Project Info

I-5 - NE 117th St to SR 104 Pavement Repair - Complete November 2015

In summer 2014, crews replaced 277 concrete panels on I-5 between Northeast 117th Street near Northgate and SR 104 in Mountlake Terrace.

Panel replacement work was followed by grinding all the lanes to smooth bumps, remove wheel ruts and provide a better surface with increased traction.
The work extends the life of the road and improves driver safety. 

A new overhead electronic sign providing traveler information was also installed on southbound I-5 near the NE 145th Street interchange. 

How you benefit

Improves safety
Repairing the concrete reduces bumps and cracks, making for a safer, smoother ride. 
Grinding the concrete creates more friction for vehicle tires, improving traction and safety.

Economic incentive
Doing the repair work saves money in the long term and helps reduce the need for emergency repairs.

Partnerships & cooperation
WSDOT worked closely with the cities of Shoreline and Seattle during this project.

Age, traffic, and weather have contributed to cracking in the pavement.
Cracking on I-5 from 50 years of traffic and weather led to concrete in need of repair.
