Someone had to do it...
Anyway, here is my nominee:

I-10 in New Orleans. Why is it SOOO long?
I nominate the East Main St. overpass in Meriden, CT. Passes over 4 lanes of I-91 and 6 lanes + a merge lane of CT 15.

Somebody else noted years ago on this forum that Louisiana sometimes does this instead of the typical dirt approach ramps
My nominee: Eight Mile Road (M-102) over the Lodge Freeway (M-10) and Greenfield Road on the Southfield-Detroit border:

There are also two or three of these oddballs on I-75 in Michigan's Upper Peninsula:

It won't be the longest, but it's an oddball one for its length. Many have been on it but few beneath it.

The overpass in NJ carries US 322 over a few local roads, just west of the Commodore Barry Bridge. On the near side is Main Street, which continues past the southern terminus of NJ 44. On the far side is a small road (Mechanic St) that leads into a cul-de-sac with only one or two homes...and there appears to be 2 dirt roads from Main Street that will take you back there anyway.

So for about 80% of its length, the bridge probably isn't really needed.

I assumed that this was due to swamps soil in Louisiana. Why put all the weight on top of swampy ground only leads to subsidence

I think some people have already beaten you... ;-)
Emerson St passing over four carriageways of the NJ Turnpike/I-95, plus ramps.
Ridgefield Park, New Jersey just north of US 46

I think the longest overpass* on the NJ Turnpike may be over 2.6 miles in length! It's I-78; starts just west of the mainline at Exit 14, then becomes a regular bridge before touching down and becoming an overpass again before ending next to NJ 440.
(* - of course, overpass may not equal bridge in this case, but either way, it's a helluva long overpass over roads and marshland)

I think we have to discount that, as even if the road wasn't there, it would probably be more or less the same length.
Here are some criteria for what counts as an "overpass":
- over a road, or rail. If a small waterway happens to be there, it still counts
- a bridge built because of a waterway, canal, swamp, natural valley, or gorge does not count
- if the bridge is over multiple roads in succession(such as in a downtown) that is an "elevated highway/freeway/road. this does NOT discount divided highways, or highways with service roads.
- bridges for interchanges don't count, unless they are unrelated to the interchange(such as a local road going over 1 or more of the highways/ramps.
The South Wilmington Viaduct which carries I-95 in Wilmington, DE, if it counts, is pretty long.
Technically, the 6th Street Bridge in Los Angeles could be considered an overpass (and is logged into the state system as such) because it crosses US 101 (the northern end of the Santa Ana Freeway, just north of the ELA interchange). This applies to the old and now removed concrete structure (the site of many a film chase sequence -- and even a makeshift runway in the Sam Jackson-starring S.W.A.T. film remake of several years ago) and the new bridge currently under construction.
