Traffic Advisory For Sleeper Street (Friday) & MCEC

On Sleeper Street, MacKay will be repaving the western side of the street Friday, September 25, 2026. The repaving will start as early as 5am to get ahead of the heavy weather headed our way. The work zone will remain as is for the repaving and access on Sleeper will not be changed.

The ASTRO – American Society for Radiology Oncology will be taking place at the Menino Convention and Exhibition Center from Saturday, September 26 to Wednesday, September 30. 

We will be welcoming 13,000 daily attendees to the neighborhood. 

Expect increased area activity, traffic, and limited parking. Transportation agents will be on site to make sure shuttle buses, taxis, and TNCs do not impede other traffic or stop at locations that will cause safety concerns for the passengers and/ or other motorists.
