Public Works is responsible for the engineering, construction and maintenance of the County's numerous roads, bridges and canals, along with the traffic signals and signs that support them. Not only does Public Works oversee and administer the collection of tolls on both the Rickenbacker and Venetian Causeways, but the department is committed to beautifying and maintaining landscapes along the public rights-of-way of Miami-Dade County.

The department also enables the creation of Special Taxing Districts to provide special services or make specific infrastructure improvements to neighborhoods that otherwise could not be provided.

Public Works also implements local and state mosquito control programs to help minimize the threat of disease.

The Miami-Dade County Public Works Department consists of 17 divisions staffed by almost 900 employees all dedicated to our mission of serving and working for the citizens of Miami-Dade County. In addition to being the administrative center for the department's operations, the Office of the Director  also serves as a clearing house for citizen questions and concerns about public works.
