In March 2016, the city released preliminary plans for a replacement structure, paid for by a $970,000 federal grant. Three structures would be built: a new garage with the same number of spaces, a "justice center" with a new Quincy District Court, and an office building for the National Park Service and its bus shuttle to Adams National Historical Park. The garage would have street-level retail locations. The busways would be relocated to the Burgin Parkway side and a roof added; the kiss-and-ride dropoff lane would remain on the Hancock Street side. The project is estimated to cost $52 million; the city proposes to use $10 million in state money approved in 2014, $20 million in federal grants, and $22 million from a private partner who would operate the facility for several decades. No city money will be used to pay for the project.
