Innovation is becoming a key to sourcing funds for state transportation projects, and the Minnesota Department of Transportation is considering doing just that by possibly engaging in public-private partnerships. One estimate suggests the state would need more than $13 billion in the next 20 years just to repair existing road and highway infrastructure -- far more than the state can handle. "Transportation always creates some construction jobs, but how can you get great job creation performance out of each project?" said Phil Barnes, an MnDOT official. "That's what excites me about moving toward more public-private partnerships."
