2 March 2024

All lanes of Interstate 5 (I-5) south remain blocked in Marysville, several hours after a significant crash early Saturday morning.

The incident, which the Washington State Patrol (WSP) called “serious” in a post on X, formerly known as Twitter, Saturday took place at 136 Street North about a mile north of Marysville.

Drivers are being re-routed to the Smokey Point Exit at State Route 531, which is Exit 206.

We are currently investigating a serious incident on SB I5 at 136th St N (MP 203) approximately one mile north of #Marysville. All lanes are blocked at this time. Please use alternate routes.
Updates will be provided as they are available.
