Crews working for Sound Transit will begin work to seismically retrofit the I-90 bridge columns near Lakeside Avenue to prepare for light rail construction and operation. Beginning as early as Aug. 24 and lasting for approximately seven months, this work will require long-term pedestrian and bicycle detours.
