Controlled blasting at Roma Street

As part of the excavation of the underground station cavern and adits, the Cross River Rail Tunnel & Stations contractor will soon commence controlled blasting at the Roma Street site.

The Roma Street site contains areas of very hard rock. To break through this rock, controlled underground blasting will be undertaken in conjunction with other excavation methods.

The project team is planning to conduct small trial blast(s) within the underground cavern from mid- November 2020, site conditions permitting.


Following successful trial blasts, the project team will move to production blasting.

Controlled blasting will be carried intermittently at the Roma Street site from late 2020 until late 2021.

Blasting will be carried out between 7:30am and 4:30pm, Monday to Saturday. Blasts will not take place on Sundays or public holidays.

Nearby residents and businesses will be notified at least 48 hours’ ahead of controlled blasting.

An SMS alert will be issued 4 hours prior to controlled blasting.
