On Wednesday, $19$ July $2023,$ an explosion occurred in

the Johannesburg Central Business District $($CBD$),$

creating a tunnel. The official investigation revealed that

methane gas was the cause of the Lillian Ngoyi Street

$($formerly known as Bree Street$)$ blast. Floyd Brink, the

City of Johannesburg City Manager, revealed during a

media briefing that the explosion killed one person,

injured several others, caused infrastructure damage and

disrupted services in the area. Brink added that the

investigation ruled out several other suspected causes $-$

including that a gas leakage, illegal mining underground

or negligence caused the explosion.

Following the explosion, the City of Johannesburg spent

close to R$4$ million on "professional experts, services, the

cordoning off of the site, technology that was used and

the provision of temporary relief". The city manager said

repair work to rehabilitate and reconstruct the area is

currently estimated to stand at around R$178$ million and

that is based on preliminary work and designs. That

amount may increase based on the designs that they will

have and as they are moving closer with detailed designs.

Brink further said the City has learnt several lessons

following the explosion with plans coming to avoid future

reoccurrence.
