In both kilometers and miles, what is the world's longest jetty or pier?

The town of Progreso, Mexico, sits on a limestone shelf that falls away extremely gradually as it gets further out to sea. As a result, when they built a pier to allow cruise ships to dock here . Measuring a phenomenal 6.5 kilometers (4 miles), this is the world’s longest pier. http://googlesightseeing.com/2008/05/20/the-worlds-longest-pier/ May 06 09, 11:05 PM

According to this photo, the jetty at Lucinda, Queensland (Australia) is 7.5 km long. That would be about 4.7 miles. http://www.bugbitten.com/photos/Australia/Oceania/bradandwendy/Day_43_Leaving_Cairns/113561-17421-3948066.html May 07 09, 12:51 AM

The world's longest jetty is in Galveston, Texas. 6.74 miles, or 10.84 Kilometers long. http://www.swg.usace.army.mil/items/whatwedo/10.asp The longest pier in the world is the Progreso Pier in Progreso Mexico, which is 4 miles, or 6.5 Kilometers long, and was built to allow cruise ship traffic in the Gulf of Mexico to call at the colonial town of Merida. http://googlesightseeing.com/2008/05/20/the-worlds-longest-pier/ Side view: http://www.panoramio.com/photo/1904451 The longest pier/jetty in the Southern Hemisphere is in Lucinda, Queensland, Australia. It is 3.57 miles, or 5.76 kilometers long. The Lucinda Jetty is technically a pier, as it is structure suspended above sea level, but unlike many piers it runs diagonally from the shore, so that its pilings do indeed provide a bit of a breakwater to the shoreline. It's a cross between a jetty and a pier. One could call it a "petty" if one was not afraid of being jeered, or a 'jier' if one were not afraid of petty remarks. It is used strictly to offload bulk sugar to waiting ships. http://www.trekearth.com/gallery/Oceania/Australia/photo400565.htm Pier vs. Jetty: http://en.wikipedia.org/wiki/Pier http://en.wikipedia.org/wiki/Jetty http://en.wikipedia.org/wiki/Jetty http://en.wikipedia.org/wiki/Pier May 07 09, 7:26 PM
