Stone Arch Bridges
Friday, September 26 at 12:15 p.m.
Join us on a scenic tour of stone arch bridge construction from ancient to modern times. Learn why they work, how they work, and the terminology of their construction. Bob Tuthill will include images of stone arch bridges from around the world along with a selection of the masonry tools needed to shape the stone.
Bridges in the region include the Keystone Bridge near the Quabbin Reservoir, built under the supervision of Adolphus Porter in 1866 over the Middle Branch of the Swift River and the five stone bridges of Hillsborough, New Hampshire, the largest extant cluster of dry-laid stone arch bridges within the United States.
Bob Tuthill served on the University of Massachusetts faculty for 28 years teaching epidemiology to graduate students in the School of Public Health. Since his 1998 retirement, Bob, along with his wife Jackie, has visited all 17 towns of “Amherst” in the United States. His interest in this topic developed during a Five College Learning In Retirement course, “Bridges of the World.”
Join us with your lunch in hand. We will provide coffee, tea or cider for you as you listen to the presentations. The 30-minute program will begin promptly at 12:15 with seating and beverages ready just before noon. The lectures are free and everyone is welcome to attend.
