Trabuco Road Improvements 

Work will be performed on Trabuco Road, from Jeffrey Road to Sand Canyon Avenue, Monday, July 15, through Friday, September 27, from 7 a.m. to 7 p.m. The work will be performed Monday-Friday during this date range. Asphalt pavement, curbs and gutters, curb ramps, and sidewalk will be removed and replaced. Traffic signals will also be modified.
