 Mostly light traffic right now, except in Auburn, where construction on Eastbound 18 has the left lane closed before Black Diamond Road, slowing down traffic from Auburn Way. In Renton, Northbound 405 is jammed up at the merge from 167. And in downtown Seattle, Northbound I-5 is busy from the West Seattle Bridge to Mercer Street. Drive time from Tacoma to Seattle, 40 minutes.
