Current Work (Updated 7/6/17)
PBOT’s contractor, McDonald Excavating, Inc., is placing UltraBlock retaining walls and importing fill to construct and “surcharge” the elevated roadway. Surcharge, also called pre-consolidation, is the process of placing extra fill material and allowing it to settle over a period of time in order to minimize the risk of future road settlement. Wall and surcharge construction will continue until October 2017, followed by an eight-month settlement period.
In spring 2018, utility relocation and environmental remediation work will take place under the Marquam Bridge to make way for the Bond Avenue connection to the existing River Parkway cul-de-sac. In May 2018, extra fill will be removed from the surcharge area and the connection to the Tilikum Crossing will be built. Major road construction will take place in summer 2018 and is scheduled for completion in late fall 2018. This page will be updated periodically as construction progresses.
