I'm trying to write an article about US 80 in Louisiana on Wikipedia (which is currently in my user sandbox) and I can't make any sense out of the GIS source used by most articles to measure the highway's distance or mile markers. Can somebody please help with that? I want to put down the total mileage and mile markers for major intersections for US 80.
What's the GIS source?
Here are a few I know of off the top of my head:
MP 82.2: US 80 @ LA 507, Simsboro.
MP 83: US 80 @ LA 150/LA 563, Simsboro.
MP 87: US 80 @ LA 149/LA 3005, Grambling.
MP 89.4 & 89.5: US 80 @ LA 818, Ruston.
MP 91.1: US 80 @ LA 544 (formerly LA 3012), Ruston.
MP 92: US 80 @ US 167 LA 146 NORTH, Ruston.
MP 100: US 80 @ LA 145, Choudrant.
MP 104.5: US 80 @ LA 151, Calhoun.
MP 111: US 80 @ I-20, Calhoun.
MP 116 (approx): US 80 @ LA 15/LA 546, Cheniere.

This is the source most Wikipedia pages use for the mileposts and total length reference. Im having trouble figuring it out. Honestly, I wish Louisiana had a state highway log.

A couple of years ago when I was making KML files and maps for Louisiana highway articles there (most of which are now redirects and the KML files don't work anymore anyway :( ), IIRC the GIS file was really only good for determining if a route existed and getting a total length of a route. If I was updating the route junction list and needed the mileposts, I just got them from Google Maps. I started by getting directions from the starting terminus and then just dragging the end point to each route/interchange.

Thanks for the tidbit. This information helps a lot. I currently put the Louisiana article on hold to work on an Alabama one.
