Around here they have both ground off old asphalt under bridges before repaving, and lifted bridges by cutting the columns, jacking up the bridge, and rebuilding the columns.

Grind the road down too much and they need to add more drainage. So cost goes up pretty quick.

For the price of a new bridge they could run a pump 24/7

Why can't you just dig the road surface down a few inches?

If you'll notice the speed limit sign, it's 70, so it would have to have a very gradual lead in and out for even several inches of drop. Assuming it's an interstate so reducing the speed probably isn't an option.

Hahahaha. The unofficial speed (minimum) limit here during afternoon rush hour is about 82mph across three lanes, competitive racing style. With no shoulder on the left side because MDOT made it a “flex lane”.
So yeah a dip here would have to be super long. Kind of a shame though, they just did a full road bed reconstruction when adding the flex lane, and could easily have tried to get a few more inches.

Sign says 13ft 10in. I just read where most states max is 13'6" to 14'... so that was close. As others said all they'd have to do is raise it 3 inches and lower road below 3 inches. I can't imagine water being that big of a deal, neither would the 3 inches up top.
Put a pole across the road 14ft high, say, 1/2 mile before it saying 14ft high bridge ahead.
Anything tall would hit that first.

They actually have a warning sign with yellow flashers and some sort of radar/lidar scanner a mile ahead of this bridge. If you're over-height, it's supposed to flash real time to warn you. Never seen it light up, who knows if it worked.

You're all talking like this load that crashed was complying with some standard height (14' 0"?). In all likelihood it would have hit a 14' 0" bridge too.
