{"version":"2.6","id":"seatac-ongoing-construction-traffic-advisories","question":"What are the current construction traffic delays and detour routes around Sea-Tac airport that may affect transit times to and from the rental facility, including recommended buffer times?","answer":"Please check the latest updates on construction traffic delays and detour routes around Sea-Tac airport.","answer_detail":"To minimize the impact of construction traffic delays on your trip to and from the Sea-Tac Rental Car Facility, please be aware of the following ongoing construction projects and recommended buffer times. As of August 2024, there are several major construction projects affecting the roads leading to and from the airport. The most notable ones include the South 154th Street Improvement Project, which is expected to be completed by December 2024, and the Airport Access Feasibility Study, which will have a phased implementation schedule from 2025 to 2030. For the South 154th Street Improvement Project, you can expect significant delays during peak hours, especially between 7:00 AM and 9:00 AM, and again between 4:00 PM and 6:00 PM. We recommend adding a minimum of 30 minutes to your travel time to account for these delays. Additionally, please be aware that some roads may be closed or have reduced lanes due to construction, which may require you to take detours. To avoid getting stuck in traffic, we recommend checking the latest updates on traffic conditions and road closures before embarking on your journey. You can use online tools such as the Washington State Department of Transportation's traffic map or the King County Metro's trip planner to plan your route and get real-time traffic updates.","grokpedia_tier":false,"related_ids":["seatac-ongoing-construction-traffic-advisories"],"last_verified":"2026-08-09","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-ongoing-construction-traffic-advisories","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-ongoing-construction-traffic-advisories?format=md&lang=en"}
