(Preble County, OH)--The Whitewater Valley’s first significant highway project of 2024 is about to get underway.  It’s on State Route 122, which connects Boston and Eaton.  Beginning in a couple of weeks, crews will completely remove all layers of highway and replace it.  The project is an extension of one that began last year’s repaving, moving from west to east.  122 will be reduced to one lane for about a month and a half.
