Denver Post: State transportation needs more funding

From Denver Post: 

Coloradans own a conservatively estimated $500 million per year unfunded liability on public bridge, highway, interchange and tunnel infrastructure.  While a staggering sum in any single year, the cumulative effect year after year undermines road safety and our state's economic recovery. That Colorado's people, families, businesses and leaders continue accumulating a $500 million annual deferred maintenance debt is unsustainable.  That $500 million annual buildup, however, disguises the full magnitude of the "quiet crisis" Coloradans now confront.
