Daviess County Commissioners

Daviess County, Indiana ranks in the top ten in the U.S. in terms of the size of its Amish community. The mix of horse-drawn buggies, passenger cars, and commercial trucks along Cannelburg Road has led to accidents, prompting Daviess County to ask Lochmueller Group (Lochgroup) to look for alternatives to improve safety. In addition, the horse traffic actually causes the largest impact to the roadway with extensive damage that requires more frequent repairs.

Lochgroup’s solution was to widen the driving lanes and add wide, paved shoulders to be used as buggy lanes. Initially, Daviess County wanted to use concrete pavement for the driving lanes because it would require less maintenance. The Amish community, however, requested that the buggy lanes be constructed of asphalt, due to slipping of the hooves that can occur on a concrete pavement.

Lochgroup worked with INDOT’s pavement design and maintenance divisions to propose an asphalt pavement with steel-furnace slag aggregate for the surface of the buggy lanes to maximize the shoulders’ ability to withstand the wear from the horses’ hooves.
