Tuesday morning it took 6:15 to get to Richmond taking I-95. Thought by leaving at 5 am I'd miss most of the worst traffic but still hit congestion north of Baltimore. On the way back I left Richmond after 6 pm and it took 5:20 hours. And that did not include pick up / drop off of rental car.

Will be flying in the future. It takes less time and is less stressful.
