Spearfish Office being InterActive – Treats Main Streets

The Spearfish Interstate Engineering office volunteered as crossing guards for the “Treats on Main” event, hosted by Visit Spearfish and the Downtown Business Association (DBA). Held annually on Halloween, this event allows children and families in the Spearfish community to trick-or-treat from business to business throughout the Historic Downtown district.

By assisting with pedestrian safety, the Spearfish office helped provide an extra layer of protection for community members participating in the event. It also offered our team a meaningful opportunity to engage with and support the community we serve.

The Spearfish Office can be located at 120 Industrial Drive Suite 2.
