This week CSG released a new Capitol Facts & Figures policy brief highlighting efforts to increase or otherwise change State Motor Fuel Taxes in a number of states this year. Although some earlier this year predicted that several states, faced with significant infrastructure challenges and limited options to raise needed transportation revenues, would increase their gas taxes in 2011, that hasn’t yet come to pass. Instead, escalating gas prices caused by instability in the Middle East and North Africa have meant that gas tax increases are still just as politically unpopular as they were in 2010, when no state adopted one. But that doesn’t mean there haven’t been some interesting developments this year. Here are some updates on recent activity in South Dakota, Arkansas, Oregon and other states.
