The Idaho Transportation Department (ITD) has put together a $579 million budget for fiscal year 2011, which begins in July. 55% of the money included in it comes from the federal government.
Plus, they say they've saved a boatload of money on the GARVEE program due to construction costs being down, etc. etc. I'm too tired to sumarize anymore, you're going to have to read the Idaho Reporter article yourself.
