Welcome to the floor of the SR 99 tunnel launch pit. This photo gives you a sense of just how big this tunnel project is. Those concrete walls on either side of the tunnel launch pit are made up of interlocking concrete piles, 80 feet tall, that hold back the ground and water. See the worker looking up? Scroll toward the sky to see construction material being lowered into the pit. From this location, you can also see the walls of what will become one of the two tunnel operations buildings that will monitor everything from traffic to air quality inside the new tunnel.
This 360-degree photo is part of a virtual tour of the SR 99 Tunnel Project in Seattle. Learn more about the Alaskan Way Viaduct Replacement Program at www.alaskanwayviaduct.org or follow Bertha, the SR 99 tunneling machine, on Twitter @BerthaDigsSR99.
The United States is one of the most diverse countries on earth, jam packed full of amazing sights from St. Patrick's cathedral in New York to Mount Hollywood California.The Northeast region is where it all started. Thirteen British colonies fought the American Revolution from here and won their independence in the first successful colonial rebellion in history. Take a look at these rolling hills carpeted with foliage along the Hudson river here, north of New York City.The American south is known for its polite people and slow pace of life. Probably they move slowly because it's so hot. Southerners tend not to trust people from "up north" because they talk too fast. Here's a cemetery in Georgia where you can find graves of soldiers from the Civil War.The West Coast is sort of like another country that exists to make the east coast jealous. California is full of nothing but grizzly old miners digging for gold, a few gangster rappers, and then actors. That is to say, the West Coast functions as the imagination of the US, like a weird little brother who teases everybody then gets famous for making freaky art.The central part of the country is flat farmland all the way over to the Rocky Mountains. Up in the northwest corner you can find creative people in places like Portland and Seattle, along with awesome snowboarding and good beer. Text by Steve Smith.
