Bumps in roads that cause problems for motorists that take forever to fix

I remember living in New Jersey many decades ago and distinctly remember NJDOT ignoring a linear bump on US 1 & 9 at Grand Street in Elizabeth.  They actually had a bump sign on NB US 1 & 9 north of the Jersey Street intersection which probably is a quarter mile away.  One day seeing that sign, I took it easy of course only to find no bump like the sign says, then as I accelerated after riding a considerable distance and not experiencing anything to only hit a hard bump as the asphalt ended and the original 1940 concrete began just after Grand Street.

Anyway, that bump lasted for well over a year before NJDOT did something about it.

Also on US 22 approaching the viaduct in Newark after leaving Weequacke Park there was a large bump there for where the asphalt on the approach settled about a foot or two below the bridge deck and for a long time you would not hit it hard, but your vehicle would actually go airborne. 

Yes these were circa 1987 and 1989, but I was wondering the many places still that you all have experienced something similar and the DOT's will not do anything to fix them.

On I-17 SB near exit 293, there is quite an abrupt rise in the pavement. It can be hard to see sometimes as it doesn't really stand out, but if you don't see it, you'll sure feel it as you go over at 75 mph. Not really dangerous, unless you aren't paying attention/ don't have a good grip on the wheel, then I suppose it has the potential to cause one to lose control.
I think it's actually quite fun, though, and I look forward to it whenever I'm on I-17. You should see the semi trucks as they bounce over it!

Come up here in March and try to find a road that doesn't have a bump that causes problems for motorists and takes forever to fix.

In Michigan:  US-23 southbound between Brighton and Ann Arbor, frost heaves every hundred feet, alternating between a mild bump and a sharp one.

M-153 (Ford Rd) under I-275 has a rather large frost heave under the overpass.  It's been there for years.

Come to think of it, frost heaves are a huge problem all over Michigan.

Each winter certain roads around here start getting bumpa thanka to the warming and freezing. Sections of 95th street by me are having manhole covers start to sink or in some cases rise. Couple have been fixed, but come March there will be plenty more bumps

Arizona 51 northbound has an abrupt dip in the far-right lane right around the Camelback Road overcrossing. It's been there for years, gradually getting worse and ADOT recently put a BUMP sign warning of it.
