(Camden, OH)--The intersection of two highways in Preble County is about to undergo a major reconfiguration.  Beginning Wednesday, a year-long construction project gets underway at U.S. 127 and State Road 725 in Camden.  Alterations include a turn lane to be added.  That intersection was the site of a 2017 crash that killed three members of a family when a Centerville trucker blew through the stoplight.  Both highways will remain passable through the construction process.
