Smartphone technology is being used in Sweden to provide better knowledge about the performance of timber bridges.

Sensors have been mounted on Alvsbacka Bridge, a 130m pedestrian and cycle bridge built by timber structure manufacturer Martinson, as part of a research project by Wood Technology with Luleå University of Technology.

The sensors will supply data on wind gusts, foot traffic and the effects of seasonal changes over time periods up to 10 years.

“The results will allow providers [timber bridge manufacturers] to ensure quality in a whole new way and make sure that future timber bridges will be even better,” said Olle Hagman, of Luleå University.
