Why does this bridge look scary?

Is it me or does this overpass look too low to me?
In Texas that would have a clearance sign. Then again, there would also be one where the ramp goes over 70 Bypass.
South Carolina has them too.

Sherman Minton Bridge sucks. I don't like elevated bridges. I'm sure it lights up but it's VERY boring to drive on when you are on the lower level. And it looks scary cause I feel like the top deck will collapse!  :-o
I've crossed that bridge at least 16 times by now. Is 800 meters of boredom on the lower deck of a bridge too much for you to handle?

Fortunately, there is an alternative. You can cross over the Ohio River on the I-265 bridge in the area for a low price of $2.10, only $2.10 more than the $0.00 on the I-64 bridge !

Yes, I would go with I-65!

Is this to the Sherman Minton Bridge or I-65?

I think the point is some people don't like the fact that the bridge design doesn't use center supports. The single span is longer than the length of the individual spans if it had used a center support. The spans are up to 100' feet but that is far less than the length of plenty of other spans in deck bridges.

Actually it is a safer design, because the biggest reason deck bridges fail in the US is because traffic (most often TT-Combos) strike the center support (that you so badly miss) and knock one or both sides of the bridge down. 
Let's build what we need as economically as possible.

The wide shoulder caught my attention. This overpass was built to accommodate future road expansion. That's a good thing.

No bridge is as scary as the original Galloping Gertie.



Spoiler: It didn't make it to its first birthday.

Due to having no support columns in the median.

Modern bridges (not all) are designed like that.

Now if it was concrete beams, then it would be MORE scary!

I guess it depends on the length too

Though without piers, the bridge is not without peers in NC (ran across this one yesterday)...

A better question is, why does it look like NCDOT wants to reuse the old road as southbound lanes, when it looks like the existing bridge is just barely capable of handling two more lanes.

As for scary bridges, I thought that link was going to lead to something like the Delaware Memorial Bridge or Chesapeake Bay Bridge (US 50-301), or something like that.

Confused by this question...putting the old road back into service as the SB lanes would require a new bridge and interchange entirely unless there were going to be tight S curves on both sides of NC 87 bypass.
