- State Route 121 Bridge Railing Upgrade Project
- Description
- The California Department of Transportation (Caltrans) has prepared this Initial Study with Negative Declaration (IS/ND) for the State Route (SR) 121 Bridge Railing Upgrade Project (Project). Caltrans would upgrade the bridge railings at Yellow Creek Bridge (approximately 44 linear feet) (post mile [PM] 6.52) and at Arroyo Seco Bridge (approximately 160 linear feet) (PM 8.43) on SR 121 in Sonoma County, California. The Project would also include widening Arroyo Seco Bridge approximately 24 inches on each side (for a total of approximately 48 inches) to accommodate the updated bridge railings, removing the metal beam guardrail and alternative flared terminal systems, and installing Midwest Guardrail System and alternative in-line terminal systems, constructing concrete anchor blocks, and installing vegetation control.
