The Port Authority is set to reveal five possible designs for a new bus terminal.

They're expected to be unveiled tomorrow.

The Port Authority's 66-year-old Midtown terminal could get a face-lift — or a replacement.

The bi-state agency and representatives from New York and New Jersey agree on the need for improvements to the west side facility — especially with ridership expected to jump to 337,000 passengers daily by 2040.

Officials are now asking for an analysis of possible sites to build a new terminal, as well as additional locations, which could include New Jersey.

Moving forward the designs are expected to be presented for public comment.
