San Luis Obispo/Santa Barbara Centerline and Edgeline Rumble Strips

Caltrans District 5 is forecasting a project to install centerline rumble strips (CLRS) and edge line rumble strips (ELRS) across San Luis Obispo and Santa Barbara Counties. The work is focused on Route 166 in both counties, Route 33 in San Luis Obispo County, and Routes 154 and 246 in Santa Barbara County. The primary objective is to reduce the frequency and severity of crossover and run-off-the-road collisions, utilizing rumble strips as a low-cost countermeasure for the benefit of the traveling public. The scope of work includes the installation of rumble strips at specific postmile locations and spot pavement reconstruction using a dig-out method to replace deteriorating asphalt. These dig-outs are specified to be 2 feet wide and up to 5 inches deep. All activities must occur within the Caltrans Right of Way and adhere to strict environmental and operational standards, including the use of heavy-duty trucks meeting CARB 2007 or cleaner certification and scheduling delivery trips outside of peak commute hours. The project is categorized under NAICS code 237310 and has been determined exempt under CEQA and NEPA regulations, as it involves maintenance of existing facilities without the addition of new lanes or structures.
