Where is the longest stone arch bridge in the world?

Bulkeley Bridge

The Bulkeley Bridge is one of the oldest bridges in use in the Interstate Highway System. It is also the longest stone arch bridge in the world. The Bulkeley Bridge is named for Connecticut governor and United States Senator, Morgan Bulkeley.

The Bulkeley Bridge (also known as Hartford Bridge, Bridge No. 980A) is a stone arch bridge composed of nine spans located in Hartford, Connecticut. The bridge carries Interstate 84, U.S. Route 6 and U.S. Route 44 across the Connecticut River, connecting Hartford to East Hartford. As of 2005 the bridge carried an average daily traffic of 142,500 cars.

Actually, its the Rockville Bridge just north of Harrisburg, Pennsylvania.

The Rockville Bridge, at the time of its completion in 1902, was, and still remains, the longest stone masonry arch railroad viaduct in the world.

From your link, you didn't specify that it was the longest stone masonry arch railroad viaduct in the world. Your question was the longest stone arch bridge in the world.

Quote: Okay all you Rockville Bridge fans. I was right (as far as I can tell). While the railroad bridge is impressive and far, far more attractive than the more utilitarian Bulkeley Bridge, it is merely longer, but not â€oelarger.â€?

The Bulkeley consumed â€oeover 100,000 cubic yardsâ€? of pink granite. The Rockville consumed â€oealmost 100,000 cubic yards of masonry.â€? also, the Bulkeley has larger arches, (90 feet vs. 70 feet) for what thatâ€s worth.

And while the difference between â€oelargestâ€? vs. â€oelongestâ€? is admittedly silly, it IS a difference worth noting and I am confident enough to stick with my designation.

The Bulkeley consumed "over 100,000 cubic yards" of pink granite. The Rockville consumed "almost 100,000 cubic yards of masonry." also, the Bulkeley has larger arches, (90 feet vs. 70 feet) for what that's worth.

And while the difference between "largest" vs. "longest" is admittedly silly, it IS a difference worth noting and I am confident enough to stick with my designation.
