Union Slough Bridge
Posted June 16, 2012, by Daryl Mills (greimatter [at] comcast [dot] net)

Originally designed for Northbound and Southbound traffic on US 99. Prior to this, US 99 was routed to the east to avoid the water crossings. This alignment lines up with a northerly swing span leading into Marysville, which is now replaced and scheduled for demolition.
