You can do US 1-US 2-US 3-US 4-US 5-US 6-US 7, albeit in 5 states (ME, NH, VT, MA, CT).
That requires making a U-turn (only direct connection between US5 and US6 is 5N→6W).
We've done to death all the freeway interchange gaps, but how often do two US highways cross without an interchange?
6 and 34 in sunny Lincoln, Nebraska.
There's really no direct connection between US 20 and US 52/61/151 in Dubuque, Iowa. You have to use various surface streets to make the connection.
US 20 crosses US 219 in Orchard Park, but there's no direct connection. You have to use either NY 179 or US 20A to make the connection.
The best example I can think of is US 31/280 @ US 11 in Birmingham. Only one movement (US 31 North to US 11) is direct, the rest involve surface streets.

US 45 and US 11/80 outside Meridian, MS. No connection, period...US 45 is a freeway and US 11/80 is too close to I-20/59 for an interchange here.
I 140/US 17 and US 117 in Wilmington NC, where a daughter route crosses its parent without an interchange.
Going by official state routings, US 206 crosses over US 1 in Trenton, NJ, but there are several signed routes to connect the two (and also Business 1 too).
