I just drove the DTR out to Reston for dinner. On the way there I took the airport lanes to skip traffic, and did so legally by filling up at the Exxon. On the way back I took the regular lanes. Paid my dollar toll entering at Reston Parkway, then upon approaching the main toll plaza, figured instead of paying $2.50, I'd exit at Spring Hill, pay $1, go straight across at the signal and re-enter, paying another dollar. I was half expecting them to have made the straight through move illegal, but they didn't...and they can't, since buses have to go that way to get to Tysons Westpark transit center. Might only be 50 cents, but it only involves about a minute of time, and if rather pay as little as I can for Metro via tolls if I'm not in a rush. Could have saved even more if I took Jones Branch to the Express Lane entrance; where the toll for
jones branch to 495 north is generally 40 or 50 cents, and you get "expedited" service rather than sitting on the DTR to 495 north ramp which is often clogged.
