The Tarkio Board of Public Works and Professional Wastewater Services of Shenandoah, Iowa, have been working on a sewer line issue for the past week. The line that crosses underneath Hwy. 59 between McNary Street and Broad Street had cracks that needed to be fixed. Instead of digging up the highway and causing major traffic delays, the workers were able to use cameras to find the cracks and then fix them using a cured-in-place pipe patch that actually patches the pipe from the inside. The weather has slowed work up a bit, but it was hoped that the project could be completed this Tuesday. McNary Street from 10th to 11th Streets has been closed during the work.
