Duquesne University officials, concerned about fallout from the G-20 summit, plan to cancel classes and close university offices from noon on Wednesday, Sept. 23, through Friday, Sept. 25.

Police won't be able to specify what roads will be closed around the university's campus until just days before the summit begins, and transportation restrictions that will restrict access to the campus are expected to be significant, according to an e-mail that university officials sent to students, professors and other staff members yesterday. As a result -- and on the advice of the city officials, regional planners and federal organizers with whom university officials have been speaking weekly -- the campus will close during the summit. Essential emergency personnel such as security guards are being asked to report for work, however.

Students will make up two of the days off by attending classes on Monday, Nov. 23 and Tuesday, Nov. 24, when they normally would be on vacation for the Thanksgiving holiday.

No other local universities have decided to cancel classes or change operations during the summit, although officials at several including Point Park University, Carlow University and Carnegie Mellon University are still considering possible changes. Officials at the Community College of Allegheny County could not be reached for comment.
