I pay tolls on some roads in Texas, Oklahoma and Kansas.
Those are toll road fees. I do not pay tolls in other states. Some I consider too high. Some like Florida, it seems every time they do any repairs, they make the highway into a toll road. And some of the newer ones can charge 5 or more dollars per mile for an RV with multiple axles.
I do not like driving the Florida Turnpike from Wildwood to Miami. Mainly because there is no way to get off for many stretches. If there is an accident, or a need to stop your RV - you are stuck inches from the high speed lanes. Or has happens to my Son-in-Law and his family - 8 to 12 hours long sitting in a backup.
We did two winters in Florida, centered around the Fort Lauderdale area and never drove on a toll road. It can be done.
$100 for a toll road - you can be surprised quickly and charged that much.
Almost no toll roads still have toll booths. You drive past and one of two things occurs. If you have a universal toll pass module, of a highway specific one like EZ-Pass, Sun Pass, NTTA Toll Tag, Pike Pass - that is billed.
If you do not have such a pass that tollway recognizes - your license plate is recorded, and a bill comes in the mail for the toll fee. Which is always higher than the pass rate, maybe 25% or more higher.
----------
Another big factor in pricing is the number of axles. That is how most toll roads determine the fees.
The OP is driving a two axle motorhome. Most places he gets billed at the same rate as a passenger car most places.
Three axles - a pickup pulling a single axle trailer - is a higher rate usually 150% to 200% the regular rate.
Four axles - a pickup and a 5th wheel, a motorhome with a toad - which is likely what the OP has - that is usually 200% to 400% of the base two axle rate.
Five axles - a motorhome with a tag axle and a toad - is 400% - 800% of the base rate. Anything with five axles is billed at the same rate as a 65,000 18 wheeler commercial truck. (and a tag-axle motorhome can often be over 50,000 lbs).
So, on. The Florida Turnpike 2023 toll sheet (
https://floridasturnpike.com/wp-cont...rida-07-24.pdf) List the rate for two axles from I-75 south to the Three Lakes Plaza south of the Orlando Metro Area (73 miles) is $4.13 for two axles with at the Sunpass rate, $5.18 for billed to the plate
Three Axles - $6.21/ $7.77
Four Axles - $8.28/ $10.36
Five Axles - $10.35/ $12.95
This isn't too bad, because it was built when the state built and funded toll roads.
==========
A current 'fashion' is to create 'express lanes' down the center of a stretch of a highway, often in busy traffic cities. Most of these are run by FOR PROFIT companies under franchise type agreements and though not signed as toll roads, are very expensive.
One that comes to mind is from downtown Fort Worth, TX north next to I-35W to near Alliance Airport. A distance of 16 miles. On demand pricing for the TX-Tag highway was $14.05 about a year ago and took right at 13 and 1/2 minutes (80 mph speed limit) That was for a two axle vehicle (jeep Cherokee) at near noon. At five pm the rate would be $42.15.
For a four axles vehicle - $82.45, for a five axle vehicle $124.60.
If the person did not have an automated tag billing - that would be $166.75. And unless the GPS or other navigation was not set to Avoid Toll Roads - the driver would never know he was on a toll road, not the 'Express Lane' as it is billed. There are signs above the tollway a mile or two before the entrance with the current rate. Easy to miss in a new city.
My son-in-law says the on-demand toll lanes in I-95 in Broward and Miami-Dade Counties work the same way.
Those segment has 'demand based pricing' if you hit that area in what they call a high demand time - the price goes up by two, three or five times the normal rate.
