In addition to the projects listed below that may impact your commute, you can find information on work being done to enhance our City on the Capital Improvement Projects Map and the Road Construction Map.

Paving on Main Street

Repaving is being completed on Main Street from Culver Drive to the San Diego Creek Channel  through mid-June, weather permitting.

Work will take place Monday through Friday between 9 a.m. and 3 p.m. Grinding and paving will begin at Culver Drive and continue north to completion.

Every effort will be made to complete this essential work quickly to minimize disruptions. Access to area residences and businesses will be maintained throughout the project.

Although one lane will remain open in each direction while work is underway, delays should be expected and motorists are encouraged to take alternate routes.
