| 摘要： | OR 38 is a mountainous two-lane route with large elevation changes that passes across Oregon's coastal range. Oregon's HfL project consisted of removing and replacing five bridges on an 11mi stretch of OR 38 between the towns of Drain and Elkton. All five bridges (Figure 1) were built in the late 1920s and early 1930s and were approaching the end of their useful life. Although all of the bridges identified for replacement had challenging site conditions, two (crossings 3 and 4) stood out for their exceptionally difficult topographic and environmental conditions. Crossings 3 and 4, located at mileposts (MP) 39.64 and 39.97, respectively, are situated at each end of the Elk Creek Tunnel in Elk Creek Tunnel State Park. |
