These roads run parallel to each other and you can take the left airport exit when you are a few miles from IAD. Why? Because you are more likely to get pulled over if you are speeding on the non-toll road rather than the toll road. It will cost $2 or $3.
Sorry, I disagree with this. I drive round-trip on the Access Road (non-toll road) 3-4 times a week - and there is significantly more police enforcement activity on the TOLL ROAD than on the Access Road. Bottom line: don't push the speed limit too much on either road.
