Editing Single-point urban interchange (section)

==History==
The first SPUI opened on February 25, 1974,{{Cn|date=January 2024}} along [[U.S. Route 19 in Florida|U.S. Route&nbsp;19]] ([[Florida State Road 55|State Road&nbsp;55]]), which goes over [[Florida State Road 60|State Road&nbsp;60]] east of [[Clearwater, Florida]]. It was designed by Wallace Hawkes, Director of Transportation Engineering at [[J. E. Greiner Company]] (later [[URS Corporation]])<!-- URS eventually acquired by AECOM, but Hawkes never worked at AECOM. -->, who has been called the "granddaddy of the urban interchange".{{Cn|date=October 2022}} This design has since been altered to include [[frontage road]]s in each direction.<ref>{{Cite web |title=Google Maps |url=https://www.google.com/maps/@27.9601938,-82.7302225,18.21z |access-date=2022-02-27 |website=Google Maps |language=en}}</ref>

Several SPUIs, built in the 1970s and later, are located on German autobahns, like the [[Bundesautobahn 40|A40]], [[Bundesautobahn 42|A42]], [[Bundesautobahn 44|A44]], [[Bundesautobahn 46|A46]], [[Bundesautobahn 57|A57]], [[Bundesautobahn 59|A59]], and [[Bundesautobahn 113|A113]] in [[Berlin]]. There is also a SPUI on the ''Frankenschnellweg'', the urban part of the [[Bundesautobahn 73|A73]], and Maximilianstraße, in [[Nuremberg]] (at {{coord|49.451708|n|11.038102|e|}}). Smaller versions of the SPUI can also be found on non-autobahn roads in German cities, with right-turning traffic under signal control, located in [[Heilbronn]], [[Karlsruhe]], [[Sindelfingen]], [[Stuttgart]], and [[Wiesbaden]].{{citation needed|date=January 2015}}

SPUIs are also found in Australia, Canada, Hong Kong, Indonesia, and Singapore.{{citation needed|date=September 2017}}
