Tunnleing in Seattle

I received an email from the Washinton Department of Transportation regarding a talk on Seattle tunnels. The State is starting a big dig in Seattle to put a portion of Highway 99 below ground. This project will be a big change to the landscape of Seattle. It will not be the first big dig in Seattle.

There is of course the two tunnels that carry traffic on Interstate 90 through one of Seattle's drumlin hills. And all those north bound trains near Safeco Field, including coal trains pass though the heart of the city via tunnels. And then there are miles of less glamorous tunnels for water, sewage and other utilities. My underground work has been limited to a few ventures into exploration tunnels associated with ore mines.

Anyway what follows is WDOT anouncement:
