That bridge is very, very well marked with lights flashing whenever a high truck approaches. Not all bridges even have the accurate height, sometimes being more than a half foot lower than marked. Many bridges have only two or three inches of clearance beyond the standard 13' 6" so even a pothole can bounce you into it. Speaking from experience.

Speedy,
And yet morons continue to hit the bridge with their trucks. Pathetic.

Storrow Drive in Boston has similar problems (trucks are supposed to stay off, but. . .).
You'd think it would be easy enough to put up stoplights, triggered by height sensors in well in advance of the bridge.
Notice the train crossing in one of the clips. I'm surprised that those impacts don't compromised the integrity of the tracks—or the bridge itself.

The page on the bridge provided by pRICE cUBE,
http://11foot8.com/, mentions the following:
So frequently do trucks crash into the 11-foot-8 clearance trestle, that the railroad company installed a crash beam in front of it. This massive steel I-beam bears the brunt of the impact, protecting the structure that supports this fairly busy railroad track. Believe it or not - they already had to replace the beam once!

They could you know, raise the bridge a little. There has to be another way around the bridge, so why not shut that road down for awhile and get the job done?

Probably easier to lower the road than to raise the bridge. Hard to re-grade the railroad tracks.
