"RTD also is using a lower forecast for sales-tax collections, which are a key component of the revenue stream that will pay for FasTracks, the nation's most ambitious mass- transit expansion program.
The agency now is forecasting that it will have about $4.2 billion available from tax collections, federal funds and other sources to build the project by 2017 unless metro Denver voters approve a doubling of the existing 0.4 percent FasTracks sales tax in November.
Last year's revenue forecast was $4.8 billion."
RTD expects to be about $2.5 billion short of what it needs to complete the system by 2017.
