Managing Upgrades to Structures and Accessibility

The Madison, Grant, and Lincoln make up American Plaza Towers while a four-level underground garage between them underneath the plaza provides access to the towers. With the four floors of that underground structure are 402 parking spaces, totaling approximately 250,000 square feet. Its repair and maintenance required the removal and replacement of the plaza roof level paving and planters.
