Martins Ferry Bridge Rehabilitation - Weitchpec, CA
Client: Mercer-Fraser
Funding Source: Caltrans
Project Location: Klamath River Bridge (Martins Ferry) - State Highway Route 169
Mercer-Fraser hired Pacific Affiliates as a construction engineering consultant to monitor bridge movement via routine surveys and inspection during the seismic retrofit and rehabilitation of the Martins Ferry Bridge. The bridge is located on State Highway Route 169 passing over the Klamath River. The temporary bridge ensured that traffic was able to continue travel over the Klamath River during the construction phases of the newly rehabilitated bridge. This project was a critical undertaking as the east hill side of the bridge was slipping into the river and taking the bridge foundations with it, potentially resulting in bridge collapse.
Tasks performed:
- Birdge Monitoring before, during and after construction
