With the passage of the FAST Act by Congress in late 2015, states have some of the long-term certainty they have long sought in the federal transportation program. But can a mostly status quo, five-year transportation bill help states make up for years of inadequate investment in the nation's infrastructure. More than likely, more than a few will still feel compelled to follow in the footsteps of eight states that raised gas taxes in 2015. Some may also turn to tolling and public-private partnerships to help fund projects, although those tools in the toolbox have seen increasing scrutiny and criticism in some parts of the country. State officials face a variety of other challenges as well including how to plan for the technological and demographic changes that could radically alter the transportation landscape in the years ahead and how to deploy and enhance the kinds of transportation options that will make communities into livable, sustainable, economically vital places. Here are my top five transportation issues for 2016 along with more than 500 links to resources from CSG and a variety of other sources where you can read more.
