Jan. 15, 2020: I-405 Renton to Bellevue Widening and ETL. The Project will add a dual express toll lane system each direction of Interstate 405 (I-405) from State Route (SR) 167 to NE 6th Street milepost (MP) 2.80 to 13.8, and an additional auxiliary lane southbound from MP 9.3 to 10.7. The project will include new bridge structures and widening of existing bridges. Bridge widening will occur on the southbound I-405 overpass at Cedar River (MP3.7), the northbound and southbound overpass at Sunset Boulevard (MP 4.5), the southbound overpass at SR 900 (MP 5.4), and the northbound overpass at SE 8th Street (MP 12.78). Bridge replacement will occur over I-405 at NE 44th Street (MP 7.4), 112th Avenue SE (MP 9.2), and Main St (MP 13.31); and under at May Creek. New bridge structures will be constructed at the southbound overpass at Coal Creek (MP 10.2), the northbound I-405 to eastbound I-90 ramp over the eastbound I-90 off ramp, Eastside Rail Corridor over southbound I-405, and the northbound overpass at the Wilburton crossing (MP 12.4). In addition to widening and interchange improvements, the project will address fish passage at select stream crossings. The project reconstructs a portion of the Newport Hills Park and Ride at 112th Ave SE. Additional improvements include construction of the Eastside Rail Corridor (ERC) regional trail from Ripley Lane to Coal Creek Parkway (MP 7.85 to 10.3) with a trail bridge crossing 405 at the former Wilburton rail bridge (MP 12.1) and four new noise walls.
