The East Harbor, which provided the most protected mooring place in Provincetown, had a inlet from Provincetown Harbor, and effectively blocked off access to Provincetown by land. Until the late 19th century, no road led to Provincetown – the only land route connecting the village to points back toward the mainland was along a thin stretch of beach along the shore to the north (known locally as the "backshore"). A wooden bridge was erected over the East Harbor in 1854, only to be destroyed by a winter storm and ice two years later. Although the bridge was replaced the following year, any traveler who crossed it still needed to traverse several miles over sand routes, which, together with the backshore route, was occasionally washed out by storms. This made Provincetown very much like an island. Its residents relied almost entirely upon its harbor for its communication, travel, and commerce needs.
