The site, a tunnel for moving cattle between the railroad and the nearby stockyards of the 19th century, was built in 1857. The cattle yards were closed in 1868[3] or "about 1871",[4] but the cattle trade continued; "until the 1920s, cows were unloaded here and driven down Massachusetts Avenue, through Harvard Square, and across the river to the Brighton Abattoir".[4]
Restoration (re-pointing) of the tunnel's brickwork was carried out during the 2007–08 replacement of the second-generation bridge dating from 1914.[2][5] The third-generation bridge opened for traffic in December 2008. The Cambridge City Council discussed creation of a vantage point for viewing the tunnel, ca. 2008, but no action was taken.
