As 2012 dawns, there is still no agreement on new legislation to authorize federal surface transportation programs. The previous legislation, known as SAFETEA-LU, officially expired in 2009 and the programs have been operating under a series of temporary extensions since then, the latest of which expires at the end of March. The primary cause of the delay in approving a SAFETEA-LU successor is of course money. The federal gas tax in recent years has not produced the kinds of revenues it once did and faces an unsustainable future. The Highway Trust Fund, which relies on the gas tax, has required frequent infusions of cash to continue programs. Yet the still struggling economy and other factors have made efforts to seek new revenues to fund transportation politically impossible. While some state governments have used this time of uncertainty at the federal level to move forward on their own to creatively fund infrastructure improvements, others appear to be hunkering down, making the decision to do only maintenance on existing facilities and hoping they can ride out the lack of revenues, shaky economy and growing infrastructure needs until better times are upon us.
