section. Three are located at Stoney Creek, Surprise Creek, and Christmas Creek. The other three are Bridge 21, the first steel bridge on the section, located between Tunnel 3 and Tunnel 4; Bridge 23, after Tunnel 9; and Bridge 29 between Stoney Creek Station and the Stoney Creek Bridge. The bridges have been renumbered since construction: for example, today's Bridge 21 was originally called Bridge 11. Stoney Creek Bridge Stoney Creek Bridge (originally bridge number 26, now bridge 30), in front of Stoney Creek Falls, is built on a radius curve and was designed by the government engineer John Gwynneth. The design is unique in Queensland, the curve being the only way to avoid tunnelling. By the end of 1887 the concrete foundations on which the wrought iron trestles (Phoenix columns) were erected were well underway. It is one of only two Queensland railway bridges constructed with wrought iron trestles, the other being Christmas Creek Bridge, further up the line. A visit to Cairns by the Governor of Queensland, Sir Henry Wylie Norman, in April 1890 was taken as an opportunity to inspect the construction works. A marquee, covering a banquet table and open to the waterfall, had been set up on the almost completed Stoney Creek Bridge with planks laid over the sleepers. There were no speeches due to the roar of the waterfall immediately behind the bridge. The bridge passed load testing on 30 June 1890. In the period of the early 1900s large quantities of rock in the vicinity of the bridge were removed, due to the risk of rock falls. Work was carried out in 1916 to strengthen riveted connections, and in 1922 timber longitudinals were substituted for the ballast flooring of the original bridge, to reduce corrosion problems. Stoney Creek Bridge is one of the most photographed bridges in Australia due to the spectacular beauty of its location. Historian John Kerr called it "the best-known structure on a line with the most spectacular scenery on the Queensland Railways". Trains would halt on the bridge and passengers could leave the train to walk along the bridge for a short period of time. In order to strengthen and improve the safety of the bridge, in the late 1990s new steel longitudinals were added under the bridge, the timber decking was replaced with steel grating and the walkways at the sides of the bridge were widened to improve
