Here are a couple ideas that may or may not work depending on the driver = if you come down the new road which may be a continuation of 80D - from 15D - east of Guadalajara - you come out on MEX23 north of Chapala near MEX35 - now you can cut across country on a good 4 lane local road with a few traffic lights and some topes - you get to MEX15 (not 15D) south of Guadalajara before it runs into 54D - this goes north of Lake Cajititlan - it is JAL113 - not a super highway but good enough for our purposes - after you hit MEX15 and cross it you end up on JAL601 which goes up by Tala and then eventually reconnects with 15D west of Guadalajara - this may not be the most desirable route for some due to length and topes etc - but it is all good road and keeps you far from Guadalajara traffic and that periferico - the maps will give some idea but you should check your own maps etc - or get on OSM and zoom in to clarify details..........
