 Northwest traffic from the High Performance Homes Traffic Center. A big crash in Des Moines on northbound I-5. Blocking three right lanes just before 516. Traffic is quickly backing up to 272nd. You're probably going to want to avoid the area if possible. And there's more trouble if you're heading north to downtown. Construction on northbound I-5 has the road down to two lanes at Boeing Field. And northbound I-5 is jammed up at the merge with I-90. Drive time from Tacoma to Seattle, 94 minutes.
