Project overview
WSDOT, Sound Transit, and design-build contractor Graham Contracting, Ltd. are working to reconstruct and improve the I-405/Northeast 85th Street interchange. This project design supports Sound Transit's Stride Bus Rapid Transit (BRT), improves transit connections on Northeast 85th Street, and provides direct access to the I-405 Express Toll Lanes (ETLs).
With the City of Kirkland’s support, WSDOT and Sound Transit chose Northeast 85th Street for this project because it is a main connection between Downtown Kirkland, Redmond, and I-405. Working together, WSDOT, the City of Kirkland, and Sound Transit developed this project to improve accessibility for transit riders along the I-405 corridor and throughout the region and improve mobility and people who walk, bike, or roll.
The current interchange has two levels: the bottom level for local traffic on Northeast 85th Street and the top level for freeway traffic on I-405.
Project improvements along the lower level include local road improvements along Northeast 85th Street and its intersection with 114th Avenue Northeast/Kirkland Way.
The newly constructed middle level of the interchange is a multimodal hub. The hub will improve access and save time for transit riders, carpoolers, ETL users, and people who walk, bike, or roll. Transit riders will benefit from a new BRT station in the median of the northbound and southbound lanes, with connections to local bus stops. Pedestrians and cyclists will have wider sidewalks and better connections to BRT and the regional transit network. Carpoolers and ETL users will have direct-access ramps to the ETL system on I-405.
The project will also remove fish barriers, add noise walls, and add new stormwater facilities.
Once finished, this project will offer safer, more reliable transportation options for Kirkland residents, neighbors, and commuters – no matter how they get around.
What to expect
Multiple directional closures along I-405/SR 167 corridor, July 11-14
Travelers should plan for closures on southbound Interstate 405 in Kirkland, northbound I-405 in Renton, and southbound State Route 167 in Kent from Friday, July 11 to Monday, July 14. Crews will be completing complex construction activities for three projects along the I-405/SR 167 corridor:
- I-405/Northeast 85th Street Interchange and Inline BRT Station Project
- I-405/Renton to Bellevue Widening and Express Toll Lanes Project
- SR 167 Corridor Improvements Project
What to expect
Travelers should expect on Saturday and Sunday, July 12-13:
- Heavy traffic on the Eastside on northbound and southbound I-405
- Heavy traffic on southbound SR 167 in Kent
Detour routes cannot accommodate normal I-405 and SR 167 traffic volume, so travelers are advised to “know before you go," travel during off-peak hours or, if possible, delay discretionary travel to help minimize backups.
