What is the Maricopa County DOT

The Maricopa County Department of Transportation (MCDOT) plans, designs, constructs, and maintains roadways within the county’s unincorporated areas.

What is now known as MCDOT began more than 150 years ago and was charged with maintaining a few roads in the newly formed Maricopa County. Currently MCDOT operates and maintains approximately 2500 miles of roadway, more than 80 bridges (16 of them more than 400 feet long) and more than 325 culverts, more than 115 signalized intersections and nearly 35,000 traffic signs.

MCDOT’s funding is primarily derived from Highway User Revenue Funds, and other federal and state sources. 

John Hauskins, P.E. is MCDOT’s Director. He is responsible for approximately 400 employees who operate out of the main headquarters on Durango Street in Phoenix, and three other maintenance facilities around the County.

Maricopa County has a population of approximately four million, and is the fourth most populous county in the US.  With more than nine-thousand square miles it is larger than seven different states.  The County is administered by a County Manager who reports to the five member Board of Supervisors elected by the public.
