by Gabe BullardThe American Society of Civil Engineers has given the Louisville Metro Area a C on the latest infrastructure report card.Engineers looked at infrastructure in the seven counties in Kentucky and five counties in southern Indiana that surround Louisville. The C grade is the average for eleven categories. Some, like roads, bridges and dams, were in the D range, while the area received higher marks for inland waterways, energy and drinking water.Engineer Ted Niemann says the grades could be improved if area governments put more focus on maintaining existing infrastructure."We've been living too long on the 'out of sight, out of mind,' with that mindset," he says. "We need to be able to focus and pay it forward a little bit."Niemann acknowledges that many state, county and city governments do not have enough money to make routine improvements. Nationwide, the average infrastructure grade is a D.
