A brand new $ 3 million assault plant will soon be finished at the Murphysboro Industrial Park. The Samron Contracting facility was approved to break ground last month. City officials say the new plant will create 30 new jobs and 10 temporary construction positions. The plant is expected to begin operations in June and produce 60,000 tons of asphalt a year. Officials say they are already brainstorming ideas to open another plant in the city.
