I commute to the DC area twice a week. Richmond to Fredericksburg doesn’t have much traffic, but it will take 45 to 60 minutes depending where in Richmond you are. Another great commute option is the train. I take the train every other week and pay $20 round trip to Alexandria. Not sure how much it is to Fredericksburg, but it’s really nice and stress free. The morning trains originate in Richmond, so rarely run more than a couple minutes late. You do have to buy in advance to get the best deals.
