County Experience

At Interstate Engineering, we realize counties manage many miles of road with limited resources. With this in mind, we offer solutions that optimize County resources. We also strive to meet the needs of an aging infrastructure.

We approach each project the same way, with efficiency and professionalism in mind. Incorporated in 1976, Interstate Engineering has grown to 16 offices across the region. Our diverse network of resources allows us to achieve your expectations every single time.

We perform extensive county work throughout Montana, Minnesota, North Dakota, South Dakota, and Wyoming. We have experience working with federal and state regulations. This includes document preparation to meet environmental regulations and design and construction engineering. We have worked on roads, bridges, structures and drainage projects. Interstate Engineering’s knowledge ensures a completed project to applicable standards.
