Coldfoot to Deadhorse Long Haul Fiber Project Segment 3 MP 245‐300 of the Dalton Hwy ~51.7 Miles.

Successfully installed and restored landscape to original condition on over 40 miles of 2 separate 1 ¼-inch fiber optic conduit HDPE conduits, as well as approximately 75 slack or splice hand hold boxes for a new back bone fiber line in remote areas of northern Alaska. The third segment portion of the system is ongoing (less than 10 miles remain), with an expected final completion of June 1, 2017. Ongoing phases of work will later tie into both phases 1 thru 2 and 4 (ongoing), as well as with AT&T’s existing southern cable route (Fairbanks to Coldfoot). This will form a complete system, thus providing for an advanced high speed voice and data network. Once completed in full, this system will connect Fairbanks, Alaska to the remote oilfields in Deadhorse and Prudhoe Bay, Alaska.

During DCC’s installation of the new system, major logistics challenges would require both vast advanced planning and equipment/parts redundancy. Parts of the route spanned across vast mountain passes, rivers, and some of the most challenging soil conditions in the world, to include frozen and unfrozen permafrost, solid rock, swamps and even subzero temperatures. As it was often necessary for DCC personnel to transverse multiple environments, terrain, and soil conditions, a large mix of specific specialty equipment for this project was employed. Specialty equipment included but is not limited to the following: a 1150 Tesmec rock saw for pre-sawing of frozen and rocky areas, Vermeer 1150 chain trenchers and plows, Bron 150 hydrostatic vibratory plows, multiple small and large excavators 5 – 30 tons. This equipment required the support of trucks and trailers, as well as other specially equipment as needed.
