Seasonal restrictions apply during major events like the the Palmer Holiday Exhibition and the the Palmer Holiday Marathon, which may impact routing and scheduling.

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