St Austell Viaduct (MLN3 @ 286m 60ch - 286m 70ch). Also known as Trenance Viaduct. Prior to 1899
Brunel timber viaduct, 115 feet high and 720 feet long on 10 piers. It was built on a curve and crosses the road to Bodmin at an angle. The pier next to this road had to be built to an unusual triangular plan to fit this unusual configuration. The viaduct was replaced by a new stone viaduct in 1899. This sprung from the same point at the St Austell end before taking up an adjacent alignment. This meant that the northern half of the new viaduct was built first, the timber structure dismantled, and then the southern side completed. The viaduct is referred to as Trenance Viaduct on Ordnance Survey maps
