TIMBER BRIDGES - Ver.4 – September.2013
Introduction
SWECO hold a high competence on timber bridges and structures in general. Every
bridge shown in this brochure has been designed by Sweco and our collaborating
partners. The road bridges are calculated according to traffic loads given by the
Norwegian public roads administration (NPRA), and are built (or to be built) in
connection with public and private roads in Norway. These bridges have an expected
service life of 100 years.
Most of Swecos bridge engineers in Norway are situated in Lillehammer, Lysaker
and Bergen. Especially in Lillehammer many projects have been carried out in
cooperation with NPRA region east – which is the centre for timber bridges in
Norway. Timber bridge projects have also been carried out with other NPRA regions,
local authorities, estate developers, consultants and architects all across Norway.
The last two decade’s successful priority on timber bridges have resulted in
numerous bridges across the country. Timber bridges have been built in coastal
areas, in urban environments, in a military training ground, on woodland roads, over
railroads, highways and rivers etc. The technology developed in Norway has made it
possible to realise some of the most exiting projects worldwide. These projects have
all contributed in confirming timber as a competitive alternative to concrete and steel.
Sweco can also design simple, modern and reasonably priced timber deck bridges
for woodland-roads or low-traffic roads. Even though there are few timber bridges in
Norway of this type at the moment, they are expected to become more popular in the
near future.
This presentation is made by Sweco. Pictures and illustrations are produced by us or
our collaborating partners. Anyone may copy and use this presentation as a whole. If
anybody wants to use parts of this presentation in another context, please contact us!
