## What to know

Please be advised that major infrastructure improvements are currently underway in the immediate vicinity of the SeaTac Rental Car Facility. Specifically, construction work is concentrated on International Blvd (SR 99) and the interchange with SR 518. These projects involve lane closures and adjusted traffic patterns, which can significantly increase travel times, particularly during peak morning and evening hours. To ensure you do not miss your flight or vehicle return appointment, we strongly recommend that travelers allow for an additional 30 minutes of transit time beyond what standard GPS applications typically estimate. We suggest utilizing real-time navigation tools such as Google Maps or Waze to monitor live traffic conditions and identify alternative routes. The Rental Car Facility remains fully accessible via the airport shuttle system, but the roads leading to the pickup points are subject to congestion. We appreciate your patience as these essential improvements are completed to enhance long-term transportation efficiency.
