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:


* http://wwwsp.dotd.la.gov/Inside_LaDOTD/Divisions/Multimodal/Road_Transfer/Documents/Right-Sizing%20the%20State%20Highway%20System.pdf
* http://wwwsp.dotd.la.gov/Inside_LaDOTD/Divisions/Multimodal/Road_Transfer/Pages/default.aspx (maps indicating route status available via links at upper left)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
* 3102Notes (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.Sources:

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.

A point suggestion:  Poverty Point World Heritage Site on LA 577...

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.
