Alaskan Way Viaduct Replacement to Resume

The Alaskan Way Viaduct replacement is a transportation megaproject in the City of Seattle, Washington.  The project consists of replacing an overcrowded and unsightly elevated highway along Seattle's waterfront with an underground tunnel.  The 57-foot diameter tunneling machine, termed Bertha, is scheduled to resume tunneling operations on December 23, 2015, after approximately two years of repair operations. 

The Indian capital can be now considered, on a global scale, as one the cities where the largest tunneling project has ever been undertaken. According to the Delhi Metro officials this is not an understatement considering the 19 Tunnel Boring Machines (TBM) that are simultaneously working underneath the city. Phase III of the metro expansion is expected to complete by the end of the year.
