Diagonal routes that could be on here, but could be signed either way, are US 52, US 62, and I-71.

US 52 is signed either way, changing from N-S to E-W at the Ohio River.  I think it changes again further west/north. 

[TEG24601]

I-69 from Lansing to Port Huron.


US 101, goes from N-S to E-W, then to S-N.

I-69 from Lansing to Port Huron.

Is that section on I-69 labeled north-south or east-west?

East-west.

Twice, actually. It's N-S in Iowa and Minnesota, and E-W again in North Dakota.
