End of an era – Margaret Street overpass to go this weekend

The city skyline is changing with the final piece of the Margaret Street overpass that once connected government offices in George Street to be removed this weekend as part of the Queen’s Wharf Brisbane demolition of non-heritage buildings.

The final 35 tonne concrete beams that have cast a shadow over Margaret Street for 30 years were demolished last weekend, leaving only the pedestrian footbridge for removal.

The work on the Margaret Street overpass is a milestone in the construction of Queen’s Wharf Brisbane, a project that will transform Brisbane’s CBD with more than 12 football fields of public space and create a new world-class entertainment precinct for locals and visitors.

Destination Brisbane Consortium Project Director Simon Crooks thanked the community for its support and patience during the demolition process.

“We realise that weekend road closures and night time works may be inconvenient and we appreciate the patience everyone has shown during the demolition process,” Mr Crooks said.

“This is the largest CBD redevelopment in Queensland’s history and we have been mindful to ensure that all members of the community are kept informed during the current work activities.”

Demolition of the overpass and the neighbouring 80A and 80B George Street buildings has taken place over seven weekends. This weekend is the last scheduled closure for Margaret Street as part of demolition activities.

“More than 2,750 tonnes of concrete made up of 1,640 tonnes of beams, 600 tonnes of topping slab, 320 tonnes of trusses and 160 tonnes of header beams and columns have been removed during the demolition of the Margaret Street overpass,” Mr Crooks said.

“Our contractor Probuild safely achieved this result above a live road and with more than 678,000 pedestrian movements beneath.

“We knew demolition of the overpass was going to require Margaret Street to be closed (from the Riverside Expressway to George Street) so that it could be done safely without risk to motorist or
pedestrians. To help offset the inconvenience we worked closely with government and transport authorities to schedule the work over weekends when CBD traffic is at its lowest with least impact to motorists.

“Safety of workers, commuters, pedestrians, motorists, cyclists, locals and visitors has been a high priority during the demolition stage and we will continue to make the project site a safe environment through all stages of development.

“The next major demolition milestone will be the leveling of 80A George Street and the Neville Bonner Building (down to William Street) expected in October, and by November, 80B George Street is also expected to be demolished.

“The Executive Building, which now sits at level 10 should be at ground level around the end of the year.”

Excavation on the site is expected to begin in 2018, subject to planning approvals, once demolition of the three non-heritage buildings within the Queen’s Wharf Brisbane site is complete.
