TIMBER BRIDGES--A REBIRTH (SECOND IN A SERIES OF TWO ARTICLES ON TIMBER BRIDGES)

Following a brief discussion of the Timber Bridge Initiative, this article discusses two bridges which were constructed in Wisconsin under the demonstration bridge segment of the Timber Bridge Initiative. These two bridges, the Teal River Bridge in Sawyer County and the Richland Center Bridge in Richland County, demonstrate that red pine is a feasible structural material for glulam timber bridges. The structural properties of red pine glulam are 10% to 20% less than those of southern pine glulam, but, with known properties, engineers can design bridges that meet today's standards for highway loads.
