Construction project to impact airport users through early 2025

Traffic detours and other measures start in early July

UPS has kicked off the final stage of its multi-year project for its Gateway facility at King County International Airport-Boeing Field. This final phase will include the removal of the 7300 Building to create additional employee parking, as well as realign the airport terminal loop road. This will help reduce driver confusion when exiting the terminal.

Work has started on the inside of the 7300 Building. Exterior work, including the road realignment, will begin in early July and is scheduled to be complete by early 2025. During this phase of the work, Perimeter Road between South Othello Street and the UPS site entrance will be closed. Below is a map of the areas impacted by this work.

Construction and mobilization will start in July, with demolition of the 7300 Building in the first week of the month. The South Othello Road and Perimeter Road closure will start the first week of August. During the road closure, all outbound terminal traffic must use the north exit to exit from Perimeter Road to access Airport Way South. There will be no access to Airport Way from Othello Road or directly from the Terminal Access Road or Terminal Parking. A map identifying the northbound exit and detour route is below.

As part of our commitment to ensuring the safety and efficiency of our community, we would like to inform you about the rules and regulations regarding the upcoming traffic impact due to ongoing construction activities.

  • Speed Limits: Please adhere to all posted speed limits within the construction zone. Reduced speed limits are implemented for the safety of both workers and motorists
  • Lane Closures: Temporary lane closures may be in effect to accommodate construction activities. Please follow signage and instructions to safely navigate through the area
  • Alternate Routes: Consider using alternate routes, if possible, to avoid congestion near the construction site. Plan your travel ahead of time to minimize delays
  • Pedestrian Safety: Exercise caution when navigating sidewalks near construction zones
  • Parking Restrictions: Temporary parking restrictions may be in place near the construction site to facilitate work operations. Please respect these restrictions to ensure smooth traffic flow and avoid potential fines or towing

We appreciate your cooperation and understanding during this project. These measures are being implemented to enhance the safety and functionality of our community's infrastructure.
