While Berth 1 at Langdale terminal is closed for the replacement of one of the wingwalls, BC Ferries staff will strengthen the ramp to withstand earthquakes, assistant vice-president Jeanette McKay announced. "An engineering analysis of the structure and soils supporting the foundations revealed that the ramp could be at risk during even a moderate tremor," said McKay. Berth 1 has been closed since Jan. 17 to replace the wingwall - an outer section that holds the ferry in place when it docks - and had been scheduled to reopen March 17. With the seismic upgrade, the closure has been extended one month. Had the seismic upgrade been done separately, the berth would have been out of commission an extra two months. The ramp consists of six spans supported by three frames.
