SEATTLE -- On day seven of the Alaskan Way viaduct closure, Bertha passed the halfway point. The tunnel boring machine is 50.6 percent done drilling under the viaduct, having dug 195 of the approximately 385 feet it needs to drill before the viaduct can reopen.

As of Thursday evening, Bertha is nearing the intersection of Yesler and Alaskan Ways.

Drivers saw some of the worst traffic this morning since the viaduct closed, but afternoon commuters didn't see as much gridlock.

WSDOT said evening commuters saw travel times up by about 15 minutes for a Thursday afternoon. Also, downtown Seattle protests blocked streets at 5th Avenue and James Street and 7th Aveneue and Stewart Street, slowing evening travel times.
