Despite President Donald Trump’s repeated commitment to building new infrastructure, the U.S Department of Transportation (DOT) has withdrawn its cooperation from a massive $24 billion transportation project between New York and New Jersey, as reported by New York Daily News.

The Gateway Program Development Corporation planned to bring a new rail bridge, Portal North, to Newark as well as a new tunnel under the Hudson River that was meant to replace the existing, crumbling tunnel that suffered extensive damage from Hurricane Sandy. The program also looked to expand Penn Station and build new bridges to better connect Newark, New Jersey, and New York City. However, the DOT notified the Gateway’s board of trustees of their withdrawal last Friday.

“It is not DOT’s standard practice to serve in such a capacity on other local transportation projects,” read the letter to the Gateway board of trustees, which also counts Amtrak and board members from the New York and New Jersey Port Authority as members.

Plans to build the new tunnel have been in the works since the Obama administration, where a deal was struck so that New York and New Jersey officials would take on half of the costs while the federal government and Amtrak would undertake the other half. Trump had also included the Gateway program in his list of “Emergency & National Security Projects,” a list of about 50 national infrastructure projects that was first published in January by the Kansas City Star.

The Gateway project has been billed as one of the largest regional transit projects in the Northeast, one that would address the growing number of commuters from New Jersey as well as the region’s deteriorating infrastructure. The current two-tube tunnel linking New Jersey and Penn Station shuttle more than 200,000 riders daily. If one tube fails before new tunnels are built, capacity could be reduced by 75 percent, according to Amtrak.

The DOT clarified their withdrawal, saying that “the decision underscores the department’s commitment to ensuring there is no appearance of prejudice or partiality in favor of these projects ahead of hundreds of other projects nationwide,” in a statement to the Wall Street Journal.
