Roads that I'm looking at using on my end to end bike ride

 here is the roads that I'm looking at taking north to south on my end to end bike ride -I'm not to sure where I'm staying each night on the ride  as it will depend on how far I ride each day - some where around 50 to 140 km a day and how many rest days I will take ( about one a week or so - maybe more ? )
