Construction of a replacement waterline on Hostetler Street in The Dalles will begin on Monday.  It will start at 10th & Hostetler and progress to 6th & Hostetler.    Road closures and detours with flagging leading to potential delays of up to 20 minutes are to be expected throughout the duration of this project.  Construction & road closures and detours will be segmental as construction progresses along Hostetler.  The first segment will be from 10th Street to 8th Street.
