The segment of Dartmouth Avenue from Clarendon Place to Kingstone Road will turn one-way starting Friday, May 26, and will remain that way through the end of pool season at the Avondale Swim and Tennis Club (ASTC). During this time, only northbound vehicles will be permitted on that stretch of Dartmouth Avenue. The change is being implemented to create a safer environment for increased foot and vehicle traffic around the ASTC.
