The main span of this 11,248' (3428.4m, 2.1 miles) bridge is 1,600' (488m). [HistoricBridges]
The average daily usage in 2015 was 20,010 with 2% trucks. The navigation vertical clerance is 30.4m (100.1'). [NationalBridgeInventory]
The Mount Hope Bridge is another suspension bridge that helps connect Newport with the mainland.
The suspension span is on the west side of the bridge.

This bridge is like the Mackinac Bridge in that the suspended part is just a fraction of the total length. I could not find a length for the side suspended spans, but they look about half the distance of the main span. So the suspended part of the bridge is about 976m or 976/3428.4 = 0.28 of the total length.

"The bridge features an extremely long approach system of deck truss spans, deck plate girder spans, and concrete beam spans." [HistoricBridges]
The above street view shows some of the concrete beam spans and this photo shows some of the deck truss spans. The photo also provides a closeup of one of the cable anchors.

This bridge replaced a ferry service. The main span of this 2.1 mile bridge is 1,601' (288m). The towers are 400' (122m) high and provide a clearance of 215' (77m). "It remains the longest suspension bridge in New England." It carries 27,000 vehicles a day. Claiborne Pell was a senator. "An image of the bridge appears on the back side of the Rhode Island version of the U.S. quarter." [ritba]

With the Vertex of the Hexagon at the top and bottom. This allows a more rounded cable after compacting. Designed by Parsons, Brinckerhoff, Quade & Douglas.

This is an example of a tower design that looks simple, but strong.

This is one of several construction photos that are available on the BridgeHunter page. It is the second bridge I have seen where the tower is built with a derrick on a temporary tower on what I presume is a barge. I have not yet figured out how they "grow" the height of the temporary tower.

I found a higher resolution copy of the photo with the tower derrick.

You can also see workers tying rebar for the deck and in the foreground, the rebar for the barrier is in place. (Notice here the electrical conduits already inside the barrier bars.) |
