… Seattle Tunnel Partners (STP) started using barges to remove excavated soil from the SR 99 tunnel dig site this morning. The barges will take the excavated soil to Mats Mats, a quarry near Port Ludlow.
Prior to today, STP was using trucks to remove soil and dispose of it at facilities in the Puget Sound region. Moving forward, STP will use a combination of barges and trucks.
The labor issue that arose earlier in the tunnel drive has been resolved. Discussions between WSDOT and STP are ongoing. Details will be available upon the conclusion of those discussions.
By the way, a project-related closure of the Alaskan Way Viaduct is still looming, once the tunneling machine gets to the spot immediately beneath the existing structure, as first reported here back in April. We had asked Yerkan for an update and received this reply late Friday: “We still don’t have a date for when we will tunnel under the viaduct and thus close the structure to traffic for up to two weeks.”
