EVERGREEN POINT FLOATING BRIDGE

The Evergreen Point Floating Bridge, also known as the 520 Bridge and officially the Governor Albert D. Rosellini Bridge carries Washington State Route 520 across Lake Washington from Seattle to its eastern suburbs. The 7,710-foot-long floating span is the longest floating bridge in the world, as well as the world’s widest measuring 116 feet at its midpoint.

PORTAGE LAKE LIFT BRIDGE

The Portage Lake Lift Bridge (officially the Houghton-Hancock Bridge), connects the cities of Hancock and Houghton, Michigan. It crosses Portage Lake, a portion of the waterway which cuts across the Keweenaw Peninsula with a canal linking the final several miles to Lake Superior to the northwest. The moveable bridge is a lift bridge with the middle section capable of being lifted from its low point of four feet clearance over the water to a clearance of 100 feet to allow boats to pass underneath. The bridge is the world’s heaviest and widest double-decked vertical lift bridge. More than 35,000 tons of concrete and 7,000 tons of steel went into the bridge which replaced a narrow 54-year old swing bridge.

WIDEST STREET IN THE WORLD

9 de Julio Avenue in Buenos Aires, Argentina is the widest street in the world. Its name honors Argentina’s Independence Day, July 9, 1816. The avenue runs roughly 0.62 miles from the Retiro district in the north to Constituciónn station in the south. The avenue has up to seven lanes in each direction and is flanked on either side by parallel streets of two lanes each. Through the center of the avenue runs one of the city’s Metrobus rapid transit corridors. There are two wide medians between the side streets and the main road. The avenue was first planned in 1888, but work did not start until 1935. The initial phase was inaugurated on October 12, 1937 and the main stretch of the avenue was completed in the 1960s. The southern sections were completed after 1980, when the downtown portion of the tollway system was completed.
