Kidding aside, and my bad drawing, but the gist is we've all been on roads where there's a ramp up, over, ramp down. I'm no engineer but it doesn't seem all that expensive to do and easy way to get 3-4ft more clearance.

What in the world prevented the DOT from lowering the roadway underneath to prevent this?
Yeah that too. But this crossing has been clearly labelled as deficient, unusually low, for a long time.What in the world prevented the guy who loaded the machine from tucking the bucket in and lowering the boom like he should have
Well we got a fresh one near Ann Arbor on Friday evening.

And now what we get
Estimate is 8 MILLION dollars to replace the bridge. It's not a vital link around town, but the detour is several annoying miles either way if you need to cross the highway here. It was a "low" bridge at 13 feet 10 inches, with multiple warning signs preceding it.
Haha yeah I mean the picture doesn't show it, but the overpassing road does already have long gentle ramps/berms up to that existing bridge level. The surrounding land is basically at the same grade as the highway itself.Kidding aside, and my bad drawing, but the gist is we've all been on roads where there's a ramp up, over, ramp down.

It wouldn't cost that much 1/2 mile either side "ramp ahead 45 mph". Something like that.

I think the legal maximum vehicle height was 13'6" back when the original Interstates were built. I-90 through eastern Washington had a bunch of overpasses that were an even 14' that have since been replaced or altered to get them to 14'6".This bridge is from the late 60s or early 70s - I guess design standards were a bit more marginal back then.
The problem is an arch like that requires that the arch go all the way down to the ground or have a tie across the bottom of it to keep the legs from spreading apart, as such you wouldn't gain any height from that. If they were to do anything they would replace the vertical supports with taller ones and move the bridge deck up.Kidding aside, and my bad drawing, but the gist is we've all been on roads where there's a ramp up, over, ramp down.
