Johannesburg CBD experienced an underground explosion on July 19 at Bree Street. It has been suspected to have been caused by the underground gas pipelines in the area. Motorists and pedestrians are urged by the Johannesburg Road Agency to avoid the areas to allow emergency and other critical services. Rosebank Killarney Gazette went to the street and asked residents what they think of the explosion, what they would do if they were there at that time and if they think the city responded well.
