Upgrading CA 99
geoking111:
What number should CA 99 get if it is upgraded to interstate standards?
V'Ger:
Stay the same!
mapman:
If it had to change, I think I-7 would be best, from a logistics perspective. California doesn't allow duplication between interstate and non-interstate highways, so either CA 7 or CA 9 would have to be renumbered. CA 7 would be the easiest number to replace, since it's simply a short connection between I-8 and Mexico. CA 9 is a major two-lane highway through the Santa Cruz Mountains and San Lorenzo Valley, and would gain a lot of opposition if changed to another number. A change from CA 9 would also disrupt many properties, many of which use the highway in their addresses (such as 5010 Highway 9).

It would never happen, it's too near and similar to I-5. Besides, an Interstate has to span at least 2 states. (Except the ones in Hawaii)

I'd go with I-7, just because it would be the most logical interstate number.

Do I-4 in Florida, I-12 in Lousiana, I-16 in Georgia, I-43 in Wisconsin and I-97 in Maryland know that ;-) ?
