The U.S. Senate Wednesday passed a long-awaited, 18-month, bipartisan, $109 billion bill to authorize federal surface transportation programs on a vote of 74 to 22. Attention now turns to the House, where leaders could decide to take up the Senate measure or seek to resurrect their own five-year, $260 billion plan that has so far failed to win the same level of support. Meanwhile the March 31st deadline when the latest SAFETEA-LU extension expires looms large and many believe another short-term extension will be needed to give time for the House to act and for lawmakers to work out details of a final bill. But, as U.S. Transportation Secretary Ray LaHood told a Congressional committee today, that scenario is complicated by the start of the road construction season when states must have some certainty that the money will be there to pay road contractors over the next several months and beyond. Still, despite the challenges ahead and the Senate bill’s shortcomings, many are praising both its passage and its provisions, many of which could have a huge impact for state governments for years to come. Here are some notable elements of the legislation.
