With the Skagit Valley Tulip Festival underway and a full deck of sports in Seattle, the roads will be packed. Here are some of the projects taking place this weekend that you will want to avoid or plan on adding time to your commute.
Everett: Northbound SR 529
The Washington State Department of Transportation (WSDOT) will close all northbound lanes of State Route 529 (SR 529) at the Steamboat Slough for WSDOT will provide a shuttle service to carry pedestrians, cyclists, and mobility device users around the closure.
Drivers will still be able to access Smith Island from northbound SR 529, but will only be able to leave the island on southbound SR 529 during the weekend closure between 9:30 p.m., Friday, through 5 a.m., Monday.
Drivers should prepare for added volumes on northbound Interstate 5 (I-5) through Everett all weekend.
Kirkland: Southbound I-405
WSDOT crews continue to make progress with the . This weekend will require the closure of 2 lanes southbound on Interstate 405 (I-405) between NE 124th Street and NE 85th Street. Crews will prepare the roadway for the southbound traffic switch to the new bridge in the coming weeks.
During the lane reductions, the Express Toll Lanes (ETLs) will be open to all drivers. Heads up: at a later date, the general-purpose lanes of southbound I-405 will shift to the new bridge during an overnight lane reduction, with the southbound ETLs shifting shortly after. Those dates have yet to be confirmed by WSDOT.
This project runs between 10:30 p.m., Friday through 6:30 a.m., Monday. Drivers headed to Seattle for games this weekend will need to add plenty of extra time to your commute.
Tacoma Narrows Bridge
Drivers traveling westbound on State Route 16 (SR 16) from Tacoma could see late night back ups. A section of highway will need 2 consecutive overnight closures to address expansion joint seals.
7 p.m. Friday, April 11 until 5 a.m. Saturday, April 12
- Two left lanes approaching the bridge, including the HOV lane, will close.
7 p.m. Saturday, April 12 until 5 a.m. Sunday, April 13
- Two right lanes approaching the bridge will close.
- Jackson Avenue on-ramp to westbound SR 16 will close.
- During the work, the HOV lane will remain open to all travelers.
These repairs are to the surface of the road at the east approach and does not include any bridge work itself.
Dupont: I-5 closure at Steilacoom-Dupont Road
If you happened to get stuck in this closure last weekend, this weekend is a repeat.
WSDOT crews need one final weekend to of the new overpass at I-5 and Steilacoom-Dupont Road. This massive undertaking involves placing steel beams over 50-yards in length and weighing over 200,000 pounds each over the busy freeway.
Most of the work was accomplished last weekend, but there’s still more to do. To safely guide these girders in place WSDOT needs to close the freeway in both directions at the work zone.
Overnight Friday, April 11 and Saturday, April 12, crews will reduce travel lanes in both directions of I-5 to a single lane. That up and over the Steilacoom-DuPont Road off- and on-ramps. Law enforcement will be in place to assist with traffic control at both the northbound and southbound I-5 ramps.
- I-5 lane closures start at 8 p.m.
- At 10 p.m. one lane will begin using the off- and on-ramps at Steilacoom-DuPont Road.
Lanes begin reopening at 6 a.m. Saturday, April 12 and Sunday, April 13
During these hours WSDOT recommends:
- Add at least one hour of extra travel time.
- Consider postponing or rescheduling discretionary trips.
- If possible, travel before or after the work.
