Video of a staircase most people use to get to and from Rio's famed Maracana stadium shows the structure built atop scaffolding wobbling under the weight of fans who attended the World Cup game between Argentina and Bosnia over the weekend.
Fans of various nationalities said Tuesday that they were scared it might come crashing down.
The footage shot by a Brazilian photographer showed people packed on the staircase of wooden steps as it swayed, grabbing hand rails to support themselves as they headed via their only exit to a concrete ramp leading to a subway station after the game.
"When people walk on it the wood moves, so with thousands of people walking up there, there could be an accident," said Jorge Martinez, a Mexican systems engineer who used the stairs to leave Sunday night's game.
The Rio de Janeiro state government issued a statement saying the staircase was inspected following complaints, reinforced and then re-inspected again Tuesday to ensure fan safety.
But fans who used it when it wobbled questioned why a more permanent staircase wasn't constructed out of concrete to ensure their safety.
On the other side of Maracana, a separate entrance for VIPs is all concrete, Juan Miranda of Chile said as he sat on the wooden staircase trying to buy tickets for Wednesday's game between Chile and Spain.
He said he saw construction workers soldering the scaffolding holding up the wooden staircase Tuesday morning.
