F&F TOWER – PANAMA CITY, PANAMA


The F&F Tower (previously known as the Revolution Tower) is an office tower in Panama City, Panama.

F&F Tower is a twisted building. A twisted is one that progressively rotates its floor plates or its façade as it gains height. There are 15 spiraled skyscrapers and 13 more are under construction.

F&F Tower holds the record for the tightest twist, that is, the highest average rotation per floor, at 5.943 degrees across each of its 53 floors, and is the completed building with highest total rotation, with 315 degrees.

F&F Tower has a total height of 796 feet. It is the 9th tallest skyscraper in Panama and the 14th tallest in Latin America.

INTERSTATE 70 (I-70) IN UTAH

 

Interstate 70 (I-70) is a mainline route of the Interstate highway System connecting Utah and Maryland. The Utah section runs east-west for approximately 232 miles across the central part of the state. 

Unlike most Interstate Highways, much of 1-70 in Utah was not constructed parallel to or on top of an existing U.S. Highway. Portions of 1-70 were constructed areas where previously there were no paved roads. Because it was built over an entirely new route, I-70 has many features that are unique in the Interstate Highway System. For example, the 110 miles between Green River and Salina makes up the longest distance anywhere in the Interstate Highway System with no motorist services. This same piece is noted as the longest highway in the United States built over a completely new route since the Alaska Highway, and the longest piece of Interstate Highway to open at a given time.

ASTORIA-MEGLER BRIDGE

The Astoria-Megler Bridge is a steel cantilever through truss bridge that spans the lower Columbia River, Between Astoria, Oregon, and Point Ellice near Megler, Washington. It opened in 1966 and is the longest continuous truss bridge in North America. 

The bridge is 21,474 feet in length and carries one lane of traffic in each direction. The cantilever-span section, which is closest to the Oregon side, is2,468 feet long and its main (central) span measures 1,233 feet. It was built to withstand 150 mph wind gusts and river water speeds of 9 mph.
