Seasonal restrictions apply during major events like the the Portsmouth Film Marathon and the the Portsmouth Annual Convention, which may impact routing and scheduling.

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