A year ago Gov. Mark Dayton set up an advisory panel to study the long term needs of Minnesota's transportation system. It is an issue that has needed a lot of study - for years now, the revenue raised through the gasoline tax and other travel-related fees has fallen far short of what is needed to repair, maintain and improve the state's roads and bridges. The state Department of Transportation has had to fund only the most high-priority projects. Pushing road and bridge repairs down the road, for want of a better clich, only assures that little jobs will turn into bigger, more costly jobs.
