The need to reinforce a two-block section of the Alaskan Way Viaduct above the path of the upcoming tunnel means the viaduct will be closed from late Friday until early Monday morning, according to the state Department of Transportation.
It will be closed in both directions between the Battery Street Tunnel and the West Seattle Bridge from 11 p.m. Friday, April 6, to 5 a.m. Monday, April 9.
That could mean more than usual congestion in and near downtown Seattle during the closure.
“The weather is improving and shops and restaurants will be open for the holiday weekend,” Matt Preedy, WSDOT Alaskan Way Viaduct Replacement Program deputy administrator said in a news release. “Remember to plan ahead and allow a little extra time to get to your destination.”

From the WSDOT prepared statement:
Crews building the SR 99 tunnel will spend the weekend reinforcing both decks of a two-block section of the viaduct between South Washington and Columbia streets in Pioneer Square. There will be one additional weekend closure of the viaduct in mid-May to complete the scheduled work, which includes filling cracks and wrapping previously damaged sections of the structure in protective reinforcing fiber. Protecting this section of the viaduct is important because crews will drive the tunnel boring machine beneath it in late 2013.
