Gov. Jerry Brown says that the tax increase will generate approximately $5.2 billion a year. That money will be earmarked to support California’s aging transportation infrastructure. This is the first gas tax increase in 23 years for California. Republican lawmakers argued against the increase in a state that already pays the highest fuel prices in the nation. President Trump has indicated that one of his priorities is to increase infrastructure funding by as much as $1 trillion through public and private investment.
