In 2019, WSDOT contractor crews will grind and repave 2.2 miles of northbound I-5 between SR 104 in Mountlake Terrace and 164th Street Southwest in Lynnwood. They are also resurfacing the collector-distributor lanes on both directions of I-5 at SR 104 and 164th Street Southwest, along with most of the I-5 on- and off-ramps in this area.

In addition to the repaving work, the HOV bypass lane on the SR 104 on-ramp to northbound I-5 will be converted into a metered general purpose lane. This will help traffic flow more efficiently through the area during peak travel times.

Needs & benefits

About 163,000 vehicles travel this section of I-5 every day. The pavement is worn with ruts and cracks that can lead to potholes. The northbound lanes were last paved between 1996 and 2003. Asphalt is generally intended to last 15 years. New pavement is needed to keep the interstate in good condition for commuters and commercial drivers, while also reducing the risk of costly emergency repairs.

The southbound lanes in this area were repaved within the last five years and are not included in the project.
