Fairfax is about exit 160 on I95, so there's 160 miles knocked out before you hit the NC state line. I95, IIRC, is 181 miles through North Carolina, so you'd have 140 miles to go before you hit the 300 mile mark, which would put you at MM 41. That would be NC95/Chickenfoot Road/South Main Street in Fayetteville, North Carolina. Trying to remember what's off that exit from my time being stationed at Bragg, but I'm drawing a blank here, unfortunately.
