Greater Boston has partnered with the Boston Globe to bring you a weekly feature called "From the Archives." Each Wednesday on Greater Boston, we will show one to two photos from the newspaper's archives . This weekly feature offers a glimpse into Boston's past.
 
This week, we look at … a key transportation artery.
In 1934, the Sumner Tunnel opened beneath the harbor, connecting East Boston and eventually Logan International Airport to the rest of the city. In this photo, automobiles enter the Sumner on April 24, 1958. Almost exactly a year after this picture was taken, on April 30, 1959, more than 1,000 people attended a groundbreaking ceremony for construction of a second tunnel to run parallel to the then–25-year-old Sumner. The Lieutenant William F. Callahan Tunnel opened on Nov. 11, 1961. And finally the third harbor tunnel, the Ted Williams Tunnel, opened in 2003, a substantial outcome of Boston’s Big Dig.
