The Nevada Department of Transportation has substantially completed a project to enhance storm drainage, help preserve water quality and reduce erosion on U.S. 50 in south Carson City. The project replaced more than 50 storm drains and drop inlets, and enhanced roadside slopes and curbs and gutters on U.S. 50 from the South Carson Street/Spooner junction to Tahoe Golf Club Drive,about four and a half miles up U.S. 50. The drainage systems carry storm water into the Clear Creek Watershed on the south side of U.S. 50. The $1.2 million project by M-K-D Construction started in June. The improvements are part of the Clear Creek Erosion Control Program.
