Expect major back ups on southbound I-5 this weekend

The southbound I-5 express lanes will not open for the morning commute on Saturday or Sunday. The express lanes will open northbound at 1:30pm each day.

During the closures, WSDOT will work with the city of Seattle to clean up trash and debris along the interstate.

WSDOT crews will also use the closure to fill potholes, perform electrical work and complete various other maintenance tasks.

Southbound I-5 backups will start around 8am and continue through the evening hours on both Saturday and Sunday. Prepare for slowdowns to begin as far back as Snohomish County.
