Next year, the world's largest-diameter tunneling machine will begin boring the SR 99 tunnel to replace the Alaskan Way Viaduct. But please don't call her boring. Instead, call her Bertha. The WSDOT held a public contest to name the machine and somehow, they ended up naming her after former Seattle Mayor Bertha Knight Landes. They even gave Bertha a Twitter account. Given how iffy the ground is underneath downtown Seattle, we really hope she doesn't tweet while drilling. [@BerthaDigsSR99]
