Awww, poor I-39 can't gain a mile or two by going to the WI-29 westbound interchange.

These are very helpful, I also have copies of all AASHTO/AASHO route numbering meeting minutes going back to the 1920's.
In addition, I have copies from all 50 states + 1 territory of all Interstate System route numbering changes approved by the BPR/FHWA from 1957 to present.
All the above information has been compiled into a spreadsheet format and ACAD maps have also been created referencing every change that has been made. I am into the final stages of finishing it, I just have a few loose ends to tie up.

I have been in contact with the FHWA regarding this book for a while, they have been very helpful.
In the End, It will be over 300 pages long.

Take Care,
Stephen

As a "Future" route or as a full-fledged Interstate?

I have been at this project since 2000, I had to make a choice between a website or research for the book. SO, I chose research for the greater good in the end.
