ELMA – This town is all about building bridges – even though you normally won’t find an expanse of water much wider than Mead Creek on the northwest edge of town. There’s one covered bridge, an old rail head viaduct over Main Street that is now part of a recreational trail. That has now become a community symbol, a motif of what this Howard County community of a little more than 500 is trying to accomplish. In fact, the name of the town’s nonprofit community betterment organization is The Bridge Inc. It’s a coalition of people that have put together a community complex project now underway in a closed elementary school building. Elma is one of a handful of Iowa communities involved in Shrink Smart, an Iowa State University research project begun in 2017 that examines how towns with decreasing populations keep their quality of life.
