Since the last twice-weekly update, the Highway 99 tunneling machine has passed the 8,000-foot mark of its 9,270-foot route. To be specific, as of today, it’s dug 8,132 feet and has 1,138 feet to go – about two more blocks, according to today’s WSDOT update. It’s currently near 6th/Wall and set to emerge at 6th/Thomas.
P.S. If you missed it earlier today, WSDOT has announced the Alaskan Way Viaduct’s next weekend maintenance (etc.) closure will be March 4-5.
