Шаблон:Infobox tunnel

Auburn Tunnel was a 19th-century canal tunnel built for the Schuylkill Canal near Auburn, Pennsylvania. It was the first transportation tunnel in the United States.[1]

The tunnel was deliberately added to the canal as a novelty, as the hill it was bored though could have easily been bypassed. It became a major attraction, with people traveling over Шаблон:Convert[2] upriver from Philadelphia to see it. It was periodically shortened, and in 1857 was daylighted to become an open-cut.[1]
