The Missouri Department of Transportation (MoDOT) expects revenues to reach $17.3 billion during the next 20 years, 91 percent of which is legally required to be spent on roads and bridges. The remaining $1.5 billion will go toward transit, aviation, rail and waterways. The investment falls far short of the $70 billion of transportation needs and wants identified by residents. It also represents a funding gap compared to years past. In 2009, $1.8 billion was allocated to transportation; that amount shrunk to $1 billion in 2013 and is expected to be $425 million by 2019. Meanwhile, transportation maintenance costs continue to increase and the fuel tax and other sources of revenue are not keeping pace with inflation.

MoDOT has committed to saving $512 million in operating costs from 2011 to 2015, and another $117 million each year thereafter. But to maintain and expand the state’s  transportation system, the department says Missourians must vote for more taxes or higher fees.
