The British Tunnelling Society (BTS) is encouraging our profession and the public to celebrate National Tunneling Day today, December 7. Their goal is to promote the industry (and its many professions) to students of all ages and the general public. The day is an annual event on the first Thursday of December, chosen due to its proximity to the Feast Day of St. Barbara, traditionally seen as the Patron Saint of Tunnellers in the UK.
I’m not much of a tunneling guy (yet!), but in honor of the day, let me share one massive tunneling project I was privileged to see up close. Check out my article and photos about my tour of the Bertha TBM site for the Alaskan Way Viaduct Replacement Project in Seattle, Washington.
