 Northwest traffic from the High Performance Homes Traffic Center. A crash near Factoria on southbound 405. Blocking the carpool lane after Coal Creek Parkway, traffic can stop and go for about three miles around I-90. Coming in from the mountains, westbound Stevens Pass Highway is running slow for about four miles as you pass through Startup. A 30-minute delay getting to Sultan right now, and I expect that'll get worse here as the day goes on.
