Construction is underway on a St. Henry Dollar General store that will open in March, according to the company's corporate communications director Dan MacDonald. The 7,300-square-feet store is located just south of True Value Hardware on state Route 118. The company will employ about 10 people, MacDonald said. A new, similar store in Rockford is scheduled to open in October. Dollar General is building 635 new stores nationwide this year, MacDonald said. The company has 10,700 locations in 40 states.
