
News reports say the car crossed at a "safe pace" of 30MPH (speed limit is 60). What would YOU have done? I would've gone 60+ to minimize my exposure too falling ice, even as if I'd encountered any, I'd have done so at twice the speed.
What do the math/physics say about this one?
When I fought forest fires for the DNR during my high school and college summers, we were caused to "endure" a several days-long defensive driving course. I didn't realize it then, but that class has stood me in good stead, ever since.anecdotally I'd say..the faster you're going at point of impact..the greater the potential for injury..
fer example..if a deer crosses my path on the highway and I hit it at 30.... likely my bumper..hood..etc takes a beating...
if I hit it at 60 or better...it's likely crushing the front end and making its way on through the winshield...in a gory spray of red....
Phil. analyses anecdotally... and has seen this happen in PA.. highboy pickup v deer in road at 65+..... not good.
