BOULDER, Colo. - The University of Colorado at Boulder is adding some extra security measures for its graduation ceremony on Friday.
"We need your help to make sure it [commencement] stays a safe event," CU Police Public Information Officer Ryan Huff said in a video explaining the changes.
Attendees are being asked to bring as few items as possible. Visitors will only be allowed to bring soft-sided bags and containers no larger than 12-inches square (the size of a purse or small backpack) to Folsom Field.
Officials are asking that visitors consider using clear, plastic grocery-type bags to speed up the security screening process at entrance gates.
The security measures come after last month's Boston Marathon bombings when pressure-cooker bombs left in backpacks exploded in the crowd, killing three people and injuring 264.
People attending the CU commencement are also being asked to report all unattended or suspicious bags to police immediately.
Because of construction work on U.S. 36 leading into Boulder, visitors are being told to arrive early.
Gates open at 7 a.m. and guests should plan to be seated by 8:15 a.m. The ceremony will be held outdoors in the stadium regardless of the weather. In the event of heavy rain or snow an abbreviated ceremony will be held.
Parking lots and gray meters near the Coors Events Center are free for commencement parking.
The graduation speaker will be actress Julie Andrews.
