Timber bridges

We have worked on timber bridges for the last 20 years. We were involved in the joint Nordic Timber Bridge Project run by Nordic Wood, which ran from 1993 until 2001. During that period, we developed several of the first modern Timber bridges in Sweden.



3rd International Conference on Timber Bridges in Skellefteå, Sweden, 26-29 June, 2017

We have in cooperation with Luleå University of Technology the pleasure to invite you to a Conference on Timber Bridges which will take place in Skellefteå, in 26-29th of June 2017.

The successful conferences ICTB 2010 in Lillehammer, Norway, and ICTB2013 in Las Vegas, USA,  is now being followed up by a third conference  in Skellefteå, Sweden.


The conference will be a unique opportunity to network with an international community of experts on timber bridges, including highway, railway and pedestrian structures.


Over 650 new Timber bridges have been built in Sweden over the last 15 years. However, the Swedish Transport Administration's regulations for inspection of bridges are intended mainly for concrete and steel bridges. The materials used in wooden bridges are very different from those used in concrete and steel bridges. While it is corrosion that presents the greatest risk to concrete and steel bridges, it is moisture absorption by the wood, and the risk of attack by rot, that are the most important to monitor in the case of timber bridges. If the wood structures are kept dry - i.e. if the moisture content in the wood does not exceed 20 % over any longer periods - the structure can be expected to have a very long life. Regular inspections ensure that any problems are found at an early stage, thus enabling them to be dealt with in good time and proper maintenance work can be performed.


We arrange training in inspection of timber bridges. The training covers the special features of timber bridges, wood materials and the particular factors concerned in inspection of wooden structures. The courses are intended for those involved in such work in the Swedish Transport Administration, local authorities, consultants and other who need to know about timber bridges and their maintenance. See 'Training' tab.


We have published several reports on timber bridges, mostly in Swedish. The reports can be ordered from the publications tab.
