Bridge over the Harbour, known for the iconic counter weights of the lifting section which resemble the shape of movie character Shrek, hence its popular name with the locals. Its formal name Pero's Bridge is a reference to Pero Jones, a Caribbean slave who arrived in Bristol through the harbour channel below the bridge in the 18th. Although the bridges hydraulic mechanism allows it to open and close swiftly, it only does so rarely because the ferry was designed explicitly to pass under the bridge without it needing to be lifted.
