Lady Bird, the new TBM that will tunnel under the Potomac River for DC Water

The District of Columbia Water and Sewer Authority (DC Water) recently christened a new Tunnel Boring Machine ‘Lady Bird’ in honor of former first lady Claudia Alta ‘Lady Bird’ Taylor Johnson. The roughly 23-ft diameter TBM will tunnel a total of over 24,000 feet at a depth of 100 feet below the Potomac and Anacostia Rivers as part of a DC Water project aimed at reducing combined sewer outfalls. I first posted about this project, including a Google Map of the route a few years back. [Source: More at Tunnel Business Magazine. Image: Tunnel Business Magazine]
