Some government officials are concerned that high costs related to the Port Authority’s stringent security requirements for the development site at West 37th Street and Ninth Avenue are threatening the real estate deal and planned development of the site. The Port Authority agreed to sell the development rights for the site, which is currently occupied by several Lincoln Tunnel entrance ramps that will need to be covered by a platform, two years ago to developer Dermot Company, but the deal has yet to close. Dermot has planned an 800-unit residential complex called the Hudson Mews. Officials are especially concerned since the development, which will include covering the on-ramps and creating a park, will help to bridge the eastern portion of the Hudson Yards area with the western portion.
