Constructed in the early 1960s, the Gateway Arch rises as a shimmering beacon across the St. Louis skyline as part of the Jefferson National Expansion Memorial.
Concocted by Finnish-American architect Eero Saarinen and structural engineer Hannskarl Bandel in 1947, the tallest habitable structure in Missouri was built as a monument to the westward expansion of the United States and has become a figure of sentimental value with both domestic and international visitors.
Now, the CityArchRiver 2015 Foundation and the National Park Service have organised The City + The Arch + The River 2010 International Design Competition to invigorate the park and areas surrounding the Gateway Arch, including the Missouri and Illinois banks of the Mississippi River.
Five shortlisted finalists are currently displaying their work in the Arch Lobby, open free of charge to the public until 24th September.
On 26th August, each team will present their concept to the competition jury in the Tucker Theater at the Arch, from 8am-6pm, with the announcement of the winner scheduled for 24th September.
The chosen project is slated for completion on 28th October 2015 in order to coincide with the 50th anniversary of the completion of the Arch... summaries of the concept designs can be viewed here .
