Document Description
Note: Shorten Review Caltrans plans to improve safety at the intersection of Madrone Ave. and State Route 84 (Old Gravenstein Highway) in Sonoma County by including a left-turn lane in each direction. The project will widen the pavement several feet northwards towards Derby Lane to make the needed room. In doing so it will extend drainage culverts to the edge of the new pavement. Drainage ditches that the project will fill will be replaced with new ditches and culverts.
