The Nevada Department of Transportation is reminding motorists to anticipate minor travel delays during the American Century Championship golf tournament at the Edgewood Tahoe Golf Course in SLT on July 19-24, due to road construction on U.S. 50 in Lake Tahoe’s Cave Rock area. NDOT is building a 60′ x 27′ extension of the westbound, lakeside Cave Rock tunnel to enhance safety and reduce the potential of rock fall onto the roadway. Traffic has been reduced to one lane in each direction through the eastbound Cave Rock tunnel, with 25-mph speed limits.
