That portion of the highway will remain closed into next year. With this work complete, the focus shifts to State Route 190 outside of Death Valley National Park between Olancha and the junction of State Route 136. As pictured to the left, benched construction reshapes the hillside to look like stairs or stadium seating that is then covered with rock or dirt fill to stabilize the slope, allowing it to better withstand heavy loads and erosion from future weather events. At the recommendation of Geotechnical Engineers from the Caltrans Headquarters Division of Engineering Services, the contractors used benched construction to secure the steep hillside at two locations that were washed away by flash flooding. In addition to pavement repairs, the project contractors, Fisher Sand & Gravel Co., restored and restructured the hillside along parts of the highway. After more than two months of repair work, the roadway through this area-known as Argus Grade-has been restored. Traffic control measures had been in place since October 15 between the park's western entrance and Panamint Springs to accommodate repairs to the damage caused by Tropical Storm Hilary earlier this year. BISHOP - Around-the-clock one-way traffic control is no longer in effect for State Route 190 in Death Valley National Park.
