Sound Transit is soliciting bids for contract CN 0154-25, the W205 Bi-Directional Load Test, with a closing date of March 13, 2026, at 2:00 PM PT. The project involves conducting a bi-directional load test at the Harbor Island site, located south of the West Seattle Bridge and east of the Duwamish River west waterway crossing. The primary objective of this work is to evaluate the performance and constructability of a permanent foundation system for a cable-stayed bridge that will support an aerial guideway. By verifying design assumptions and load responses, the test will allow the final design team to optimize foundation parameters and potentially adjust AASHTO LRFD resistance factors to ensure structural integrity and efficiency.
