DESCRIPTION: The Lowell Covered Bridge is located adjacent to Jasper-Lowell Road in Lane County, Oregon. New drill shafts supporting the covered bridge were constructed in an effort to upgrade the original foundation system. However, the approaches to the covered bridge were not upgraded and are supported on wooden piles which were decaying. Reconstruction was completed for the approaches to the covered bridges using pre‑bored piles. The structure is limited to pedestrian access while the adjacent bridge on Jasper‑Lowell Road supports vehicle traffic.
SERVICES: Foundation Engineering provided exploratory drilling, engineering analysis, laboratory testing, and preparation of recommendations for the design and construction of new foundations.
