What They Found Digging Boston's First Subway in 1895—and Why the North Section Was Rerouted Forever

In the spring of eighteen ninety-five, construction crews began excavating a trench down the center of Tremont Street in Boston to build the first subway tunnel in North America. Using a cut and cover method, the work crews unexpectedly struck bone below a few feet of paving and fill when the trench reached the corner where Boylston Street meets the Common. The shovels had cut directly into the Central Burying Ground, a colonial cemetery established in seventeen fifty-six, because the required tunnel could not be built around it. This discovery was part of a larger effort to alleviate severe streetcar congestion on Tremont Street, where vehicles were bottlenecked during rush hours, and an elevated railway had been rejected by civic groups. The Massachusetts legislature had created the Boston Transit Commission in eighteen ninety-four, hiring chief engineer Howard A. Carson, who opted for a shallow tunnel to allow streetcars to descend on a manageable grade. The Central Burying Ground contained compacted remains from over a century of use, holding ordinary citizens, soldiers from the Revolutionary War, and notable figures such as portrait painter Gilbert Stuart. Due to earlier nineteenth-century landscaping that shifted headstones without moving the bodies, maps of the cemetery were already inaccurate. The sheer volume of recovered bones strained the city's recovery process, leading to an anonymous mass reburial for unidentifiable remains within the same grounds. As construction pushed north toward Scollay Square and Haymarket Square, engineers encountered filled ground that was once the tidal Mill Pond, featuring unstable soil, old wharf pilings, and unmapped colonial building foundations. These subsurface conditions forced the commission to alter the northern section's alignment block by block. Despite these obstacles, the first section opened in September eighteen ninety-seven, paving the way for future transit networks and leaving behind a physical record of the city's layered history.
