Lane and roadway shoulder closures will be in place starting today through Thursday, April 20th on I-80.  The Nevada Department of Transportation needs the time to repair potholes and roadside slope erosion. Westbound I-80 will be reduced to one lane near the Nevada-California stateline from approximately 8 a.m. to 4 p.m. for clearing and repair of a roadside slope which loosened during winter storms earlier this year, bringing rock and debris to the roadside guardrail. Weather dependent, periodic overnight lane closures will also take place between 7 p.m. and 6 a.m. Monday evening through Friday morning on both directions I-80 west of Reno for continuing pothole repairs.  Additional single, intermittent lane closures may occur in future weeks as weather-related repairs continue.
