Department of Transportation officials have estimated that Nebraska will need $11.2 billion for improvements to the highway system, or $16 billion when adjusted for inflation. With a current annual budget of $500 million for roads that adds up to about a $6 billion budget gap over the next 20 years. Kyle Schneweis, director of the Department of Transportation, had a positive outlook though, when discussing the projections at a meeting with state lawmakers. He cautioned that revenue sources could significantly change in that time frame. Right now part of the gas tax is going towards maintenance of Nebraska roads but with the advent of electric cars, ride sharing, and autonomous vehicles revenues from the gas tax may decrease significantly.
