I use the toll road between Oklahoma City and Tulsa. It is the only straight shot to Tulsa and the road is nice.
I also pay the toll on Hwy 301 bridge to get out of Maryland. Cost is $12 and is much better than the long drive around Maryland if you are starting from Southern Maryland.
Basically I have used some toll roads and avoided others. It just all depends on if we are trying to save time or money. Some cannot be avoided without wasting a lot of fuel and time.
