Inspections of Sweden's longest suspension bridge, the approximately ten years old High Coast Suspension Bridge, have shown that the main bridge bearings have been seriously affected by wear. A monitoring program was therefore initiated in 2005 to measure actual vertical loads acting on the bearings as well as the tension in the first hangers of the bridge. This article describes the instrumentation and the calibration process. Interesting results from several months of monitoring are presented. Results show that the measured loads on the bearings due to permanent loads are in very good agreement with what was predicted during design. However, very large loads and large dynamic effects were registered from passing lorries.
