I experienced this today when taking my middle-schooler back to school from a Dr. appointment. It’s one lane from before Chesnut all the way to Brookrun!
Here’s the announcement I just received from PCMS:
Please be aware that the City of Dunwoody will begin paving the area of road from Barclay to Brookhurst on North Peachtree Road. The paving will begin at 9:00AM and end at 2:00PM The paving will be in process for the entire week of August 22, 2011. This may cause a 10-15 minute delay while the paving is taking place.
