In 1985, Maricopa County voters approved a sales tax initiative
that authorized the Arizona Department of Transportation (ADOT) to embark on a
20-year program to build a comprehensive network of regional freeways in the
Phoenix metropolitan area. As of January 2005, the program was 78 percent
complete, and ADOT will most likely complete the remaining 22 percent by the
close of calendar year 2007, as planned. However, ADOT, the Maricopa County
Association of Governments, and the State Transportation Board (the three
organizations responsible for oversight of the regional freeway system) have an
opportunity to improve the program’s cost-efficiency and effectiveness.
Specifically, the oversight process should include a historical review of
projects’ progress when evaluating budgetary or timeline revisions. In
addition, program and project data currently residing in decentralized systems
should be consolidated.
