Concrete grinding begins next week on I-5 between Shoreline and Northgate

From WSDOT 

The ride on I-5 north of Seattle is on its way to getting a lot smoother.

The next step in rehabilitating and preserving the roadway between Northgate and Shoreline begins the night of Monday, January 26. That’s when contractors working for WSDOT start the process of grinding all the lanes. The grinding work is the second half of the pavement repair project between NE 117th Street and SR 104 (NE 205th) at the King-Snohomish county line.

This past winter, the contractors replaced nearly 300 broken concrete panels on I-5. However, the new panels are not quite flush with the interstate resulting in a noticeable bump when driving over them. Grinding all the lanes will get rid of this bumpiness. It will also remove shallow cracks, ruts and create a smoother driving surface with better traction.

The project will also add a new overhead electronic sign just south of NE 155th Street to display travel times and driver information, pave the shoulders, and refresh the striping.
