About

The project involves the construction of a new 11 span, 349-metre-long, 16-metre-wide bridge to the north of the existing Kings Highway bridge over the Clyde River and upgrade of approximately 1.4km of the Kings Highway approaches (including partial realignment) to the new bridge on both sides of the river, including upgrades to intersecting roads. The new 11 span Super T bridge will accommodate 2 traffic lanes, with a 2-metre-wide shared path. The new bridge sits some 7-metres above the Clyde River and includes 2 piers over land and 8 piers over water, all with bored piles cast insitu.

Other key works include demolition of the existing bridge, new retaining walls, earthworks (including CIC treatments), pavements, stormwater drainage, footpaths/ pedestrian access, public utility adjustments/ protection, street lighting, property adjustments and landscaping.
