Greenwood, IN, city officials have announced plans to turn the site of a former Prairie Materials concrete plant into a wetlands area and a trail. The project is tied to plans to turn a local road into a major boulevard that can handle traffic from a planned Interstate 65 exit. Greenwood plans to partner with the Indiana National Guard to demolish the plant this fall, so that utilities can be relocated in time for the road widening in two years. The National Guard wants to salvage what materials it can from the plant and use them to help create realistic training environments at one of its training facilities.
