This page will link to the project to recover the original routes from the many ISDT. Hopefully at some point we will get most of them mapped using Google Earth and Google Mapengine which will enable us to provide recent aerial images overlaid with the routes, route profiles, hopefully enlightening communities of their past place in the event.
I would like to assist in the mapping process; I am riding many of the old ISDT routes in my spare time.
I would love to hear more about this and which areas you are riding and would be happy to feature any information you have to share on the routes as they are today – thanks
