It has a length of  4,7858' (1481m) with a main span of 1,200' (366m). This is a David Steinman designed bridge. "During its construction, the contractor, McClintic Marshall, wanted to use a new heat treated suspension cable for the bridge, rather than traditional cold-drawn wire. David Steinman was reportedly against the use of this very new type of cable, but was convinced to use it by his company partner Holton Robinson. Unfortunately, this type of cable quickly proved to be unsafe for use as the wires started breaking after the stiffening trusses of the bridge had been erected on the bridge, proving that Steinman's hesitation was wise. Steinman condemned the wire and ordered it replaced with cold-drawn wire at the contractor's expense. The work required removing the newly installed stiffening truss, changing the cables, then re-erecting the new stiffening trusses." [HistoricBridges]

This is a deconstruction image because of the need to change the wire.

Bristol Ferry Lighthouse, Rhode Island

historic-structures
It started operation in 1855. "It is one of three early surviving lighthouses in the state of the type which features a keepers dwelling with an attached light tower...The most significant change to the lighthouse during its active period occurred in 1918 when the original wooden lantern at the top of the light tower was removed, the height of the tower was increased by six feet, and a new cast-iron lantern, gallery deck and balustrade were installed." It became obsolete in 1929 when the bridge was built because the bridge was a more visible navigation aid. It is now a private residence.

"The structure is similar in design to other lighthouses such as Rhode Island’s Nayatt Point Lighthouse as well as Sand Point Lighthouse in Escanaba, Michigan....A ferry, known as the Bristol Ferry, commenced operation between Bristol and Portsmouth around 1680 and afforded the most direct route between Newport and Boston by way of Providence. The ferry ceased operating in 1865, when a railroad line opened between Fall River and Newport, but the name Bristol Ferry remained associated with the narrow passage linking Narragansett Bay and Mount Hope Bay."
