SEATTLE – This weekend’s Seafair fun combined with construction closures, including the State Route 99 Alaskan Way Viaduct, could mean traffic delays and downtown reroutes for Metro buses.

Closures on SR 99 start Saturday evening, when all northbound lanes close between the West Seattle Bridge and the Battery Street Tunnel for the Seafair Torchlight Run. SR 99 lanes north of the stadiums will reopen after the run, but the northbound lanes south of the stadiums will remain closed until Monday morning. Crews need the time to continue work on the second of two side-by-side bridges that will replace the south end of the viaduct.

“To connect the two bridges we need to fill a gap that’s about 2 feet wide and 700 feet long,” said Matt Preedy, Alaskan Way Viaduct Replacement Program deputy administrator for the Washington State Department of Transportation. “We need to keep traffic off of the northbound lanes because the vehicles cause too much vibration for the concrete to cure properly.”

But that’s not all. On Sunday evening, crews will close southbound SR 99 overnight starting just north of the Battery Street Tunnel to the West Seattle Bridge to continue reinforcing a two-block section of the viaduct above the route of the future SR 99 tunnel.

WSDOT recommends drivers to map out routes in advance, allow extra time and prepare for more congestion than usual.
