The Maricopa County Department of Transportation serves as the streets department for Sun City West and Sun City. Additionally the agency and its staff administer hundreds of miles of other roadways in unincorporated areas of the county.
To see what their new and current projects are, residents may visit their projects website . There are several in Sun City West.
One new project, which is near to but outside the walls of Sun City West, involves the Northern Parkway. Many people in the northwest area use this as a thoroughfare into Phoenix and other areas.
That project will begin Jan. 2019 and is scheduled to run through July 2020. MCDOT has posted signs advising motorists to choose other routes during this time. A detailed description of the project can be found here.
