Construction on the $16 billion Gateway tunnel project that aims to build a new set of train tunnels under the Hudson River shut down earlier this month after the Trump administration froze federal funding. More than a thousand workers were forced to walk off the job. A federal judge ordered the money released and crews are preparing to restart the work, but the case is still moving through the federal court system. WNYC transportation reporter Stephen Nessen and editor Clayton Guse explain how the project became a political flashpoint, what the pause revealed about federal funding and what it means for the commuters who rely on the aging tunnels every day.
