Although the City's Traffic Engineering Division attempts to keep the community abreast of all construction activity to main streets and roads within the City, some activity is executed by other agencies (Caltrans, PG&E, Contra Costa County Public Works, etc.). We thank you for your patience as we endeavor to make improvements to our community. If you have questions regarding roadway/traffic issues, please call Engineering, at (925) 516-5420.
