Have you looked into OSM data? You can get a Mexico Planet file from http://download.geofabrik.de/north-america.html. It is only 88Mb. If you wanted to look at connections to cities in the US, you could pull the border states individually. I can't remember if QGIS will read PBF format files, but shapefiles are available from the same source, at no cost. The data is available under the ODbL license which should be suitable for your research.
