The venue has also hosted numerous concerts; on June 17, 2023, Taylor Swift's The Eras Tour performance was attended by 73,117 people, the highest-ticketed event in Pittsburgh history.

[16] Originally, a sales tax increase was proposed to fund three projects: Heinz Field, PNC Park, and an expansion of the David L. Lawrence Convention Center.

"[25] The Steelers and Panthers have their own locker rooms, which differ in size based on the number of players each team is permitted to dress for each game.

[27] A bronze statue of Steelers founder Art Rooney, similar to those located outside PNC Park, was moved 100 feet (30 m) from its previous position outside Three Rivers Stadium.

[29] In 2007, ESPN named the "tipping" of the oversized Heinz ketchup bottles atop the scoreboard one of the top ten touchdown celebrations in the NFL.

[39] Prior to the game, a speech from US President George W. Bush, ordering attacks on Taliban-controlled Afghanistan, was shown live on the stadium's JumboTron.

[45] While there has been talk of extending the Pittsburgh Light Rail to Oakland, significant costs were cited during construction of the North Shore Connector, which terminates at Acrisure Stadium.

[46] While the possibility of moving games back on campus with a purpose-built stadium has not been entirely dismissed by the university administration, it has also not been endorsed or featured in any strategic planning.

[52] After unsuccessfully trying to find another local company to purchase the naming rights,[53] the naming rights were bought by Michigan-based insurance company Acrisure in a deal initially reported on July 11, 2022; Steelers minority owner Thomas Tull also has an ownership stake in Acrisure.

Speculation and analysis mostly concluded that that attendance was primarily impacted by the success of the team and times that the games are played, not the location of the stadium.

[63] Since it opened in 2001, bands and artists including NSYNC, Beyoncé, Taylor Swift, Kenny Chesney, and LeAnn Rimes have performed at the stadium.

[69] Heinz Field hosted a women's international exhibition match between the United States and Costa Rica on August 16, 2015.

[70] On May 28, 2010, National Hockey League commissioner Gary Bettman announced that Heinz Field would be the host of the 2011 NHL Winter Classic.

Pittsburgh native Jackie Evancho sang the Star Spangled Banner before local sports legends Franco Harris, Jerome Bettis, and Mario Lemieux dropped the ceremonial puck.

In addition, they met with football players from the Steelers including Ben Roethlisberger, Hines Ward, and Brett Keisel.

After discussion with the NFL,[83] the Steelers owners decided to re-surface the field for their nationally televised game against the Miami Dolphins.

[84] After the new sod was laid, 1½ inches of rain fell[85] which did not allow the tarp to be removed from the field until 70 minutes before the game began.

[6] When the outdoor sports venue opened in 2001, both end zones were painted athletic gold during Steelers home games (this also happened for the final five seasons at Three Rivers Stadium), with "PITTSBURGH" on the north side and "Steelers" on the south side; both words were painted black with white outlines.

The design for the 2002 Wild Card matchup replaced the white letter outlines with athletic gold paint and removed it everywhere else.

Although the Steelers lost the game 21–16, team president Dan Rooney liked the look of the South end zone being "plain", and decided to bring it back the next year.

The 2003 season was the last year to date which contained "PITTSBURGH" and "Steelers" in black words with athletic gold outlines in both end zones.

In the aforementioned Dolphins-Steelers Monday Night Football match of 2007, the surface conditions had become so deteriorated from the rain and gameplay itself that the field grid of hash marks, yard lines, mid-field logo, and wordmarks in both end zones were barely visible throughout the game.

As of the 2011 season, Pitt and the Steelers in cooperation have their respective logos at midfield for their own homes games, being interchanged frequently.

[100] The Great Hall spans approximately 40,000 square feet (3,700 m2) on the east side of the stadium and houses a collection of Steelers and Pittsburgh Panthers memorabilia.

[101] Six large Super Bowl trophies-shaped display columns were erected and contain artifacts from each championship the Steelers have won including replica trophies.

Eight additional tile murals created by local high schools represent western Pennsylvania football history.

The temporary seating was left in place for the 2010–11 NFL playoffs, with the AFC Championship game on January 23 having a record attendance of 66,662.

[106] After contractors surveyed the complex the final number of 2,390 added seats with five additional suites including more parking, restrooms and concessions was determined in December 2014 to increase capacity to a total of 68,400.

[107] On September 10, 2016, the then largest crowd of 69,983 to ever see a sporting event in Pittsburgh watched the Pitt Panthers defeat the Penn State Nittany Lions, 42–39 as they renewed their rivalry in football.

On Steelers and Pittsburgh Panthers game days, access is also provided from Station Square parking facilities via the Gateway Clipper Fleet.
