Similar to Boston's Big Dig project. Moving elevated highway that passes through downtown Seattle underground. |

*Also would have loved if we could have done something like The Highline in NYC with the old viaduct, but obviously that couldn't happen. Edited by Asalzwed 2013-09-11 4:46 PM |

Sensei Sin City | Subject: RE: Meet Bertha Those digging machines are so massive and specialized, they are built specifically for the job. They can't reuse them and cost millions upon millions just for themselves but can't logistically be reused. The two that dug the English Channel just dug a side tunnel to go down and they just buried/cemented them in. |
