The drilled shaft and driven pile test project will help engineers evaluate construction techniques for the replacement bridge support structures as well as the strength and stability of the soil, officials said.
“Information gained from this test will help us refine our assumptions and provide more certainty in our designs,” said Kris Strickler, CRC deputy project director. “This has the potential to reduce our cost of construction.”
Crews will drill three shafts and drive five piles at two on-land locations just west of the Interstate Bridge near the I-5/SR-14 interchange and the Hayden Island interchange in Oregon. The CRC said the locations are representative of in-water locations where actual supports will
be installed.
Several large cranes will be visible in the work areas just west of the interstate Bridge.
The project is scheduled to be complete this summer.
