From the Queens Chronicle:
The mosaic tile discs encircling Flushing Meadows Corona Park’s Dinkins Circle are falling to bits — and in some cases they may not return.
The Parks Department has cordoned off the tile disks, which commemorate the park’s two World’s Fairs, to keep pedestrians from continuing to trample on them.
“Some areas that cannot be repaired will be replaced with hex block pavers,” said a Parks Department spokesman. “Cars are not allowed into David Dinkins Circle to prevent further damage to the mosaics.”
