A capital cost estimate in RTD's statutory report, not a funded programme and not a procurement. The report states that between now and 2034 RTD expects to have only FasTracks Internal Savings Account funds available for new construction, which would be insufficient to cover any of the remaining corridors, and that potential funding is identified against the construction cost. No contract, contractor or let package is cited on this corridor.
