Document Description
Winter storms of 2005-2006 caused a slipout of Alderpoint Road at Post Mile (PM) 41.4 and separation of the asphalt surface at PM 41.6. A damaged 24-inch diameter cross-drain culvert at PM 41.4 backs up water at the inlet which creates a small seasonal pond around the inlet area. The project involves replacement of the existing 24-inch diameter cross-drain culvert and installation of a subsurface stabilization trench near PM 41.4. The project also includes construction of a stabilization trench under the roadway at PM 41.6.
