The Town of Danville will replace a drainage culvert on Diablo Road, which will be closed to through traffic from Alameda Diablo to Avenida Nueva beginning March 23. The replacement project is necessary to maintain safe travel on Diablo Road and integrity of the Town drainage system, as the existing culvert pipe is at the end of its 60-year lifespan.
Town engineers inspected the culvert pipe while making storm-related repairs to the roadside slope in January. They found the pipe to be flattening, causing slope erosion and a dip on the surface of Diablo Road. The approximately 21-day project will include trenching across Diablo Road, removal of the outdated culvert, fabrication of the new culvert on-site, and installation of the replacement. The project is being planned with efficiency of time and resources, and full closure of Diablo Road will result in the shortest project duration and most efficient replacement of the critical drainage infrastructure.
Town staff have identified the potential project duration of March 23 to April 13 to make best use of nearby school break schedules. Diablo Road is expected to be closed for the duration of the project, from east of Alameda Diablo to Alameda Nueva. Additional details, including detour routes, project updates, and local resident access will be available at www.DanvilleTownTalks.org/DiabloCulvert.
