ALBANY, N.Y. (AP) — Critics are throwing shade at Gov. Andrew Cuomo's pricey plan to install high-tech, color-changing lights on New York City's bridges, questioning whether the investment is the best use of public money. A government watchdog group this month called for a state probe into what it says are conflicting explanations for how much the lights cost and where that money will come from. De Blasio, who has frequently sparred with his fellow Democrat, urged Cuomo to reallocate the money for emergency repairs on the subway system, which has been plagued by mounting delays, derailments and other problems caused by decades of neglect. Despite initial reports that the Metropolitan Transportation Authority would foot the bill, the state now says the money will come from economic development funds and proceeds from the state's Power Authority, which often works on big energy efficiency projects.
