Lake Union Park business remain open as repair work begins this summer

Seattle Parks and Recreation(SPR) closed the Lake Union Park Bridge due to lateral movement of the bridge east abutment. SPR worked over the past two years to determine the overall cause of this movement, design corrective measures to remedy this and secure the necessary funding.

We recently awarded the construction contract to Jansen Construction. The project will remove and repair specific site elements and lighten soil loads by using geofoam to minimize future settlements. Jansen will begin to mobilize on site on Monday, July 10, 2017 and they anticipate work lasting four months. This repair work must be carried out during the drier months of the year.

Construction will include:

  • Replacing existing soil with lightweight geofoam under paved walkways along the western portion of the park “peninsula” west of MOHAI.
  • Modifying bridge abutment.
  • Repairing the boardwalk between the bridge and the bulkhead.
  • Reinstalling all paved walkways once the lightweight geofoam has been installed and the abutment modified.

Lake Union Park partner organizations will remain open and offer fun summer events and programs for all. Find out what’s happening at
