Rapid City Office Being Interactive: Creek Clean Up

The Interstate Engineering Rapid City team recently participated in the 2026 Rapid City Creek Clean Up, continuing a valued tradition of community involvement and environmental stewardship.

Team members volunteered their time to help remove debris and improve the health and appearance of Rapid Creek, an important natural resource and community gathering place. Their efforts not only contribute to a cleaner environment but also reflect Interstate Engineering’s ongoing commitment to being #InterActive and to engaging with the communities we serve.

Events like the Creek Clean Up are a simple yet meaningful way for our team to give back, connect with one another outside the workplace, and make a tangible impact in the community. We’re proud of the Rapid City team for representing Interstate Engineering and helping care for a place that holds significance for so many.

Thank you to everyone who participated and helped make a difference!

The Rapid City Office can be located at 1635 Deadwood Ave.
