I-405/Northeast 85th Street Interchange and Inline BRT Station Project

WSDOT-I405-85thMap.png

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).

All information for this project, including closures and public meetings, can be found on the WSDOT project webpage 

Update as of 10:50 a.m. on March 15, 2024

NE 87th Street will be closed for a water vault and waterline installation. The closure will be along NE 87th St and 116th Ave NE between 114th Ave NE and NE 88th St (reference map below). 

Resident access, as well as access of vital services such as emergency vehicle responses, deliveries, garbage service, etc., will be maintained by the contractor during the closure.

Full closure of NE 87th Street was originally anticipated to begin Monday, March 18.  However, this start date has been delayed.  The City does not have an update from WSDOT/Graham on a new start date.  The work is still anticipated to wrap up in May.

The work includes: 
  • Installation of a new 24-inch watermain down the center of NE 87th Street
  • Installation of a new water vault at the corner of NE 87th St and 116th Ave NE

The map below shows both the closure and detour routes.  The closure is the solid orange line. The detour route is the dashed green line.

87th St Closure Map

To ensure that there’s enough space for two lanes of traffic along the detour, the contractor will place 24/7 temporary “no parking” signs for the duration of the closure along the detour:

  • South side of NE 88th St from 114th Ave NE to 116th Ave NE
  • East side of 114th Ave NE from NE 87th St to NE 88th St

This page will be updated as more information comes available. 

We appreciate your patience as WSDOT works towards creating a better and safer Northeast 85th Interchange for all travelers, regardless of how they travel. Learn more at https://bit.ly/85th-Interchange-BRT
