Morgantown lock dewatering reveals severe damage
Chris Bushaw, Marty Litzinger, and Roy Melius jack-hammer concrete. Fixing the sills required installing an upstream needle dam and downstream poiree dam so that the existing miter gates could be removed and crews could work in the dry. Jack-hammering, concrete placements, custom fabrication to replace 50-year-old parts, and hard work ensued.
