Tollways are designed to generate revenue in perpetuity. The tollway in northern Indiana that was built long before I was born is still raking in the dough!
Revenue from the tolls on I-80 are currently committed to the I-69 project.
The ONLY place I have ever heard of a toll booth being taken out permanently is the Coronado Bay Bridge. When the bridge was built, it was tolls both ways, then when I was stationed out there, only going from San Diego to Coronado... the last few times I’ve been there (1999 through 2015), there was no toll at all.
I can’t believe it, but yes, in California, they REMOVED a tax (toll).
