ADCX Rob posted:The trucks in the 11foot8 videos are hitting a crash beam erected just before the bridge, placed to give one last visual warning(brightly painted yellow with warning verbiage) and to protect the bridge itself. "This massive steel I-beam bears the brunt of the impact, protecting the structure that supports this fairly busy railroad track."
I put a couple of them in during the first 6 yrs working for the state on a county bridge crew. We called them "Head Ache bars". We'd put them approx. 20-40' before the bridge.
Look at the video, 0.27, you'll see the bridge floor beam move up a little, not good.
