Old Scamander Bridge Demolition

Demolition of the unsafe Old Scamander Bridge, recycling 180 tonnes of steel and re-using the concrete deck, with a new pedestrian handrail system on the existing road bridge.

Project Overview

Demolition of the Old Scamander Bridge, which had been deemed unsafe for pedestrians, and construction of a new pedestrian handrail on the existing structure to separate pedestrians from traffic.

A detailed demolition plan kept the lead-coated steel structure from falling into the river. Piers were cut 3.5 m below mean water level with an electric wire saw, assisted by divers, and two BridgePro barges floated the three bridge sections to the southern shore.

180 tonnes of steel were removed and recycled. 220 tonnes of reinforced concrete deck were cut into 1 m sections and re-used as a capping layer over a redundant waste cell at the Scamander Transfer Station, along with 4,700 m³ of fill excavated from the approach roads.

BridgePro fabricated 68 galvanised and painted pedestrian panels and installed 68 stainless steel panels as part of the new handrail system. A professional liaison officer worked with the local community, who regarded the bridge as an icon.

Key figures: 180 t steel recycled, 220 t concrete deck re-used, 4,700 m³ fill excavated, 68 pedestrian panels fabricated.
