Last weekend, the Washington State Department of Transportation (WSDOT) closed southbound I-405 between Factoria and Renton for extensive projects, which are part of the overall I-405/Renton to Bellevue Widening and Express Toll Lanes Project.
Drivers should brace for a repeat, because more overnight closures are headed to the same stretch this week
On Wednesday, May 13, and Thursday, May 14, WSDOT will close all northbound lanes on I-405 between Coal Creek Parkway and North 30th Street to install overhead signs.
This is scheduled from 11:30 p.m. to 4 a.m., both nights.
The following ramps will be closed:
- Coal Creek Parkway on-ramp to northbound I-405
- Lake Washington Boulevard/Newcastle on-/off-ramps (Exit 9)
- Northeast 44th Street on-/off-ramps (Exit 7)
- Northbound I-405 off-ramp to North 30th Street (Exit 6)
A signed detour along Coal Creek Parkway will be in place.
Drivers are encouraged to consider traveling on I-5 during these overnight closures or plan on delays along alternate routes.
