The Al Wahda Arches (also called 5/6 Arch, Qatar Arch, Gateway Arch) is a monumental pair of 20° inclined steel arches, spanning the "5/6 interchange" of the Lusail expressway, Qatar which connects West Bay with Lusail City. It is the tallest monument in the country and has received a 2020 International Design Award[1] and 2018 ENR Global Best Project award.[5] Intended to be viewed while in motion as an "immersive public artwork", the arches are connected to each other by a cable net – a reference to Qatar's pearl diving heritage.[1] The structure itself consists of 54 large steel pieces, weighing over 9,000 tons, while the base of the arches are clad in Limra Limestone from Turkey.[2]
