As tolls go up, more and more motorists simply decide to take slower alternative routes and save themselves the money.

I am in NE Ohio, just north of US30. I frequently drive from here to Iowa or Nebraska. I take US30 from here all the way across Ohio and Indiana. Then I go north to catch I80 the rest of the way. Saves a lot on tolls, adds less than an hour to a 10 or 12 hour trip. US30 is mostly 4 lane, limited access divided highway in Ohio, and in much of Indiana 4 lane divided, but not limited access.

Yep, just as ECON 101 says - if you want less of something (such as people using a limited-access highway), simply raise the price.
