After a short “false start” halted by ice in the channel and a damaged silt curtain, dredging production in the DetroitHarbor channel appears to be back on track.
Although Roen resumed project digging Tuesday, April 7, only a small amount of spoils were dredged before laying up for silt curtain repairs, and by then, broken ice filled the channel. Digging resumed again Sunday, April 13, and there has been steady production since then.
This northernmost section, according to Foth Construction Manager Ken Aukerman, seems easier to dig because it consists mostly of clay and mud, with less stone. A third material scow was towed to DetroitHarbor by a Roen tug Friday, April 19, from Sturgeon Bay. It was added to the scow rotation upon arrival. This added vessel is intended to help boost daily production. Aukerman noted that final yardage from last fall, estimated then at just over 50 percent, turned out less than the actual of 60 percent, based on calculations made using the bottom survey reading taken in December. Aukerman noted that “yardage based on scow counts appears to have been conservative.”
Island motorists will note many locations where blacktop has heaved and potholes were made. Orange caution signs warn motorists of those spots, found especially along the heavily used trucking route on Airport, Lakeview and East Side roads. The Town of Washington road crews are using gravel material hauled to the Island in Door County Highway Department trucks to fill in those holes. It will be late summer, most likely, before a blacktop plant is transported here and more permanent road repairs and improvements can be made.
