While updating my .list file today, I happened to look a bit more at US 11's path across VA, and found something interesting on one of the I-81 overlaps. Between 167 and 168 on I-81, US 11 is concurrent with it northbound but not southbound. Perhaps the concurrency should be broken in TM, as someone who only took I-81 SB through here technically wouldn't have been on US 11?
