From Linda Moraski

South Street in Needham between Charles River and Chestnut Streets will be closed until November.  There is NO through access at this junction and they will NOT be letting cyclists through.  

There are easy work arounds but if you are leading or planning a ride through this street, you will want to have the detour worked out ahead of time….and also, don't waste your time riding down the road to see if you can get through….you can’t.
