Seattle, WA: Tunneling Under the Alaskan Way Viaduct

Posted by Infra on Tuesday, May 10th, 2016

After nearly a week of tunneling under the Alaskan Way Viaduct, crews are steadily continuing Bertha’s underground drive towards downtown Seattle. This video gives you a behind-the-scenes glimpse into how the new tunnel is being built, showcasing the complex operations involved in this project. Massive concrete ring segments are transported to Bertha’s segment erector where they are lifted into place, allowing the machine to push forward while the excavated soil is transported along a network of conveyer belts and into a barge moored at Elliott Bay’s Pier 46.

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.

 

We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
