RECO worked closely with project architects and sculptors running through several design iterations during the progressive development of the exact panel finish required by the RTA and Fulton Hogan for the new Oak Flats interchange. The end result was two individual shell patterns and one Shell Harbour Council emblem itself to match with the vine pattern finish on the remainder of the TerraSet® panels for the four abutment walls, which have a total surface area of 3141m².
