12:30 p.m. UPDATE: Good news! No need for Saturday night northbound I-5 total closure in DuPont. We completed work last night. Thanks for everyone's help as we reach a key stage in this project to build a new Steilacoom-DuPont Road overpass.

We've got a fresh, locally grown and region-specific Paint Map on the menu to emphasize some closures you should know about if you're traveling in, around, or to Seattle this weekend.
Our first course is a closure of SB SR 167 in Kent. This will be closed from 11:59 p.m. Friday to 4 a.m. Monday between SR 516/Willis Street and South 277th Street (mileposts 18-19). The detour directs travelers to West Valley Highway, but expect delays because West Valley Highway doesn't have as much capacity as the highway. Consider alternate routes like I-5 if you can. During the closure, we'll replace expansion bridge joints on and repave the Green River Bridge.
Next up is a full closure of EB SR 18 in Auburn. This will be closed from 9 p.m. Friday until 5 a.m. Monday between C Street Southwest and Auburn Way South. The EB SR 18 on-ramp from C Street Southwest and off-ramp to Auburn Way South will also close. Law enforcement officers will help direct traffic through the detour. Expect delays. We'll use the closure to grind pavement, perform full-depth pavement repairs and install traffic loops and temporary lane striping, creating a smoother ride and preserving the highway for years to come.
The main course is one you're likely familiar with by now: NB I-5 over the Ship Canal Bridge is reduced two lanes until Aug. 15. Express lanes remain open northbound 24/7. Expect delays. Start planning ahead for your weekend travels NOW and consider using alternative forms of transportation - like a bike, bus or light rail.
For dessert, we have overnight closures of NB I-5 in DuPont on Friday and Saturday. These closures will be 10 p.m. to 6 a.m. each night, and traffic will be directed up and over the Steilacoom-DuPont Road exit and on-ramp. Expect heavy congestion.
As always, download our app, check our travel map for real-time info, MAKE A PLAN and enjoy your weekend.
