The terminal in New York City is the drop-off point for commuter buses from the Lehigh Valley, northwest New Jersey.
Officials have awarded a contract to study and create a plan to improve the Port Authority Bus Terminal in New York City.
Port Authority officials say the terminal serves more than 65 million people a year and is at capacity during rush hours.
It is the drop-off point for commuter buses from the Lehigh Valley and northwest New Jersey.
The study will include plans to possibly replace the terminal or repair and improve it. Construction would have to be phased in to prevent disrupting operations.
Officials will also examine ways to create a new bus staging area on Manhattan's West Side to limit the amount of buses idling on city streets.
