Concrete repairs on I-5 now set to begin next week

Due to schedule conflicts with neighboring projects, the Washington State Department of Transportation said its plan to replace concrete panels at various locations on I-5 between Tukwila and Shoreline — the result of heat damage in summer 2021 — was delayed one week. Work will now start on Monday, Feb. 7.

Nightly lane closures on I-5 will be used to complete the work. Lanes will begin closing as early as 8 p.m. in some areas, potentially reducing one direction of the highway to a single lane by midnight. All lanes will reopen early the next morning.

Crews will sawcut and excavate the existing damaged pavement, then pour new concrete panels. Many of the 46 concrete panels due to be replaced are located in the Shoreline area. These panels were damaged last year when extreme heat caused the pavement to expand and crack. WSDOT maintenance teams patched these areas, but those repairs were meant to be temporary.

The best way to track closure locations and times is by using the WSDOT real-time travel map or downloading the WSDOT mobile app. This work is weather-dependent and will likely be rescheduled if there is rain in the forecast
