First Week of August
North Bank Lane was opened to through traffic this past week as worked slowed on the final temporary grade raise of Redd Creek. Following the placement of the 10â€™ culvert the previous week, the road was raised to the overload height where it will be allowed to settle for the next year before being cut down to the final grade. As the work at Redd Creek is nearing completion Tidewater Contractors and their fleet of trucks shifted their efforts to the much longer road grade raise at Fahys Creek. Traffic in this area of North Bank Lane was reduce to a single lane to allow fill material to be placed in a large ditch along the south side of the road. The large 15â€™ culvert to be placed under the road at Fahys Creek is in route from the manufacturer in Pennsylvania and is scheduled to arrive on August 16th. Placement of the culvert will require temporary diversion of Fahys Creek and personnel with the Western Federal Lands Highway Division and Tidewater Contractors are making final plans for the diversion. The North Bank Lane road closure at Fahys Creek will go into effect on August 11th and the road will remain closed for approximately two weeks to allow for placement of the culvert and raising the road grade. In the interim, all through traffic will be redirect to use Randolph Road, which connects North Bank Lane to U.S. Highway 101.
Efforts by Knife River Corporation to excavate new tidal channels and fill old agricultural ditches accelerated last week. They now have three 6-wheel dump trucks on site and two tracked dump trucks for working in wetter areas. At the end of the week excavation of the new Fahys Creek channel began near North Bank Lane and will proceed to the south. USFWS, Confederated Tribes of the Siletz Indians, and ODFW fisheries biologists continue to monitor filling of ditches and rescue fish and amphibians. On a single day last week, more than 1,500 rough-skinned newts were successfully moved out of the construction area along with lesser numbers of northwestern and Pacific giant salamanders, and red-legged frogs.
Complications continued with the east bore for undergrounding the electrical transmission line under the Coquille River that would not allow the conduit to be successfully pulled through the bore. During the week a redesign of the second bore was developed that will include installation of steel casing the length of the bore. Work is being delayed while the 10â€� casing is acquired and transported to the site.
