The 2009 I-405/SR 167 Executive Advisory Group selected Option 4, shown above, as a viable option for improving the I-405 corridor. This option adds express toll lanes between Renton and Lynnwood.
Express toll lanes on I-405 from downtown Bellevue to Lynnwood opened in 2015.
The Eastside Corridor, which stretches down I-405 and SR 167 to SR 512, is the only north-south highway alternative to I-5 in the Puget Sound region.
WSDOT has looked at a range of options for transportation improvement to address the projected increase in population and employment along this corridor. The I-405 Corridor Master Plan (pdf 174 kb) and the SR 167 Valley Freeway Plan acknowledge the importance of connecting I-405 and SR 167 to form a seamless corridor, and together they form the basis for the I-405/SR 167 Corridor vision.
The I-405/SR 167 Corridor Master Plan includes new highway lanes, improved interchanges, express toll lanes, expanded transit service including bus rapid transit (BRT) and expanded vanpool programs. Other features, such as the SR 167 Express Toll Lanes Pilot Project, the SR 167 extension in Pierce County and the I-405 express toll lanes will connect the entire corridor with a system better equipped to manage traffic demands in the future.
The first phase of I-405 express toll lanes opened in September 2015 in the 17-mile stretch between Northeast 6th Street in Bellevue and I-5 in Lynnwood.
Express toll lanes give drivers the choice to use the carpool lanes by paying a toll. Similar to the SR 167 HOT lanes, express toll lanes operate as an expressway within a highway while allowing toll-free trips for transit and vanpools.
Express toll lanes will better use the existing I-405 highway lanes and provide drivers with a more reliable trip. These lanes will use dynamic toll rates, which change based on real-time demand and congestion. The toll you see when you enter the lane is the price you will pay for the trip.
WSDOT is building express toll lanes because they:
