Abstract: The West Virginia Department of Highways (WVDOH) is using a two stage channel excavation concept to mitigate the hydraulic impacts of relocating U.S. Route 119. The selected highway alignment begins just north of Williamson, where it travels north, following the alignment of the Tug Fork river for approximately eight miles, then veers eastward away from the river just north of Nolan, West Virginia.The goals of the project are: To provide additional channel conveyance by means of flood plain modifications designed to mitigate the hydraulic impacts on the water levels upstream of the project. To leave as much of the natural channel undisturbed as possible. To provide additional wetlands mitigation and improve the river's fish and wildlife habitats.
