Overnight closures planned on SR-518 through July
Overnight closures on SR-518 are planned through July, and the Washington State Department of Transportation is warning drivers to be aware and plan ahead.
Beginning Tuesday, May 28, crews working with the WSDOT will start replacing concrete panels along a three-quarter-mile stretch of SR-518 between I-5 and SR-99. Drivers can expect overnight, multi-lane closures during construction, although the eastbound and westbound ramps to the airport will remain open.
This area is heavily used by airport travelers and freight companies. In 2012, drivers made an average of 112,000 daily trips between the Airport Expressway and I-5. WSDOT maintenance crews say most drivers probably can’t feel it yet, but the cracks spreading across the roadway like spider webs are a sure sign the pavement is failing.
“The pavement is cracking, and we know that if we don’t do something soon, the roadway will deteriorate even more,” said WSDOT Project Engineer Janice Fahning.
During construction, crews may close all but one lane of SR 518 in each direction overnight Monday through Thursday. Additionally, all lanes of eastbound SR 518 will be closed overnight for up to four weekends. Drivers will follow a signed detour and should allow an extra 10-15 minutes to reach the airport or consider using an alternate route.
Crews from Atkinson Construction are scheduled to complete the work on SR 518 by Aug. 1.
Nightly road-closure information for SR 518 is available on the King County construction update website.
