US 101 - Simpson Bridge Pier Repair - Complete December 2012

In August 2010, WSDOT bridge engineers closed the US 101 Simpson Avenue Bridge after inspections revealed severe degradation to the pilings of the most easterly pier. 

The piers were reinforced to make the entire bridge more reliable for the traveling public.

Stabilization measures included:

  • Installing two additional pier supports at the NE and SE corners of the pier.
  • Strengthening the walls of the existing pier.
  • Transferring the remaining weight of the pier into the two new supports.
  • Removal of the temporary tie-back anchors and cables.
  • Removal/replacement of the pier fender protection system.
