Highways that enter New Orleans

(just for the hell of it)

Trying to figure out numbering

(from bridge dates)

History

1933: [1] [2] - doesn't look like any of the numbers match the present ones. Same in 1938, 1946, 1954. Apparently the renumbering was in 1955. 1961 has the current system. The highest number I see (on the small portion shown) is 177; there's definitely some clustering. --SPUI (T - C - RFC) 23:32, 4 May 2006 (UTC)[reply]

By district

District 4 (Bienville Bossier Caddo Claiborne Desoto Red River Webster)

U.S. Highways in 1955

11 51 61 65 71 79 80 84 90 165 167 171 190

3xxx routes assigned to freeways or other high-speed roads

Louisiana Highway 3000 is a connection to I-10
Louisiana Highway 3019 was the Pontchartrain Expressway and Westbank Expressway
Louisiana Highway 3021 was the Eastern Expressway
Louisiana Highway 3026 was the Pineville Expressway
Louisiana Highway 3040 is the Houma Tunnel and approaches
Louisiana Highway 3052 was new US 90 north of Houma
Louisiana Highway 3120 is a connection to the Sunshine Bridge
Louisiana Highway 3125 is an inland bypass for LA 44
Louisiana Highway 3127 is an inland bypass for LA 18
Louisiana Highway 3132 is the Inner Loop Expressway
Louisiana Highway 3134 is the Lafitte Larose Highway
Louisiana Highway 3139 is the Earhart Expressway

They seem to just be assigned in order of needing a number.

Grid and clustering

[3] - "all routes lower than 1241, except 191, date to the 1955 renumbering" and some more history

There's definitely a grid going on with the low numbers:

1 (diagonal) 3-5-7-9-13-15-17-19-21-23 (25 is off) - higher numbers from 27 to 35 go roughly across again but not as well
2-4-6-8-10-12-14
- 16-18-20
  - 22-24 - no clear pattern after this, but 26 to 34 fill in other main east-west routes - THERE IS NO LA 32!

Most stuff from 36 to 185 follows the clustering. The following routes don't:

Louisiana Highway 72 - way out of place in Shreveport
Louisiana Highway 141 - way out of place near Carville
Louisiana Highway 158 - somewhat out of place in Colfax
Louisiana Highway 166 is missing
Louisiana Highway 176 - way out of place in Lafayette
Louisiana Highway 179 was decommissioned in 1994 - now US 371

176, then 178 and on seem to jump around a lot. 177-180-181-184 roughly stay in the clustering, though all but 177 are in already-covered areas, and 176-178-182-183-185 are all over the place. Thus the original clustering may have ended at 177, with 176 skipped (or later reassigned?). --SPUI (T - C - RFC) 13:14, 8 May 2006 (UTC)[reply]

Louisiana svg shields

I have created a few shields, any feedback is appreciated. --Holderca1 02:20, 13 November 2006 (UTC)[reply]

New Louisiana Highway Shields

As mentioned at Wikipedia_talk:WikiProject_U.S._Roads/Shields, Louisiana's highway shields are changing as of this year - they are now being replaced (as needed) with black and white shields with a very similar design (no "outer ring"... see [4]) rather than green and white shields, due to the high costs of using green ink. As suggested on the WikiProject page, we should begin the slow and tedious process of converting the current shield images to the new color scheme. --Mr. Brown (talk) 19:04, 19 June 2008 (UTC)[reply]

When I used to drive east from Texas, much of which lacks vegetation, I was inexorably so favorably impressed by the greenery of Louisiana, so incredibly well represented in those beautiful green highway shields. Texas was all black and white, like an old television, even down to the creativity-challenged box shape of the shield for Texas state highways.

Now, alas, it seems that LA DOTD is trying to pull the wool over our eyes slowly and stealthily, as if knowing that people will not regard these new black-and-white signs as an improvement, replacing as they do the luscious and established iconic green ones. I don't buy the argument that green paint costs more. Many things this state does cost more and have no benefit. It's more likely that the LSU engineers who thought this up were out to get Tulane green off the signs. But these new signs are just ugly and—for folks like me who enjoy seeing something green after being in the arid West—disappointing.

Lush, green Louisiana is now becoming black and white. This new sign is ugly. May it go the way of New Coke. It ain't over till it's over. Think about it. Rammer (talk) 04:01, 20 November 2008 (UTC)[reply]

Pre-1955 Route Numbers

As we all probably know, before 1955, Louisiana's highways looked very, very different. If anyone wants to add to the list, just slap on a number, where you found the route number, and date of bridge, if possible. Mcdonaat (talk) 19:22, 17 December 2011 (UTC)[reply]

State Route 91 (LA 19 between Mississippi Line and Norwood, only bridge available) - 1952 State Route 200 (LA 34 in West Monroe, between US 80 and Thomas Rd.) - 1942

1991, 2008 shields

What's the difference between the 1991 and 2008 shields. I see no significant difference, if not, difference at all. Kevon kevono (talk) 20:00, 8 May 2016 (UTC) (What the hell is UTC?) 13:00 (PT)[reply]

What are you talking about? Please give examples. –Fredddie ™ 20:48, 8 May 2016 (UTC)[reply]

I figured it out, but in the future, please give some more context in your questions. –Fredddie ™ 20:50, 8 May 2016 (UTC)[reply]

Now I'm asking, what's the difference between the 1955 and 1991 shields on the inbox? Kevon kevono (talk) 23:11, 10 May 2016 (UTC) (What the hell is UTC?) 16:11 (PDT)[reply]

The newer version shows more detail and accuracy in the state outline.Britinvasion64 (talk) 23:44, 10 May 2016 (UTC)[reply]

I see it, thx. Kevon kevono (talk) 02:02, 11 May 2016 (UTC) (What the hell is UTC?) 19:02 (PT)[reply]

Should this be split?

This list appears to be a little too large and I think it's better to split it into multiple subpages. Dylpickle2k (talk) 23:54, 26 September 2022 (UTC)[reply]
