The I-405/SR 167 Executive Advisory Group has been advising WSDOT on the I-405 Corridor improvements since 1999. EAG members include state and local elected officials, and representatives from federal and regional transit agencies.
In 2010, EAG members signed an interest statement supporting the implementation of express toll lanes on I-405, which would connect with the express toll lanes on SR 167.

WSDOT has received funding to proceed with building express toll lanes between downtown Bellevue and Lynnwood (shown in green below) and to expand the southbound SR 167 express toll lanes to the Pierce County line. Additionally, express toll lanes between Renton and Bellevue and the I-405/SR 167 Interchange direct connector have recently received funding.

The I-405 Bellevue to Lynnwood Widening and Express Toll Lanes project, which began construction in 2012, will add strategic capacity in the north end of the I-405 corridor.
