Is It a Wonder of the World?

Two different lists
The confusion comes from two lists with similar names. The American Society of Civil Engineers picked a set of Wonders of the Modern World, engineering projects of the twentieth century, and the bridge is on it. The New7Wonders list came from a public vote and is made up of ancient and historic monuments; no bridge made it. When a search asks “is the Golden Gate Bridge one of the seven wonders,” the honest answer is yes on the engineers’ list and no on the voted one.
Why the engineers picked it
A 4,200-foot main span, towers 746 feet above the water, two cables holding 80,000 miles of wire, built in four years across a strait with strong tides and constant wind. The facts page lists the numbers and the history page tells how it was done. Whether that makes it a wonder is your call; the walk across is free, so you can decide from the deck. The walking page has the hours.
The view that usually settles the argument is from underneath, on the bay cruise, when the deck passes overhead at 220 feet.
Frequently asked questions
Which list is the Golden Gate Bridge on?
The American Society of Civil Engineers’ Wonders of the Modern World. Not New7Wonders. The facts page explains what earned it the place.
Is it the longest suspension bridge?
This site makes no claim about its rank. The main span is 4,200 feet between the towers. See the history page for the 1937 context.
What is the best way to see it?
Walk it, then see the underside from a boat. The cruise vs bike page compares the paid options.
