Take a yellow subway line toward Huntington station and get off at Pentagon station. From there take a bus 21A, 7A, 7F as closer as u can to the King street, and then walk along toward 395 highway, you will pass a gas station and you can start to hitchhike before you will see a sign saying Richmond. That's where you need to go. It's enough place for a car to stop and the traffic is not too crowded.
Direction Annapolis or the Delmarva Peninsula
Just catch the orange line to new carollton as it will get you right next to a fairly busy ramp onto the interstate 50. You can also catch one of the buses that leaves from there and goes to Bowie, but there is much less traffic
This is good for getting on to Interstate 81, a popular truck route
Take the orange line all the way out to Vienna, the last stop westbound. From here, catch the 642 or 632 Fairfax Connector bus to Centreville. Check with the bus driver to make sure that the bus goes all the way. Sometimes the driver will let you off right near the highway, other times walk from town ~1km. The on-ramp from Sully Rd onto I-66 is the connector for Dulles Airport, so it is popular with folks going a fair distance. There are a pair of truck stops once you hit Interstate 81, just south of the town of Strasburg
Check out the hostel on K & 11th streets. The lobby has phones and internet (for a price) and free billiards. Wait until somebody swipes their keycard and then follow them in. On the second floor is a kitchen and TV room. Guests mark their food in the fridge with the date they're checking out, so feel free to help yourself to any food people have left behind. You can nap in the TV room.
