For folks taking MARTA, they’ve scheduled maintenance on the Peachtree Center station escalators for Labor Day (Dragon*Con!) weekend. From their Facebook page:

ESCALATOR ADVISORY AT PEACHTREE CENTER STATION: Beginning Wednesday, August 8, 2012:

On Wednesday, August 8, MARTA will close the two long escalators that serve the Food Court entrance via the Northeast concourse at our Peachtree Center station.

Both long escalators will be taken out of service at the same time (August 8). The complete replacement and repair is expected to be finished by mid-October.

In the meantime, MARTA customers may use the Northwest exit (Post Office/AmericasMart) or elevator and exit the Peachtree Station on the sidewalk across the street from the Food Court. Or, they may exit with the Southeast escalators or elevator and walk north on the same side of the street as the Food Court.
