Intrastate U.S. Highways

Agreed, that would leave out the routes in the Northeast where most are less than that and through two or more states.  Many are important enough as there is quite the population and the need for off interstate thoroughfares.

Problem solved and let's 301 terminate at its parent

Not sure that's necessary considering that 301 already has two concurrencies (FL/GA and VA) with its parent.

How about interstate US routes less than 300 miles in length be decommisioned? I'm looking at you, US 730.

AASHTO guidelines do not prohibit US highways that are under 300 miles in length as long as they cross a state line. Haven't we been through this before?

Short interstate US highways serve a purpose, it provides a uniform numbering system for roads that cross state lines. That system would basically get rid of the US highway system in NH/VT/ME. It's a usual navigation tool.
