Another Port Authority project involves redeveloping LaGuardia Airport, replacing three existing terminals with a single terminal. Terminal B would be demolished and terminals C and D would be merged. Some of additional taxiways are to be built, and transportation around the terminals would be reorganized. As part of the reconstruction, the AirTrain LGA people mover system would be built between the airport and Willets Point, Queens, where there would be connections to the Mets–Willets Point station on the Long Island Rail Road and the Mets–Willets Point station on the New York City Subway. The redevelopment is expected to cost $7.6billion in total. Construction started in 2016, and the first part of the new terminal is expected to open in 2021, with completion in 2026. The AirTrain would start construction in 2020 and be completed by 2022.
