Fine, I'll take it a step further and say a full cap doesn't appear any less feasible or expensive to me than what is shown.

The design shown is a bunch of wild angular cantilevers at varying elevations that seem mostly focused on supporting a trail through the area, and creating a grade-separated crossing to some mysterious egglike structure on the south side of Peachtree St. The latter item imo shouldn't be part of the project scope at all, and the grade separated pedestrian crossing to it seems like a really expensive tidbit that ultimately adds very little to the overall experience of the park.

Look up an aerial of Klyde Warren Park. Much less fancy design.
