The Central Business District is the site of multiple projects to repair and replace aging sewers, rail lines, bridge structures, streets, and other infrastructure. Projects with long-term benefits will cause short-term disruptions to residents, businesses and visitors. Environmental Services is coordinating with multiple agencies to schedule and complete construction, minimize disruptions, and help people get to where they are going. For information about other projects that will affect travel in and around the Central Business District, visit  

To avoid circling around construction to find parking, please use SmartPark garages.
