Seasonal restrictions apply during major events like the the Southborough Film Festival and the the Southborough International Tournament, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Southborough and areas around the Southborough Harbor, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
