I always take Springfield but for some reason my GPS would say to go to the other way. Then I noticed there was a light so I was wondering if it was just trying to make it easier. I'm coming from the burger shack area of Chantilly.

Which road are you coming off of and which direction are you traveling on this road? Why wouldn't you just go towards Springfield?

When you get off to the parkway at Chantilly you can go towards Herndon or Springfield. There's a light at the Herndon exit, can you make a right there and get on the way towards Springfield or is it both lanes making a left and it would take you the wrong way?
