JAMESTOWN, N.D. (NewsDakota.com) – The schedule for road diet construction in Jamestown has been announced. Chris Hartwig with Ti-Zack Concrete Inc. reports that beginning next week, they’ll start conducting storm sewer work on five intersections. It’s estimated to take about three weeks for this to be completed and prepare for concrete crews. Hartwig reports that traffic lights will start coming down next week as well. Traffic lights at 3rd Street will be re-installed once that work is done in June. Once that’s complete, Hartwig says they’ll have crews start removing one quadrant of each intersection starting on 7th Street South and moving North up Main Street and then West. Electric work will also be conducted at this time.
