"When we are done, this will be the widest tunnel in the world—a double decker, four lane highway," he says, "that's pretty neat for us."
That tunnel is SR 99, the underground route that will eventually replace the Alaskan Way Viaduct, which connects West Seattle to Downtown. The project's overall budget is $394.8 million, a hefty investment from the city.
Westbrook has been recently working on building the walls for the giant tunnel boring machine's launch pit. According to Randy Erickson, who has been working on-site, the machine will be the largest and most complex in the world.
Erickson said there are rumors about plans to leave the tunnel boring machine in Seattle after the project's completion and build a museum around it. "Just something I heard," Erickson said, "it makes sense, because those drilling machines are such a hassle to move around and transport because of their size."
Drilling is expected to begin a little over a year from now in the Summer of 2013. For now, crews are currently working on a number of preparatory projects, including rerouting subterranean power lines, clearing the waterfront of obstructions like small trees, clearing old buildings and structures from the 1920s and 30s, and preparing space for the arrival of the boring machines.
In the meantime, construction crews are rerouting traffic on East Marginal Way South, due to reduced lanes, and ask that drivers passing through be conscious of the tight squeeze and mindful of cyclists.
"It gets tricky when there are games at the stadium," said Molly Chen, a cyclist who frequents the route. "You just have to be extra vigilant cycling through here with the construction because there isn't as much space for the inflow of sports traffic."
While the traffic doesn't bother Chen too much, she wasn't as excited about the prospect of a possible tunnel-boring museum.
"Why you would want to build a museum around a giant digging machine, I have no idea," Chen said. "I feel like that would just be really ugly and unnecessary."
