US 90 vs I-10 across from Louisiana to Florida

Either one has sections that are rough due to slab shifting. US90 in the Lafayette/New Iberia section is very congested with both construction and industry. East of that is near interstate quality until New Orleans. If time is a concern Use I-10 to Baton Rouge then I-12 until it reconnects to I-10 near Slidell. Avid rush hours at Baton Rouge and if east bound stay in the middle lane on the Mississippi River bridge to get thru the one lane choke point on the east side.

Its been several years ago, but I drove west to east on I-10. Most of it is bridges over swamp land and there were holes in it that a horse could fall through. No experience on US 90. BTW, unless you intend to visit New Orleans, the shorter route turns into I-12 just east of Baton Rouge and re-connects with I-10 near Slidell, LA. The "detour" to New Orleans adds about 25 miles to the trip.

I think we may take US 90 across Louisiana and then drop down to I-10. We've been traveling for three months and are getting anxious to get home.

A couple of nights ago we were chatting with a couple from Mississippi. Worst roads subject came up and we both agreed: I 10 in Louisiana is the worst road we have been on ever. And we have driven the Dalton highway, which is bad but for completely different reasons. Louisiana has no excuse for the condition of that road.

Yeah a lot sooner, 90 meanders thru a lot of small towns, nice if you aren't in any hurry. I think 98 to the south is much better on the scenery, it wanders along the gulf coast. But it is longer than 90.

US-90 is the scenic route and I-10 is the push me along and I will get there sooner route.
