Providence River
The Providence River is a tidal river in the U.S. state of Rhode Island. It flows approximately 8 miles (13 km). There are no dams along the river's length, although the Fox Point Hurricane Barrier is located south of downtown to protect the city of Providence from damaging tidal floods. The southern part of the river has been dredged at a cost of $65 million in federal and state funds to benefit nearby marinas and commercial shipping interests. The Dutch called the Providence River the "Nassau River". It was the northeastern limit of Dutch claims in  the colonial era, owing to Adriaen Block's exploration of Narragansett Bay, from 1614 until the Hartford Treaty of 1650. It can, therefore, be regarded as the original boundary between the English New England colonies and the Dutch colony of New Netherland. Course. The river is formed by the confluence of the Woonasquatucket and Moshassuck rivers in downtown Providence. One half mile downstream, it is joined from the east by the Seekonk River and continues south. The cities of Providence, Cranston, and Warwick lie to the west of the river, while the city of East Providence and the town of  Barrington lie to the east. At the narrows between Conimicut Point, in Warwick to the west and Nayatt Point in Barrington to the east, the Conimicut Shoal Lighthouse marks the entrance to the river from Narragansett Bay. Recreation. Since the late 1990s, the Providence River has been known for gondola rides, which can be enjoyed by tourists and locals daily in season. Providence's three gondolas and one sandolo are hand made in Italy and together "likely" comprise the largest gondola fleet in the United States. Crossings. Below is a list of all crossings over the Providence River. The list  starts at the headwaters and goes downstream.
