Why have the toll roads in Colorado (Northwest Parkway and E470) closed their toll booths and gone to non-stop tolling?
Non-stop tolling is safer and more environmentally friendly. With non-stop tolling you don’t need to slow down to exit the road in order to pay at the toll booth, and then accelerate again to merge back into traffic. This not only helps avoid accidents, but also helps your fuel economy by maintaining a consistent speed.
