We're taking a long road trip from Saskatchewan to the Dallas-Fort Worth area later this year. On prior long road trips I've gotten toll transponders (in Illinois and Florida), paid cash, or done drive-by-plate billing (Toronto, ON and the Seattle, WA area, although it turns out neither jurisdiction bills Saskatchewan drivers :) ).
Our route takes us through North Dakota, eastern South Dakota, and Iowa along the Nebraska border to the Kansas City area, then southwest through Wichita and Oklahoma City to Dallas-Fort Worth, then northwest to Santa Fe, north to Denver, then to the Black Hills of South Dakota before we go home.
I believe the only tolled roads we'll face are in Kansas, Oklahoma and Texas. I've ordered a TxTag, which has no maintenance fees and will take care of us, it seems, in both Kansas and Texas. Is this correct?
And what about Oklahoma? Can I pay cash tolls? Is exact change required? (Or can one pay by card?) It seems that a single transponder for this entire area isn't too practical.
Am I missing any areas?
For the record, the Illinois and Florida passes have no maintenance fees and mail to any US address (and I have one). They saved us a lot of time driving in those states. I'd like to have as much of that benefit on this trip as I can - fewer things to think about.
