Steel post-tensioning systems and stay cables are susceptible to corrosion. Carbon fiber systems are not. However, there was no experience on the long term behavior of such post-tensioned elements. Four external tendons (75 m long), stressed to a load of 2650 kN, were applied in a large balanced cantilever bridge and monitored for over 10 years. It appears that the stressing loads did not decrease and that the wires did not slip through the anchorages. The carbon fiber wires and the steel anchorages are in good condition.
