UPDATE 3/25/11 9:30am: The Port of Seattle announced Friday morning (March 25th) that, “due to unforeseen conflicts, the overnight closures on the approach to and from Seattle-Tacoma International Airport have been POSTPONED and will NOT occur next week.”

The Port adds that the new schedule for the closure will be announced as soon as it is determined.

PREVIOUSLY:
Overnight closures on the approach to and from Sea-Tac Airport are scheduled for three days beginning Monday, March 28th, “to facilitate the installation of girders on the International Blvd. (SR99) bridge over State Route 518,” according to a Port of Seattle press release.

The Port says that road improvements will add a new lane to the bridge to facilitate the entrance to the new Rental Car Facility, located south of Highway 518, and scheduled to open in spring 2012.

The closures are scheduled to occur during the overnight hours between 11 p.m. and 4:30 a.m., in an effort to lessen the impact to commuters. Three closures will allow four separate girder sections to be placed on the evenings of Monday, Tuesday and Wednesday, March 28 – 30.

Vehicles will be detoured during each evening construction period. Detour routes will be marked and motorists are encouraged to use caution while traveling in the area.

Here are more details:

The first closure on Monday evening will detour vehicles west to the Des Moines Memorial Drive interchange and routed back along eastbound SR518 to reach the airport and SR99. The loop ramp to southbound SR99 will remain closed until later this year. Traffic will access southbound SR99 off of S. 154th Street.

The second night’s closure, Tuesday, will close both directions of SR518. Traffic will be detoured through the airport terminal drives.

Finally, Wednesday evening’s detours will close the airport exit to eastbound SR518. Traffic will be detoured to S. 170th St. and International Blvd.
