Pittsburgh Police were alerted to a report of 15 protesters on the Roberto Clemente Bridge around 8:30 a.m.  

When police arrived, they discovered protesters used bicycles to close the bridge to vehicles at the intersection of Sixth Avenue Fort Duquesne Boulevard. Two members of the group began to climb the archway attempting to hang a banner. Fire, EMS, and River Rescue responded to the scene for assistance.  Police closed the bridge to pedestrians and vehicles a short time later.  

Negotiators kept constant contact with the climbers. They were able to encourage them to rappel down just over 3-hours later. 

William Howison, 24 and Chelsea Lefever, 28 both of Pittsburgh were arrested without incident. Their charges are pending and the Roberto Clemente Bridge has since reopened.
