Critical Mass (Timber) Meetup Group
Timber bridges compose over a quarter of all bridges in North America, yet they compose only 7% of bridge expenditures on existing bridges mostly for maintenance. Meanwhile, new timber bridge construction is under 1% of all expenditures for greenfield bridge construction.
However, the world view on timber is changing with the advent of mass timber and tall timber structures. A carbon lens is redefining how we think about bridge infrastructure.
