Changes in agriculture operations over the past 35 years are having a dramatic impact on Iowa’s roads and bridges. The average size of an Iowa farm has increased to 352 acres in 2003, compared to 237 acres in 1970. Modern agricultural practices have also produced higher yields per acre, which means more grain to haul to market. In order to increase efficiency, farmers are beginning to use larger capacity wagons hauling more bushels per trip to the elevator, and using much heavier equipment in their farming operations. This trend is stressing Iowa bridges beyond the current capabilities to maintain them.
