CDOT is headed by the Commissioner of Transportation, an appointee and cabinet member of the Mayor of Chicago. The second in command at CDOT is the First Deputy Commissioner, who serves as a liaison between the Commissioner's office and the various operational sections. Managing Deputy Commissioners may also be placed by the Commissioner for assistance in policy and operational oversight.

CDOT is organized into several Divisions each headed by a Deputy Commissioner, including the Divisions of Administration, Project Development, Engineering, In-House Construction, Electrical Operations, Sign Management, Traffic Safety, and Infrastructure Management.

History

CDOT was established by order of the Chicago City Council on 11 December 1991 when Mayor Richard M. Daley restructured the Chicago Department of Public Works into the new Chicago Department of Transportation. The restructuring took effect on 1 January 1992. John N. LaPlante, who was appointed as Acting Commissioner of Public Works in September 1991, continued as the first Acting Commissioner of CDOT.

In 2011, the Chicago Department of Environment was disbanded and absorbed by other city departments including General Services, Public Health, Family and Support Services, and Water Management. The Department of Transportation took over Environment's Clean Vehicles Initiative.

Department of Public Works

Prior to the 1991 reorganization, the responsibilities of the Department of Transportation (and several other current city departments) belonged to the Chicago Department of Public Works. The Department of Public Works was first recognized as a branch of the city administration in 1861, at which point it consolidated the services of water, sewerage, parks, streets, river and harbor, and public buildings. Initially, the department was headed by an elective board of public works. In 1867, the board became appointive, and in 1876, the board was completely abolished in favor of a single commissioner. Mayor Heath served as the first temporary head of the department until a commissioner was provided in May, 1879. The office of deputy-commissioner was created in 1892. At the time of creation (but no longer the case), the position was at the appointment of the mayor, which created a confusing line of responsibility for the heads of the department.

After the abolishment of the three-man board in 1876, the department was composed of the bureaus of water, sewerage, streets, special assessment, engineering, and maps.

List of commissioners

Since the Department's inception in 1991, the position of Commissioner of Transportation has been filled fourteen times by thirteen individuals, including five official "Acting Commissioners".
