Weather permitting, work will begin March 26 to replace a state highway bridge over the Middle River along Route PP in southern Callaway County.
Route PP is located between Missouri 94 and Route BB, and the bridge is west of County Road 470.
The bridge will be closed to traffic for about two months during construction.
The Missouri Department of Transportation has designated state roads as detours around the work area. The detours are along Missouri 94, Route AA and Route BB.
