Completed using ArcGIS Pro Network Analysis toolset. Essentially will follow the shortest distance. Which in almost all cases will also be the quickest.
Into the D.C. beltway: (and yes they follow several other roadways the farther out you go)
Red generally follows I-80/I-70 to I-270
Green generally follows I-81 to I-66
Blue follows I-95 south of D.C.
Orange follows I-95 north of D.C.
Edit: all colors were tested for color blindness and should be slightly different shades. May have fucked that up in Adobe after exporting from Arc :/
And yes, there are a few errors in how colors were overlayed. You miss a few when you are copying hundreds of roads into one layer.
Edit2: if you want to be nitpicky about my use of "quickest" over "shortest" go ahead. But I'm happy with it :) it will not be perfect everywhere
Edit3: yes bridges were taken into account just not shown because of issues with the water/basemap
I like how with the exception of the very southern tip of California, the routing to the majority of the US to the west is basically Interstates 40, 70, 80, and 90.

DC 495 beltway as a black circle is perfectly represented
