Warren County is moving forward with a possible expansion of its jail, but with a couple of changes.Bids will be taken on architectural services and the estimated cost of the project has increased to $7.5 million. The county Building and Grounds Committee met to discuss the issues.“It’s a 250-bed expansion. Approximately 30,000 square foot would be added to the jail and we have to approve this in order for Financial Management to consider it,” said Commissioner Carl E. Bouldin, committee chair.
