Clemson became a sea of u-hauls for the annual move-in weekend. But tonight’s a time for festivities ahead of the new academic year. The official welcome back festival takes place this evening. And that’ll mean a part of College Avenue downtown, from Keith Street to highway 93, will be closed starting at 4:45 this afternoon and re-opening no later than 9 tonight. The parking deck will be accessible for parking. All vehicles should be removed from College Street before 4:30 this afternoon.
