Why is this road marked Interstate 805 and not Interstate 508?

Nothing is mentioned about this idea in the text.

As I-5 is a north and south road and not east and west road. It seems more logical to make the present I-805, which is a north and south detour or alternate to I-5 to have a number that reflected the relationship between the I-805 and I-5 rather than to the I-8. That would make the present I-805 into I-508 or I-50X. I-8 has no other related 3 digit branches anywhere along it's length so there would be no conflict if there were spurs, bypasses, connectors, etc. on the existing I-8. Has anyone ever came up with an explanation for this anomaly? Michou 13 (talk) 17:19, 25 July 2018 (UTC)[reply]

Nothing is mentioned about it in the text because we'd need a source for the idea that some other number was considered.

Since I-805 begins and ends at I-5, so it functions as a bypass for I-5, it was numbered as an auxiliary of I-5. There's nothing anomalous about this situation at all. Imzadi 1979 → 20:01, 25 July 2018 (UTC)[reply]
