I have removed I-290 since it is not in Ohio. Reaper Eternal (talk) 20:10, 19 January 2011 (UTC)
I-290 was a former designation for part of what is now I-490; see Interstate 490 (Ohio)#History. It should be listed here in some form (such as a different colored row that denotes that the designation no longer exists) since our (WP:USRD) coverage of highways doesn't stop at active routes. – TMF 21:21, 19 January 2011 (UTC)
