Site work, paving and new construction of a civil project in Renton, Washington. Completed plans call for the construction of a bridge / tunnel; for site work for a road / highway; for paving for a road / highway; bridge / tunnel; and bridge / tunnel.

As of June 2020, this project is in the final design work. Heavy construction is expected to begin at the end of June/beginning of July. Site prep and early construction has already begun and is ongoing. Geotechnical borings, high-visibility fencing installation and clearing and grubbing are approved activities under Phase 1 guidelines. An awarded general contractor joint venture team has been identified. The Renton to Bellevue project will add new capacity to create a two-lane express toll lane system between SR 167 in Renton and Northeast 6th Street in Bellevue. This project will connect a 40-mile system of express toll lanes that improves speeds and trip reliability for all travelers and supports the new I-405 Bus Rapid Transit system included in the Sound Transit 3 package.

Build a new Eastside Rail Corridor regional trail bridge over southbound I-405 at Wilburton. Express toll lanes Widen I-405 from north of SR 167 to just south of NE 6th Street (MP 2.5-13.7) to accommodate an additional lane both northbound and southbound. The additional lane will be paired with the existing northbound and southbound HOV lane to create two Express Toll Lanes (ETLs). Auxiliary lanes Construct a southbound I-405 auxiliary lane between NE 44th Street on-ramp and NE 30th Street off-ramp. Extend one of the southbound I-405 auxiliary lanes that currently starts at the I-90 on-ramp to end farther south at the 112th Avenue SE off-ramp. Bridges and structures Reconstruct local road overpasses at Cedar Avenue, Renton Avenue and Main Street to accommodate added I-405 lanes. Widen I-405 bridge structures over the Cedar River, NE Park Drive, Sunset Boulevard and SE 8th Street. Build a new northbound I-405 bridge structure over the Eastside Rail Corridor adjacent to the existing I-405 structure. Major interchange work Replace the 112th Avenue SE Interchange bridge structure over I-405. NE 44th Street Interchange: Replace the northbound and southbound I-405 bridge structures over May Creek. Replace the NE 44th Street bridge structure over I-405 and reconstruct the interchange. Construct new direct access ramps in the I-405 median. Realign and reconstruct Lake Washington Boulevard between NE 44th Street and SE 76th Street, and realign the northbound on-ramp to I-405 to connect to Lake Washington Boulevard. Local intersections will be roundabout controlled. Ramp reconfigurations Reconfigure the southbound I-405 to eastbound I-90 ramp from one lane to two lanes. Realign the northbound I-405 to eastbound I-90 ramp. Widen the existing northbound I-405 to SR 520 ramp from two lanes to three lanes. Environmental and other enhancements Construct two fish passage crossings under NE 44th Street and under I-405 for UNT 08.LW.0283 (formerly referred to as Gypsy Creek). Construct a fish passage crossing under I-405 for Stream 7.7A. Construct a fish passage crossing under I-405 for Stream 7.8. Construct new noise walls and relocate two existing noise walls. Construct stormwater management and water quality facilities. Other improvements will include pavement markings, permanent signing, illumination, intelligent transportation systems, barriers, and tolling gantries. Potential added scope Construct direct access ramps at 112th Avenue SE WSDOT - I-405/Renton to Bellevue - Corridor Widening and ETL
