How will we address long-term solutions for I-405?
I-405 is one of the state's most congested corridors. Starting more than a decade ago, WSDOT worked with cities, counties, federal agencies, transit agencies and community groups to develop consensus on a long-term vision for the multimodal redevelopment of this highway.
This effort culminated in a three-year environmental impact statement (EIS) development process that outlines transit, roadway and environmental investments. The EIS, approved with the Record of Decision in October 2002, now serves as the corridor Master Plan. WSDOT continues to work with local communities and transit agencies to improve I-405.
What has the I-405 Corridor Program accomplished to date?

Since the master plan for I-405 improvements (PDF) was adopted, we have focused on funding groups of projects that directly address the worst congestion chokepoints first, coordinating all transportation modes into a working system. With funding from the 2003 Nickel and 2005 Transportation Partnership Account, the state has invested nearly $1.5 billion into the corridor.
Four Nickel-funded projects are complete (Kirkland Nickel Stage 1, South Bellevue Widening, Renton Stage 1 - Widening and the NE 116th Interchange and Street Improvement project). Three TPA-funded projects are complete (NE 10th Street Bridge-Stage 2, Renton Stage 2 - Widening, and NE 8th Street to SR 520 Improvement project), and one is under construction (NE 6th to I-5 Widening and Express Toll Lanes).
Several more projects received funding through the 2016 Connecting Washington package passed by the Legislature. The I-405/SR 167 Direct Connector is in the design stage and will begin construction later in 2016. The Renton to Bellevue Widening and Express Toll Lanes project is currently in the environmental review phase, with construction expected to begin in 2019.
The End Result: An Improved Multimodal System
The I-405 Master Plan is a balanced, multimodal plan to guide future transportation investments. Highlights include:
- Two new lanes in each direction
- Local arterial improvements
- 10 new transit centers
- Bus rapid transit (BRT) system
- 50 percent transit service increase
- Direct access ramps for transit and carpools
- 5,000 new Park and Ride spaces
- 1,700 new vanpools
- Bicycle and pedestrian improvements
- Managed lanes system
- Environmental enhancements, including stormwater and habitat improvements
What projects are currently unfunded?
WSDOT has identified several other projects throughout the corridor to advance the I-405 Master Plan, but these efforts remain unfunded.
Current funded I-405 improvement projects underway include:
