As 2-week closure looms, state answers concerns about safety of Seattle’s viaduct
As a two-week closure of Seattle’s Alaskan Way Viaduct approaches, drivers are urged to plan alternate routes to help ease what are expected to be major traffic impacts. Meanwhile, state officials are trying to quell concerns that the closure could last longer than expected. Starting Friday, April 29, State Route 99 will be closed from the south end of the Battery Street Tunnel to Spokane Street as Seattle’s tunnel boring machine, Bertha, begin drilling beneath the structure.
