In mid-May, I took a trip into the Second Ave. Subway launch box as part of the MTA’s ceremonial launch of the tunnel boring machine. On Friday, MSNBC’s Rachel Maddow did the same, with a video camera in tow.
She ended her Geek Week special with a look at some impressive infrastructure projects. Although I’ve questioned whether or not Phase 1 of the SAS is a megaproject, the work going on underground is certainly impressive in scope, and Maddow brought it to light in an 11-minute segment, embedded below.
What I like most about Maddow’s coverage is the accompanying flickr photo set. By comparing her pictures with mine, we can see how far the 500-foot-long tunnel boring machine has dug out since it started work two weeks ago. For now, progress will be slow and steady, and the TBM should complete the two tunnels by next November.
