Editing Interstate 820 (section)

==History==
The highway was first conceived in 1949 as a [[beltway]] around [[Fort Worth, Texas|Fort Worth]]. It was originally designated from I-20 (now I-30) southeast, east, north, and west to I-35W. On April 18, 1963, I-820 was designated to use existing [[Texas State Highway Loop 217|Loop&nbsp;217]] from SH&nbsp;121 and SH&nbsp;183 to Hulen Street while the section of Loop&nbsp;217 from Hulen Street to [[U.S. Route 377 in Texas|US&nbsp;377]] was designated as [[Texas State Highway Loop 820|Loop&nbsp;820]].<ref name="SL 820">{{TxDOT|SL|820|link=no|access-date=December 22, 2022}}</ref> On September 1, 1965, another section of Loop&nbsp;820 from I-20 north and east to I-35W was designated. This section of Loop&nbsp;820 from I-20 north and east to I-35W became part of I-820 on January 21, 1969, making I-820 a full loop. The first section to open ran from McCart Avenue to US&nbsp;377 at a cost of $11&nbsp;million (equivalent to ${{Formatprice|{{Inflation|US-GDP|11000000|1963}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}). On May 13, 1977, the remainder of Loop&nbsp;820 became part of an extension of SH&nbsp;183. The southern leg of the loop was redesignated as [[Interstate 20 in Texas|I-20]] on December 2, 1971, and finished construction in 1982, completing a continuous loop around Fort Worth.<ref name="timeline">{{cite web |author= Staff |publisher= Texas Department of Transportation |url= https://www.txdot.gov/inside-txdot/projects/studies/fort-worth/interstate-820/timeline.html |title= I-820 Timeline |access-date= April 25, 2014 |archive-date= April 26, 2014 |archive-url= https://web.archive.org/web/20140426201131/https://www.txdot.gov/inside-txdot/projects/studies/fort-worth/interstate-820/timeline.html |url-status= dead }}</ref> Despite no longer being officially designated as I-820 on the southern arc (which is officially part of I-20), it is still unofficially referred to as Loop&nbsp;820 for business purposes, and the frontage roads and business addresses along the southern arc still bear the names "SW Loop&nbsp;820" and "SE Loop&nbsp;820".

The loop is often considered the most congested road in [[North Texas]], with the interchanges at Rufe Snow Drive, Holiday Lane, and Denton Highway (US&nbsp;377) being named the first, second, and third worst, respectively, in 2010.<ref>{{Cite news |last=Tomaso |first=Bruce |date=February 24, 2010 |title=Fort Worth's Loop 820 tops list of region's worst |url=https://www.dallasnews.com/news/transportation/2010/02/24/fort-worth-s-loop-820-tops-list-of-region-s-worst/ |access-date=April 25, 2014 |work=[[The Dallas Morning News]] |archive-date=April 21, 2022 |archive-url=https://web.archive.org/web/20220421223814/https://www.dallasnews.com/news/transportation/2010/02/24/fort-worth-s-loop-820-tops-list-of-region-s-worst/ |url-status=live }}</ref>

===North Tarrant Express===
{{Main|North Tarrant Express}}
The North Tarrant Express (NTE) was a construction project that was supposed to add additional lanes, [[high-occupancy toll lane]]s, and continuous frontage roads and reconstruct the interchange with I-35W and various other interchanges between I-35W and SH&nbsp;121/SH&nbsp;183. This plan, however, was modified, with the additional mainlanes not being built, though the [[Texas Department of Transportation]] (TxDOT) plans to widen the freeway by no later than 2030.<ref name=NTE/> The NTE began construction in October 2010 and was completed in June 2015.<ref name=NTE>{{cite web|author=Staff|publisher=Texas Department of Transportation|url=https://www.txdot.gov/business/partnerships/current-cda/north-tarrant-express.html|title=North Tarrant Express|access-date=April 25, 2014|archive-date=April 26, 2014|archive-url=https://web.archive.org/web/20140426201400/http://www.txdot.gov/business/partnerships/current-cda/north-tarrant-express.html|url-status=dead}}</ref><ref>{{cite web|author=Staff|publisher=North Tarrant Express|url=http://www.northtarrantexpress.com/ProjectTimeline.asp|title=Project Timeline for the North Tarrant Express (NTE) Project|access-date=April 25, 2014|archive-date=April 17, 2014|archive-url=https://web.archive.org/web/20140417030637/http://www.northtarrantexpress.com/ProjectTimeline.asp|url-status=dead}}</ref>
