Years Since Last Gas Tax Increase

In the map, we have color-coded the number of years since each of the 50 states last raised taxes on gasoline. On the positive, side, quite a few states managed to raise rates within the past year, although California adjustment was actually part of a revenue neutral gas tax/sales tax scrap. On a negative rate, about one-half the states have not raised their gasoline taxes in more than a decade. Also, by special request of Commissioner Haggerty, I've included a bonus map which represents the proposed BART system that was presented to Alameda, Contra Costa, and San Francisco voters at the election approving construction of the system in November 1962.
