No word yet on whatever inspectors found that led to the closure of two lanes across the 1st Avenue South Bridge overnight, as reported here. We asked WSDOT for details; a spokesperson told us, “Our bridge engineers are on site today doing further assessments, after which we should be able to provide an update.” They also have opened the HOV lane to all traffic, in hopes that will reduce the potential for backups, though at “reduced speeds of 25 MPH over the bridge.” The bridge is a state-owned structure that was put to use as the major bridge across the Duwamish River during the two and a half years the West Seattle Bridge was out of service 2020-2022. It’s actually two bridges of different ages – the northbound side is older, built 70 years ago (lots of background in this story we published in 2020).
