Press release:
Overnight lane closures will affect travelers entering and exiting the airport from State Route 518. The closures will be during the evening hours of Monday, October 31 between 11:30 p.m. and 4:30 a.m., plus the evening hours of Tuesday, November 1 between 11:30 p.m. and 9:00 a.m.

Monday night/Tuesday morning intermittent lane closures will reduce to one lane for both the approach to the SR 518 off-ramp to the Airport and the exit to SR99/154th. A single lane will be maintained at all times.

Tuesday night/Wednesday morning intermittent lane closures will reduce to one lane for both of the exits to SR 518. A single lane will be maintained at all times.

The closures are for upgrades to the roadway improvements for Sea-Tac Airport's Consolidated Rental Car Facility. The project is adding a lane to the SR 99 bridge southbound over SR 518 for convenient access to the new facility. A new ramp from SR 518 will take vehicles to the expanded bridge lane thus reducing the impact to regular traffic on SR 99/International Blvd. The new ramp and expanded bridge is expected to be open by early 2012. The Rental Car Facility is scheduled to open in April 2012.
