Maggie Daley Park

This guide to Maggie Daley Park in Chicago traces the decades before it existed, when this corner of Grant Park was Richard J. Daley Bicentennial Plaza, a green roof laid in 1974 over a parking garage on old rail yards. It follows the rubber membrane that slowly failed beneath the lawns above, and the crews who had to strip the whole plaza back to bare concrete, trees, lawn and wildflower beds, to fix it before the park reopened in 2014.
