The ride on I-5 north of Seattle is on its way to getting a lot smoother, the Washington State Department of Transportation reported Friday.
The next step in rehabilitating and preserving the roadway between Northgate and Shoreline begins the night of Monday, Jan. 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 Northeast117th Street and SR 104 at the King-Snohomish county line, WSDOT said.
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, and 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 Northeast 155th Street to display travel times and driver information, pave the shoulders, and refresh the striping.
