All lanes on southbound I-405 in Renton have reopened after multiple cars were involved in a crash with a semi-truck.

Just one lane was open until the accident was cleared at approximately 6:30 a.m. Wednesday.

“If you plan on using SB I-405 to get to the airport this morning, you need to add 15 minutes at least to get through this crash scene in Renton,” KIRO traffic reporter Chris Sullivan said.

There was a backup of 2.5-3 miles, as of this reporting, causing delays of 15-20 minutes to morning commutes in the area.
