Do you mean burlingtong Vt not VA if its burlington vt depending on weather 1 to 2 hours. Bc you go south 89 interstate and get off exit 8 in montpelier and have to go route 2 to st johnsbury which is a local route with different speed limits to St J.
It takes about 1.5 hours
It's about 72 miles or 90 minutes without traffic.
If your flying, look on your maps, and if not, just look on Google maps
