The Washington State Department of Transportation (WSDOT) has permanently changed the speed limit on Interstate 5 between State Route 20 (milepost 230) and Cook Road (milepost 232) from 70 mph to 60 mph.
Part of an ongoing effort to make safety improvements in the area, the speed limit decrease is due to increased traffic flow. This 10-mile-per-hour decrease aligns with the speed zone to the south of this section of the interstate through Burlington and Mount Vernon.
