| Project Detail |
A regional project beginning in March 2024 will update 24 guardrails and attenuators along Interstates 5, 90 and 405, US 2 and State Routes 522 and 527 in King, Snohomish and Whatcom counties. The breakaway cable terminals, or guardrail protective end caps, face oncoming traffic and will be replaced with end caps designed to crumple and increase safety when hit. This project also will replace impact attenuators protecting concrete barriers at the James Street and Northeast 71st Street exits from southbound I-5 in Seattle, improving their ability to absorb energy in a crash and improving safety.
In September 2023, a second regional project improved and preserved a five-mile stretch of SR 18 near the Tiger Mountain State Forest. The project sealed cracks between Issaquah-Hobart Road Southeast and just south of Raging River. After pausing during the winter, the project resumed in April and made pavement repairs on 25 ramps at 12 interchanges along I-405 in Tukwila, Kirkland and Bothell, SR 509 in SeaTac, and SR 99/SR 599 in Tukwila and Edmonds.
A second phase of the regional repair project, scheduled to begin work in May 2024, will continue pavement repairs, grinding down damaged sections of pavement and repairing those sections with hot mix asphalt. The project also will retrofit curb ramps to meet Americans with Disabilities Act requirements and upgrade signals. Work is scheduled on I-5 ramps in SeaTac and Tukwila, I-405 ramps in Tukwila and Kirkland and on SR 18 from Issaquah-Hobart Road to just south of Deep Creek. |
