Authorities on Tuesday announced that the Kai Tak Sports Park's main stadium will officially open on March 1.

The Culture, Sports and Tourism Bureau made the announcement on social media, where it said the 50,000-seat facility will be a “top choice venue” for international sports tournaments and large-scale entertainment events.

British band Coldplay will perform there on April 9, 11, and 12.

Separately, about 50,000 people participated in a drill at the sports park on Tuesday night, when the main stadium's retractable roof opened for the first time.

They watched a Hong Kong Premier League U22 match between Kitchee and North District.

With the roof open, the Environmental Protection Department also monitored audio levels to see if the noise generated at the venue could affect nearby residents.
