usala: Louisiana State Highways
« on: July 23, 2018, 09:01:30 pm »
The Louisiana State Highways set (usala) was promoted to preview last night. Any help peer-reviewing the set or answering any of the questions below (copied from README.md in the set's GitHub directory) will be appreciated.

Notes (general)

LA DOTD is in the midst (early stages) of a "right-sizing" program aimed at reducing the total state highway mileage by 25% or more. This process will eliminate or shorten many of the highways in the set. Any reports of signs being changed, or removed from former state highways, will be appreciated. More info can be found at the links below:

When available, GMSV imagery was used to ensure highways were signed. In cases where imagery was not available (or predated a highway's designation), signage was assumed. Field checking these routes would be appreciated:
  • 547
  • 826
  • 897-4
  • 897-5
  • 1018-3
  • 1018-4
  • 1018-5
  • 1266
  • 3102
Notes (individual highways)
  • LA467-1 is documented in LA DOTD's State Route Report (2018) but not shown on maps.
  • The western end of LA611-1 is unclear.
  • The northern end of LA731 is unclear.
  • The northern end of LA807 is unclear. It no longer reaches the state line.
  • Given the lack of GMSV for the area, LA897-1 thru 897-6 are drafted according to best guesses from http://wwwsp.dotd.la.gov/Inside_LaDOTD/Divisions/Multimodal/Data_Collection/Mapping/District%20Maps/District_58.pdf. LA DOTD has been contacted for further information.
  • The northern end of LA1093-1 is unclear.
  • The northern end of LA1129 is unclear.
  • The northern end of LA1255 is unclear.
  • Both ends of LA 3046 are unclear. Signage is minimal but there are no other numbers assigned to Causeway Blvd, which is considered a state highway for most of its length according to maps. The south end of the Lake Pontchartrain Causeway deserves another look as well.
  • The eastern end of LA3156 is unclear.
  • The western end of LA3258 is unclear.

A point suggestion/request: for LA 27 (Cameron), add a point for the intersection with Cox Rd. and/or Pine Pasture Rd. Both are near the Cameron/Calcasieu parish line, where the highway turns east then north. My records indicate I took LA 27 south of the parish line in order to clinch that parish, then turned back north. Either of those intersections would work for me.

I'm slowly munching through my past travels in the state, which might yield additional comments/requests. It might take me some time to assemble my list file entries for usala. But there won't be many of them, since I largely stuck to the I-/US routes for my parish-snagging travels.

I went with Pine Pasture Rd (PR440 according to GMSV) since it's closest to the parish line. The closest points are ~2 mi away, so another point here seems justifiable.

I started putting in my LA routes. So far the only thing I've noticed is a minor broken concurrency on with US167 and LA10 between LA103_W and LA749 (wayponts 31 and 32 on LA10). Looks like it's a near-miss waypoint at LA749.

If I see anything else as I'm entering routes, I'll let you know.

@mapmikey: Good idea. If you see any more parks/heritage sites that deserve a point, let me know. I added points for similar sites I noticed while drafting the set, but didn't actively search for them.

@bejacob: Thanks for catching that one. I found and corrected a few more NMPs on LA2, LA15, LA22, LA43 as well.

These will go in my next submission, which probably will happen over the weekend. I need to look at the many parallel routes on opposite river banks and play with the waypoint locations to make them overlap less.

A couple of early point suggestions.  I have a lot of Louisiana highways to go through:

LA 1 & LA 308 west of Thibodeaux: Points on each route for the crossover bridge connecting LA 1 & 308 between LA 304 (LA 1 side of the bayou) and LA 309 (LA 308 side of the bayou).
LA 157: Make a point at 15th St NW west of US 371.  15th St NW connects to AR 53.

Does that bridge have a name? I think that's the reason I left it out. If you can find anything official, let me know and I'll add it.

I did add a point on LA 1 at TigDr, which is opposite a bridge connecting to the LA 308/LA 3266 intersection.

The local newspaper called it St. John Bridge: http://www.houmatoday.com/article/DA/20060414/News/608108647/HC/ "Some north Lafourche drivers will face a months-long detour beginning Monday -- demolition of the St. John Bridge across Bayou Lafourche in Thibodaux is set to begin."
So does the parish DPW: http://www.lafourchegov.org/Home/Components/News/News/3005/334?arch=1&npage=3
And the contractor who replaced the bridge: http://www.ecmconsultants.com/road-and-bridge-projects.html

Thanks. The news article names it and identifies the church across from it, which is clearly visible in GMSV. StJohnBr waypoints will be in the next submission.
