Talk:Mexican Federal Highway 180D

Why were these built?
The article doesn't say why these highways were built. Was it to relieve congestion on the main road? cc Ed [talk] [majestic titan] 03:17, 18 February 2017 (UTC)
 * Any highway with a D on it in Mexico is a toll road. Toll roads are usually one of several things: "short routes" between major cities, cutting travel times compared to the "free" highways" (such as Champotón-Campeche); bypasses, like the incomplete one for Cardel; and major projects like tunnels and bridges that are tolled to maximize the value of their time savings. There are also some really big toll roads, like the ones that terminate in Mexico City. From the capital toll roads (sometimes in part, sometimes in whole) go to a variety of major cities, and a couple go to the US-Mexico border. Raymie (t • c) 05:17, 18 February 2017 (UTC)
 * Can you add some of that very helpful context to the article? :-) Ed [talk] [majestic titan] 06:54, 18 February 2017 (UTC)
 * It'd be difficult to add here, but I've added it to List of Mexican autopistas. The lists have become outdated. One major obstacle is that numbers are secondary to the city-to-city names, and Google Maps is actually inaccurate. Sometimes even the road signs are different from the SCT Datos Viales lists (e.g. Highway 187D is signed 145D)! Raymie (t • c) 07:39, 18 February 2017 (UTC)
