In September 2019, the Capital Program was released by the MTA and approved by the MTA Board; it includes $159.6 million for improvements in the tunnel, $386.9 million in funding to replace the viaduct, and $348.8 million to repair the Grand Central Terminal trainshed. The viaduct and trainshed projects will be completed in multiple stages and will be completed in future capital programs. The first stage of the viaduct project consists of inspections, design work, and the replacement of the most critical portions of the viaduct. During the first part of the trainshed project, the first section of trainshed will be replaced and design work will be completed for the next part. The trainshed repairs will address the deterioration of the trainshed's roof and its support due to the intrusion of water and salt from Park Avenue. The Park Avenue Tunnel project will construct four new emergency exits in two locations.
