Until the late 19th century, there was not a single road leading in or out of Provincetown – the only land route connecting Provincetown to points beyond was along a thin stretch of beach along the shore to the north (locally called 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, a traveler using it still had to traverse several miles over a sand route, which, along with the backshore route, would occasionally be washed out by storms. This made Provincetown much like an island, in that it relied almost entirely upon its harbor for its communication, travel, and commerce needs.
