I am a little confused by the wording. You say bypass around Tepic and east of Tepic and speak of Guadalajara and Puerto Vallarta? I recently started a thread about the new Guadalajara bypass but am not sure if that is what you mean . . . https://forums.trailerlife.com/index.cfm/fuseaction/thread/tid/28737896.cfm . . . Depends on where you come from and where you want to go. You could take this road to hook up with 54D down to Manzanillo and then up to Melaque etc. Would this be what you are asking about? The road is making progress but no one seems to know official opening date. There are lots of new roads being built or upgraded all over Mexico and I was recently on an SCT website or other MX gov't site where I did see some new roads mapped. How to get to that website now I forget. We have been on 200 north and south of Puerto Vallarta but never been to Puerto Vallarta so don't know that area - down to Lo de Marcos - and up to Perula from Manzanillo. There is also a sort of bypass from Tala I think to Campostela someone told us about but that probably isn't what you mean. Maybe you can clarify what you mean with your question - what route do you want to take and where are you coming from and where are you going etc.?
