DOTD has been shrinking signs for the last 5 years. Distance signs on 2-lane roads are in print so small they are hard to read at 55 mph.

Someone should make a font for highway signs that is specifically designed to be legible at long distances and high speeds...  :rolleyes:

I noticed an overhead cantilever sign on I-10 EB at LA 49/Williams in Kenner has been taken down and replaced with a smaller sign on the pole. That cantilever sign appeared to be leaning prior to its removal. If I had to guess, all of the overhead signs that were taken down were due to structural issues that could not wait for a sign replacement project. The size of the replacement signs may have been based on the pole's load capacity, which does not appear to be sufficient for a interstate standard sign.

I've noticed this year, particularly in the New Orleans area, that there are at least 3 spots where overhead pantries and pull through signs have come down (or were never finished being installed) and been replaced with the GDOT style side post mounted guide sign. The difference however, is that the LaDOTD signage is scaled down significantly compared the original signage and is hard to read until you're up close. These have replaced pull throughs at the split from the 310 northbound to the I-10, and on the I-10 eastbound approaching Loyola Dr. There are some in each direction of the Twin Span as well where the trusses were never installed into the supports to complete the gantries. I recall seeing this in Baton Rouge as well, but I don't remember where?





Anybody know what the deal is?

That would make sense. They could be operating on a queue of gantry replacement projects. They just finished replacing the gantries at I-12/I-55.

Test pilings for the upcoming shoulder project on the Causeway Bridge will start in mid-July. Actual construction is to start in the fall.

Found a nice video of the construction of the Atchafalaya Swamp Bridge by the then-Louisiana Department of Highways.

I take it Louisiana doesn't keep records of pile driving data from previous projects?

They may.  But also consider it's been several decades since those existing pilings were made and the lake bottom may well have changed some.  Undercurrents certainly would have been affected by the pilings for the existing bridge.
