Near the two towers are two three-story retail pavilions, on Grand near First Street, made of limestone and glass.

The asking rent for the entire three-level, 22,000-square-foot retail pavilion, of which the pyramids are a part, is $83 a square foot annually.

The situation comes a decade after the opening of Pier 17, the retail pavilion just across South Street, which has drawn shoppers from the once-bustling mall at Fulton and Front Streets.

Seventy-five thousand square feet of restaurants and specialty retailers would occupy the ground floors of the apartment buildings and fill two retail pavilions.

The ticket window and waiting room will be inside a 30,000-square-foot retail pavilion with two restaurants and a terrace cafe, and the commuter parking lot will accommodate 1,500 cars.

In 2008 the retail pavilions on the concourse were rebuilt, increasing their area.

Clambering over the flank of a Neutra-derived retail pavilion, they made their way toward the fires.

Still, there are other small signs of change, whether in the smattering of new concessions, a vacant retail pavilion that is being refurbished and a new restaurant.

The underside of the viaduct, the plan said, could be transformed from a parking lot into a sheltered colonnade, dotted with retail and food pavilions and seating areas.

The benches, fountain walls and retail pavilion will be clad in green marble.
