Several exciting building and renovation projects are occurring on our campus. Project teams are coordinating their construction plans in order to expedite each project while keeping the safety of faculty, staff, students, construction workers and the public a top priority.
Put Safety First – Please be mindful of all construction-related signage as well as fenced or barricaded areas. These are placed for your safety and to keep you clear of construction activity.
Many of these projects impact the nearby streets, roadways and parking areas. This page is intended to inform employees, students and visitors about changes in vehicle and pedestrian traffic patterns near the construction areas. For questions about a specific project, please view the project site or call our U-M Construction Management Information line at 734-764-9289.
