I-405 Congestion Relief and Bus Rapid Transit Project
Project has received $485 million in state "Nickel Account" funding.  These projects relieve congestion on the I-405 corridor by adding capacity, improving safety, and investing in transit.  The project improves 22 miles of I-405 between Tukwila and Bothell.  Roadway improvements include two lanes added in each direction from downtown Bellevue south to SR 167 in Renton and related interchange improvements.  One lane will be added in each direction from the I-405/SR 167 Interchange south on SR 167 to 180th Street and west to I-5.  One lane will also be added south from SR 520 in Bellevue to SR 522 in Bothell and north from NE 70th Street to SR 522.  The project will include transit in-lane stations, HOV direct access ramps, park and ride lot expansion, and the purchase of both vanpools and buses.  In addition, bike trails and pedestrian connections will be built, and significant stream environmental enhancements will be made.  The project description above describes $2.72M RTID investment plus $500M from the state and $200M in federal funds.

Kent, Auburn

SR-167 Green Valley Corridor
Project has received $9.6 million in state "Nickel Account" funding." This project will improve congestion in the SR 167 corridor by addressing three critical transportation "chokepoints". First, the remaining sections of HOV lane will be completed from their current terminus in the vicinity of SR 18 in Auburn to the King/Pierce County line. This will match the HOV improvements which will be made in Pierce County. Second, one lane will be added in each direction from S. 180th Street (matching the I-405 Corridor improvements) to 84th Ave. S. The third project will add an auxiliary lane to SR 167 in each direction between SR 516 (Kent-Des Moines Rd.) and S. 277th Street.
