Stay to the right.

Thank you so much!!

If I'm not mistaken it would be the 3rd lane from the left as you approach the 66 on ramps. Then a new lane opens on the left making it four lanes and that new lane takes you to 66 Express Lanes. 2nd from left takes you to 66 normal lanes. 3rd from left takes you to 66 or you can stay stay straight on 50 and 4th from left keeps you on 50.

Yes eastbound on 50 towards Fairfax City, coming from the Centerville area. Thank you!

Need more information. Are you saying that you're travelling eastbound on 50 towards Fairfax City? There is plenty of signage to let you know which lanes to be in whether you're going onto 66 (eastbound, westbound, HOT lanes, etc) or ... staying on 50 eastbound. In general stay, in the far right lane when there are just the 3 lanes before you start to pass Fair Oaks Mall and keep going straight.

When driving to Fairfax from 50, what is the trick and not getting caught up in the 66 lanes? Google is not a help because it said to bear right but this took me to the lane that takes you directly to Fair oaks Mall. There's only one particular lane for a while that doesn't put you on 66, which lane should I stay on to stay on the route to Fairfax? Thank you
