Why can La DOTD/road contractors not build a proper bridge approach?

This may be more of a thing in the New Orleans area with all of the canal crossings, but every bridge ramp launches your vehicle when it gets to the concrete bridge section.
How hard is it to match the bridge slope and create a smooth transfer onto the span?

Ground sinking/settling probably causes it.
And they probably don't want to proactively re-asphalt it because you're just adding more weight

It's because yalls soil sucks arse. We were putting piles in at 80ft for Shintech Plaquemine and still barely getting 5 blows/foot. Stuff is like mud soup for a very long way down. Surprised theres not more structural failure in the state honestly.
Eta: for clarity, the soil sucks arse to build anything with height. For growing crops its A1

Just buy a Dukes of Hazard horn.

But if it was just soil issues, wouldn’t the whole approach sink leaving a several inch concrete exposure at the transition?

Tradition, mostly

Bridge supported by piles and the road approaching it is not. Road sinks faster than bridge due to crappy soil. It's why you always see patches where the approach meets the bridge.

Tradition? Because a past governor owned 50% of a string of front-end alignment shops. The governor was instrumental in handing out road and bridge contracts. You build per request, or you don't build again.

Just be thankful you have a road that would otherwise be underwater if it wasn't for engineers.

Isn't most of the interstate elevated? Is it state or local? Either way it's soil or elevation, i bet.
