I cannot believe that this section of highway has been neglected for so long, especially in an area with so much money and so much desperate need for expanding the commuter corridor of San Francisco.
It seems to me that California should be making greater use of toll roads for critical projects which can't get funded. If it is going to take 20 to 30 years for certain projects to be built, you could potentially get the road built and paid for in that same time period, ultimately making it a free road in the same amount of time. For example, the Route 152 project near San Jose would be a good candidate.
I don't like toll roads, which is especially painful because I'm in Texas which is being transformed into the toll road capital of America. I wouldn't wish that future on any other state.
But toll roads can be part of a solution plan for chronic congestion. In addition, it is easier to get toll roads built because
1. They don't use traditional public funds, which make it more difficult for political opposition to block the project
2. Opposition is less intense because the opposition likes the fact that motorists using the highway are paying for the privilege
3. Surplus revenue can be used and abused by politicians, which gives politicians more incentive to get it built. (Unfortunately, toll road revenue is abused in both Houston and Dallas-Fort Worth, and the New York/New Jersey area is legendary for diverting toll revenue.)
For example, look at state route 73 in Orange County or the Inter-County connector in Maryland, projects which were nearly miracles to actually get built and could only be done as toll roads.
