The Curran St onramp was also closed.
A 'Liberate the Lanes' rally was being held at Point Erin Park below the bridge, calling for a three-month trial of a cycle lane on the bridge.
After the protest, dozens of cyclists went past a police barricade and made their way across the bridge.
The northbound lanes opened after about two hours.
Police said they were "disappointed" by those who breached the cordons, and one person who initially breached the cordon was arrested and is being spoken to.
No injuries were reported.
Police said public safety was the "absolute priority".
Motorists have been urged to avoid the area and use alternative routes.
Cyclists celebrated the protest with selfies at the summit.
