Northern Interstate Construction, Inc. was founded in 1985 by our current President and Vice President, Bruce and William Johnson. In the last 30 years a lot has changed – technology, government regulation, and the materials we use in our daily lives. But, one things remains unchanged – our dedication to doing the best work we can. We keep an old fashioned attitude about work, and that's that it needs to be done when we promised. More and more, that means relying on new technologies, larger machines, and an engineer's state-of-mind.
