Tooth Rock Viaduct

From Oregon Hikers Field Guide

The Tooth Rock Viaduct was built in 1915. Designed by LW Metzger of the Oregon Highway Department, the viaduct is reinforced-concrete deck-girder span, similar in construction to viaducts at Crown Point and Multnomah Falls. The railings are spindle-and-cap railings similar to the Sheppard's Dell Bridge and the Moffett Creek Bridge. Long after the roadway was abandoned in 1937, the lack of maintenance took its toll and one of the spans collapsed under the weight of accumulated rock. Water penetration had severely damaged the railings, as well. The entire structure was rehabilitated in 1996, by the Oregon Department of Transportation as part of the Historic Columbia River Highway Trail.
