MDU Resources is Building a Strong America^®

A strong infrastructure is the heart of our economy. It is the natural gas and electricity that power business, industry and our daily lives. It is the pipes and wires that connect our homes, factories, offices and stores to bring them to life. It is the transportation network of roads, highways and airports that keeps our economy moving. Infrastructure is our business, and we are building a strong America.
