To be fair I like the sentiment but the message is just wrong at least in the United States. Here toll roads are privately built roads in conjunction with public entities. They contract generally defines a certain period where tolls can be collected to recoup the cost of the road with profit so say a road costs 5 mil they might be able to collect for 10 years with a estimated value of 40mil.
It's crazy and nonsensical when the smart money is in public funding of grand national projects like high speed rail with a focus on cargo and intercity travel preferably underground. Japan is doing a huge project that moved most of their services into deep underground tunnels and I think that's a smart thing to do for the us.
