A decade ago, then-Gov. Bill Ritter assembled a bipartisan commission to study an issue of growing concern to state leaders: transportation. They called it the “quiet crisis.” Colorado’s roads weren’t yet in terrible shape. But it was clear what was on the horizon: Declining revenues coupled with booming population growth had put the state’s motorists on a collision course with potholes and congestion. “It is a crisis we can no longer ignore,” the commission concluded in its final report, published in January 2008.
