Eight states—Georgia, Idaho, Iowa, Michigan, Nebraska, South Dakota, Utah and Washington—raised their gas taxes in 2015. Two other states—Kentucky and North Carolina—made adjustments to their gas tax mechanisms to make revenues more reliable. The state of Delaware meanwhile enacted legislation to raise several vehicle and license fees in order to fund road repair and maintenance. And states such as Maine and Texas approved ballot measures that will result in more money going to transportation. All that activity surpassed 2013 when six states produced major transportation revenue packages. But despite all that activity and despite the fact that 2015 could see Congress approve a new long-term federal transportation bill, 2016 also could see a large number of states join the club, particularly if many of those states that have come close in recent years or have had processes in place to examine revenue options end up moving forward. Here’s a roundup of the states to watch in transportation funding next year and some additional resources where you can read more.

As I wrote last week, Tuesday was a big Election Day for transportation in a number of places around the country. Statewide ballot measures, for example, won approval in Maine and Texas and local measures were approved in Seattle, two Colorado towns and a handful of Utah counties. But it wasn’t just at the ballot box that transportation was a focus of policy decisions. The U.S. House of Representatives worked their way toward passage of a long-term transportation bill. And Michigan lawmakers approved a long-in-the-works, $1.2 billion road funding bill that includes the eighth gas tax increase approved by a state this year. Here’s a roundup of transportation-related election results and updates on some of this week’s other key transportation developments.

While 2015 may be an off-year for elections in most states, it has the potential to be an important one for transportation in a variety of places. Here’s a roundup of how transportation is factoring into this year’s key state contests and ballot measures.

The city of Denver and state of Colorado have seen their share of transportation successes in recent years thanks in large measure to regional cooperation, federal investment, a 2004 tax increase, partnerships with the private sector and some innovative thinking. But the city and state face numerous challenges in the years ahead that will severely test the transportation system, notably a burgeoning population, stagnant federal investment and limits to increasing taxes at the state level. Those were some of the messages state and local officials delivered to a group of state legislators from eight states at the CSG West Transportation Forum last month in Denver.

Eight state legislators from around the country, many of them transportation committee chairs or vice chairs in their respective states, attended the 5th Annual CSG Transportation Leaders Policy Academy May 11-13, 2015 in Washington, D.C. The academy, which took place during Infrastructure Week, included a tour of transportation projects in Northern Virginia, a keynote address by Maryland Secretary of Transportation Pete Rahn, a luncheon at the D.C. office of the American Society of Civil Engineers (ASCE), a standing-room-only briefing for Capitol Hill staffers on the importance of continuing federal transportation investment to state and local officials, a conversation with officials at the U.S. Department of Transportation, a dinner with representatives of two of the largest transportation-related membership associations—the American Road & Transportation Builders Association and the American Public Transportation Association and a briefing on the status of state exploration of mileage-based user fees. Attendees also took part in a transportation policy roundtable with representatives of ASCE, the American Association of State Highway and Transportation Officials, the U.S. Chamber of Commerce, Transportation for America, the Eno Center for Transportation, the American Trucking Associations and UPS. Finally, the legislators were able to take part in Infrastructure Week activities including Advocacy Day on Capitol Hill. This page includes photos from the three-day academy, the complete agenda for the event and links to web pages where you can read extended excerpts of remarks from many of the speakers.

July 1, 2015 marks a big day for the future of transportation funding in a number of states. Six states see their gas tax rates increase today, the result of not only 2015 legislative actions but also actions that took place in previous years as well as automatic increase mechanisms. Meanwhile, Oregon begins a closely watched program that could determine how transportation will be funded in the years ahead. And a number of state legislatures are in the process of completing work on major transportation funding packages as they prepare to adjourn for the year. It all sets the stage for a month in which Congress must come up with a plan to address federal transportation funding before a July 31st deadline.

A bipartisan group of senators this week introduced a six-year transportation authorization bill that proposes to increase highway spending by almost 13 percent and spread more than $2 billion a year among states to invest in freight facility improvements. But with a July 31 deadline fast approaching, Congress is still at a loss when it comes to how they might pay for such a bill.

James Corless is the Director of Transportation for America (T4America). Jeff Davis and Emil Frankel are Senior Fellows at the Eno Center for Transportation. All three were panelists at a May 12 transportation policy roundtable as part of the 2015 CSG Transportation Policy Academy. In these excerpted portions of their remarks to state legislators attending the academy, they discuss the past, present and future of the federal-state-local partnership on transportation.

Joung Lee is the Policy Director at the American Association of State Highway and Transportation Officials (AASHTO) in Washington, DC. He was among the speakers at a policy roundtable CSG hosted May 12 in Washington as part of the 2015 Transportation Policy Academy. During these portions of his remarks, Lee spoke to state legislators attending the academy about why the federal Highway Trust Fund faces insolvency again this summer and some of the options Congress could consider to address the situation.

Michigan voters Tuesday declined to support a ballot measure that would have hiked the state’s general sales tax, fuel taxes and vehicle registration fees to provide funding for dilapidated roads but removed the sales tax on fuel, which currently goes to other purposes. I also have a report from last week’s International Bridge, Tunnel and Turnpike conference on transportation finance and road usage charging in Portland, Oregon. I’ll bring you up to speed about CSG’s involvement in next week’s Infrastructure Week activities and look ahead to a conference next month highlighting public-private partnerships.
