Over the past 18 months, Port Authority staff, working with consultants from Parsons Brinckerhoff and Skanska USA, among others, developed five options to replace the terminal [PDF]. Only one of them, which would take 11 to 15 years to complete, accommodates the projected 35 to 51 percent passenger growth increase by 2040 while also continuing to serve inter-city buses. Naturally, it is the most expensive option, with consultants putting the pricetag at $10.5 billion.The other options would relocate inter-city buses to an unspecified bus terminal elsewhere. All five would add bus staging areas to reduce traffic on surface streets, and most would require construction of an interim facility to handle passengers while the bus terminal is torn down and rebuilt. The least expensive option of the bunch, at $7.5 billion, would actually handle fewer passengers than the existing terminal.
Why the high costs? The structural slabs that make up bus ramps and decks are deteriorating and will need to be replaced completely in 15 to 25 years.
“The heaviest structural steel pieces made in the world today will be required for this project, in the thousand of tons,” said Mark Gladden, a project executive at Skanska. He said there are only two places in the world that manufacture this type of steel, which will have to be custom-ordered.
Building ramps and structures that can accommodate thousands of buses each day above the portals to the Lincoln Tunnel, all while keeping existing passengers moving during construction, is a tall task. “There has been some comparison to high-rises and parking garages,” Gladden said. “That is a comparison that should not be made.”
Gladden compared the bus terminal replacement to the UPS Worldport in Louisville, Kentucky, which handles virtually all of the shipping company’s domestic air freight. Built 15 years ago, he said, it cost $850 million. Taking inflation and construction cost increases into account, the project would likely cost $1.7 billion today. Moving the project to New York, with its higher construction costs, would double the price tag to $3.4 billion. The UPS project didn’t have the steel requirements and logistical challenges posed by operating a bus terminal in Midtown Manhattan, Gladden said, which contribute to the additional costs.
