Senator Claiborne Pell in , but most people still refer to it by its original name. The bridge spans 11, feet, making it one of the longest suspension bridges in the world. And since about 27, vehicles pass over it every day, it's safe to say it's essential to our state. On any given day, you'll probably notice a photographer or two in the area.

RI 5 Replaced by new bridge 18, Rhode Island Span length feet Structurally deficient 13, Through truss 15, Total length over feet Truss 34, Although the original design specified that depths of 90 to feet would be adequate, additional tests conducted by the state found that depths of to feet were necessary to support the concrete bridge and the four lanes of traffic that would be carried on it.
CFF also encountered problems with the concrete foundation work and the Jamestown approach. With construction only about 25 percent complete, CFF went to State Superior Court on February 18, to prevent the state from requiring it to install the deeper piles under breach of contract, contending that the new piling system required a new construction contract.
The two parties agreed formally to terminate the contract on March 21, ; the state subsequently countersued CFF for contractor incompetence.
For nearly a year and a half, nearly all construction activities ceased on the span as the RIDOT sought new bids to complete the bridge. A new joint venture of the Guy F. Construction resumed on the new span that September. The new Jamestown-Verrazano Bridge opened to traffic on October 8, To the west, the bridge connected to a newly expanded RI Expressway, which was widened from a two-lane undivided "super 2" controlled-access road to a four-lane, median-separated freeway one year earlier.
To the left is the old Jamestown Bridge, which was closed to vehicular traffic in and torn down in Photo by Jim K. An alternative plan offered by the Sierra Club called for the state to maintain the old bridge in its entirety as a multi-use trail for use by pedestrians and cyclists.
Both plans were to be serviced by a parking area in North Kingstown with dedicated ramps to and from the RI Expressway. However, the RIDOT soon stopped maintenance on the old bridge, and its state of disrepair accelerated. Attempts to rehabilitate the old bridge ran into state and Federal funding roadblocks during the 's, but this race against the clock did not turn out in the bridge's favor.
Subsequent inspections found that the bridge had deteriorated beyond repair, and the decaying bridge was considered a hazard to navigation to the U. Coast Guard, which threatened to fine the state.
Short of funding, the RIDOT tried an innovative solution: it offered Hollywood studios the chance to blow up the old bridge if they paid the demolition costs. It also tried to give the bridge away to anyone who wanted it, but its advanced state of deterioration likely deterred buyers.
The Jamestown Bridge , usually referred to as the Old Jamestown Bridge to avoid confusion with its replacement, the new Jamestown Verrazzano Bridge , was a cantilever truss bridge that connected Conanicut Island to mainland North Kingstown , Rhode Island , spanning the West passage of Narragansett Bay. The bridge first opened to traffic in , replacing ferry service as the primary connection for the town of Jamestown , situated on Conanicut Island.
With a total length of 6, feet 2, m , the Jamestown Bridge was the third longest in Rhode Island at the time of its destruction, ranking behind its replacement, the adjacent 7,foot 2, m Jamestown-Verrazano Bridge, and the 11,foot 3, m Claiborne Pell Newport Bridge connecting Conanicut Island to Aquidneck Island and Newport. The Jamestown Bridge was closed to vehicular traffic on October 8, , and its main span was destroyed through a controlled demolition on April 18, The bridge consisted of 69 spans with a large continuous cantilever Warren truss centerpiece.
The bridge was long thought to be a danger to motorists, consisting of only two undivided lanes, which during the summer months, the eastbound lane was usually at a standstill due to vacationers traveling to Newport via the main route from the mainland. Its steep climb proved challenging for some vehicles and with no passing lanes or shoulders, hazardous conditions resulted when stalled vehicles were on the bridge.
The roadway deck through the cantilevered span was an open steel-grid deck, similar to that of the Castleton Bridge just south of Albany, NY or the now demolished Sikorsky Bridge on the Merritt Parkway in Connecticut.
On the main span looking down through the grates, you were able to see Narragansett Bay.
